MIDWEST STINSON REGIONAL FLY­ IN

Everything went so well last year that the hosts are going to do it again . The Second Annual Midwest Stinson Fly-In is set for September 12-14, 1986 at Jacksonville Airport, Jacksonville, Il­ linois. Events include a fly-out breakfast on Saturday morning with special con­ tests on the return flight, seminars, ban­ quet, brunch, flea market and lots of fly­ ing. A camping area and grills for cooking will be provided by airport manager, Sally Prewitt. For those who prefer motels, transportation is available be­ tween the airport and the Holiday Inn. For more information on this event, contact Loran F. Nordgren, P. O. Box 710, Frankfort, IL 60423, phone 815/ 469-9100.

SEARCH RENEWED FOR NUNGES­ SER & COLI

On May 8, 1927 (12 days before Lindbergh's trans-Atlantic flight) Charles Nungesser and Francois Coli departed Paris bound for New York where they hoped to land the following day. If successful the two Frenchmen would be the first to fly non-stop from Europe to North America. After take off they dropped their big biplane's landing gear and shortly thereafter were re­ ported over Ireland. They were never seen again. Their airplane was named l'Oiseau Blanc (White Bird) and was de­ signed to be landed on water after pos­ itioning the propeller horizontally. Several unconfirmed sightings of the plane were reported in Maine on May 9, but exhaustive searches on both land and water revealed nothing. However, reports by two witnesses, one of which came to light quite recently, indicate that the two Frenchmen may very well have flown the Atlantic and crashed in the Maine woods after running out of fuel and attempting to land on a lake. An organization known as the Inter­ national Group for Historical Aircraft Re­ covery (TIGHAR) will have completed a highly organized search of a specific area in Maine by the time you read this. We will keep you informed. 4 AUGUST 1986

EARLY AVIATON MAGAZINE

PILOT REPORTS

by Dennis Parks EAA Library/Archives Director "After running the motor a few min­ utes to heat it up, I released the wire that held the machine to the track, and the machine started forward into the wind ." - Orville Wright, Flying, De­ cember, 1913, p. 36. Though possibly not the first pilot re­ port in an aviation journal, it sure is the pilot report of the oldest aircraft. In the December 1985 issue of VIN­ TAGE I issued a call to locate the oldest flight test of an aircraft conducted and written by a staff member of an aviation journal. The goal was to locate the source of the now standard and popular pilot re­ ports in the general aviation magazines. It is known that after WW II these be­ came a regular feature of magazines such as Air Facts, Flying and Skyways. Upon examination I was able to deter­ mine that Air Facts had been doing this since a report on the Waco N in 1939. These tests reported by Leighton Col­ lins were excellent reports on the be­ havior, especially from a safety view­ point, of the subject aircraft. These re­ ports were later reprinted in two vol­ umes called the Air Facts Reader. The first volume covered 1939 to 1941 , the other 1942 to 1947. Most of the magazines before the war in reporting on new aircraft basically just reproduced the information provided by the manufacturers. Some exceptions were flight test reports by military pilots about military aircraft. I knew that Sportsman Pilot also re­ ported flight tests, but was not able to determine when they began such re­ ports as the library did not at that time have available any issues predating the library's issues of Air Facts. Thus I de­ cided to approach our readership. One of the first responses was by Terry Ladage of the Institute of Aviation , University of Illinois. Mr. Ladage pro­ vided a copy of the Orville Wright report on the 1903 Wright Flyer. Though it did not meet the criteria it is definitely an historic pilot report. Orville Wright reported that there were handling problems with the Flyer.

The problem was in pitch response which caused an "exceedingly erratic flight. " The second flight was much like the first but the third was steadier than the first till a "sudden gust from the right lifted the machine up twelve to fifteen feet and turned it up sidewise in an alarming manner." Orville warped the wings to recover and headed for the ground to land, but the lateral control was very strong. "The lateral control was more effective than I had imagined and before I reached the ground the right wing was lower than the left and struck first. " Wilbur, who flew the second flight, flew the machine for the fourth time that day. By the time he had covered 300 feet, ''the machine was under much bet­ ter control. The course for the next four or five hundred feet had but little undu­ lation." However, at about 800 feet dis­ tance , the Flyer began to pitch again and struck the ground at a distance of 852 feet. We have all read of the first flights of this aircraft but thanks to the reports of the pilots who flew it we are able to know what the machine was like to fly. The winning entry was submitted by Mr. Charles W. Harris of Tulsa, Ok­ lahoma who sent a copy of the "Sportsman Test Pilot" article from the July 15, 1936 Sportsman Pilot. This was a pilot report by Franklin T. Kurt on the Lambert Monocoupe. This report is an in-depth report spread over four pages. The report started with entering the aircraft and its general characteristics : "Getting in is not very difficult, though one is annoyed by the cabin full of con­ trols around his ankles .... With the exception of the controls we found the construction neat and simple .. . . The engine compartment is pretty short, so much so that the magneto points are reached through a door in the fire-wall ." The pilot on the appearance of the plane: "Whoever supervises the fabric and doping work at the Lambert Aircraft is a master craftsman ." Comparing it to other aircraft. "It sells for well under $4,000 yet provides performance not matched in several higher price brac­ kets."

Going aloft Mr. Kurt reported on its behavior: "Flying alone, the stability of the little ship is as near neutral as we have seen lately . .. It very nearly pOints where it is put, with only very slow return to level flight"; and found it very favorable : "We have flown very few planes where each control brought such quick and effort­ less, yet well damped, response"; "She went into an extremely prompt spin . We recovered in haste and found the con­ trols so effective and the recovery so quick that we went a little grey." The overall rating was very positive: "She takes two people further in less time and for less money than any known ship." The flight tests of Franklin T. Kurt and Leighton Collins (Air Facts, see De­ cember 1985, January 1986 VINTAGE) provide a great deal of insight to the behavior, construction and perfor­ mance of light aircraft. Recently I was fortunate to receive a letter from Mr. Collins in which he talks about Mr. Kurt. "Starting, as I recall in the late '20s, and certainly through the '30s, he wrote in almost every issue of The Sportsman Pilot magazine a flight test article. They were the best ever published in my opinion." He stated that Mr. Kurt was a Navy trained pilot and the first person to re­ ceive a degree from MIT in aeronautical engineering. Mr. Kurt spent most of his aviation career as an engineer and test pilot with Grumman at Bethpage, Long Island. "For his articles the aircraft manufac­ turers would bring their airplanes either to Grumman Field or else the nearby Aviation Country ClUb ." Special thanks to Mr. Collins for his insight into this matter. As it stands now we have to credit The Sportsman Pilot for conceiving of a series of regular pilot reports for its reader. I have recently received copies of flight tests from some 1934 issues of the magazine. These were of the Lambert Monocoupe (September, 1934) and the Taylor E-2 Cub (December 1934). These tests were done by Lewin B. Barringer. I'm sure this is not the end of the story. Let's hear from those of you who can shed additional light on this matter .• VINTAGE AIRPLANE 5


5500 MILE FLIGHT ON LESS THAN 40 HP

Author Robert A. "Bob" Geier be­ came a C.A.A. Aeronautical Inspec­ tor about a year and half after this flight. He served in that capacity until after World War /I when he left the C.A.A. to run a flying school in Santa Ana, California. Just .before his stint with the C.A.A., Bob taught his brother, Ber­ nie Geier, to fly. When Bernie re­ turned from the service he got his flight instructor's rating and taught in Bob's school for a number of years prior to going to work for the FAA. Bernie Geier is well known to EAAers as he worked closely with EAA for many years when he was with Flight Standards in FAA's Washington headquarters. Geier and Sammy Galloway pose with their Taylorcraft at the Butler Pennsylvania Airport. This photo, taken by Bob's parents, is the only one taken during their long trip. The boys could not afford the extra weight of a camera on board.

by Bob Geier 2727 De Anza Road, #1-17 San Diego, CA 92109 With a Continental A-40 engine de­ veloping somewhat less than its "when new" 40 hp, in a 1930s Taylorcraft Model A not equipped with brakes, lights, radio or instruments other than airspeed, altimeter and compass, two men made a 5500 mile round trip flight from Santa Ana, California to Pittsburgh, Pennsylvania in May, 1940. Enroute in NC18320, SIN 53, they ex­ perienced four emergency landings (two were "dead stick"), a very near­ miss mid-air collision, a forced power dive to prevent being sucked up into a thunderhead, in-flight "re-fueling" and extended wide open throttle settings to barely clear mountain passes. In 1940, the "standard" power plant of the average personal light plane was either the Continental, the Lycoming or the Franklin 65 hp horizontally opposed, 4-cylinder air-cooled engine. But even the 65 hp engines provided considerably more cross-country capa­ bility than the single-ignition 40 hp power plant used by these men in their long essentially coast to coast round trip flight in 1940. A study of the air charts revealed a number of segments in which airports with available fuel supplies were farther apart than the approximate 225 mile maximum cruising range of the aircraft's ten gallon fuel tank. This range was ex­ pected to be shortened by the need for 6 AUGUST 1986

full throttle operation at slower climbing speeds to clear high elevations enroute. A ten gallon fuel tank was situated in front of the instrument panel, with the gas filler cap immediately in front of the windshield. There was a wire rod through the cap with a piece of cork on the bottom floating on the fuel. The height of the rod above the cap indi­ cated the volume of fuel remaining. When its bent end rested on the cap, there was approximately 20 minutes of fuel remaining. The baggage compartment was a canvas sling behind the seat about a foot deep. This was just about right to hold three two-gallon round gasoline cans, which gave a total 16 gallon ca­ pacity to the aircraft. The men took a spare gas can cap and soldered a bicy­ cle tire valve in one side and a length of tubing in the other. The tubing ex­ tended from the bottom of a gas can through the cap and about two inches above the top of the can. They also sol­ dered a piece of tubing bent at a 90 degree angle into the aircraft filler cap, so that when the cap was in place, the tubing pOinted directly toward the windshield. A small hole in the windshield b~hind the end of the bent tube allowed a piece of neoprene hose to be pushed through from the inside of the cabin on to the tube, while the other end of the hose attached to the gas can tubing. A bicy­ cle tire pump completed the refueling system. As pressure was pumped into

the can, the gas flowed into the main aircraft fuel tank, and voila, there was "in-flight refueling." This gave a maximum possible range of 360 miles at cruising throttle, and somewhat less at full throttle. The two men, Sammy Galloway, owner of the plane who got his Private Pilot license the day before departure, and Bob Geier, who held a Commercial Pilot certificate, hoped to visit their rela­ tives in Aledo, Illinois and Pittsburgh, Pennsylvania respectively. Other than extremely rough air near Palm Springs, California, the trip was uneventful until after leaving Tucson, Arizona. In greater than 100 degree heat, the plane refused to climb over 3000' while needing 4000' to get past Wilcox, Arizona. Mountains a few miles to the North were downwind, and flying to them, the men flew parallel to their face, keeping the wing tip as close to the mountain side as possible, and found the updraft strong enough to lift them to 5500', enough to get to Lordsburg, New Mexico. But the relief was short lived. The en­ gine began to miss-fire. While trying to decide what to do, the engine started running properly again and continued so for a little while until they hit some rough air, when the miss-firing re­ sumed. But the periods of proper run­ ning were long enough, and the periods of miss-firing short enough that they were still able to maintain the altitude they had reached, so they decided to


take a chance and head for Lordsburg. After landing they determined the problem to be a loose carburetor. After tightening same and making a take off, they found the plane would not climb. Fifteen foot wires had to be cleared, so, just before reaching them, they pulled the plane up, having just enough ex­ cess speed to climb over them, but they had to dive back down to keep from stal­ ling. Leveling out a few feet above the ground, they found that the cushion of somewhat compressed air close to the ground, formed by the moving aircraft wing, continued to sustain the plane, but an attempt to climb simply lost airspeed of which there was little to spare. By the time they had flown some fifty miles of such hedgehopping, even­ ing cooling permitted some climb ability. They made EI Paso, Texas and an early start the next day permitted them to barely clear the Guadelupe Pass and get to Big Spring, Texas. The enjoyable relaxation after the arduous periods of flight in reaching Big Spring was most welcome. But their relaxation was not to last. After leaving Duncan, Oklahoma and nearing Oklahoma City, the engine again began to miss-fire. They were near the small town of Lindsay, and a long narrow farm field showed up. A circling of it showed a farm house on one long side near the middle, and a fairly high power line along the other long side. There was a ditch at the far end of the field . An emergency landing was made on it. After checking the engine over and making some minor adjustments, they took off. The engine performed beauti­ fully for the take off and climb to about fifty feet when it stopped completely. They were too high and too far down the field to land within it. Turning upwind would have taken them into the power lines. Immediately to the left and down­ wind was a plowed field which would surely send the plane over on its back. Beyond the plowed field was grain field and they figured the tail wind would given them just enough help to make it, and it did. Removing the magneto, they had it worked over by a mechanic. A short test hop indicated no further trouble, so they decided to resume their trip. A little head wind permitted a fairly short take off and they made a low circle of the farmhouse , wagging the wings in farewell to the farmers when the engine suddenly stopped. Now they were too low and had no tail wind to get across the plowed field, which was worse for landing than before because it had been soaked by rain . The only possibil­ ity was the remaining short length of the field from which they had taken off and they quickly put the plane into a steep side slip reaching the ground for a land­ ing less than 100 feet from the ditch.

Without brakes there was nothing to do but ground loop at the last moment. The plane stayed on its wheels and fortu­ nately there was no damage. This time a new coil was put into the magneto and the trouble was over. Re­ suming their flight, they were approach­ ing Jefferson City, Missouri when they were startled as a plane coming from behind dove immediately in front of them , at a fairly high rate of speed and with what appeared to be less than 50 feet to spare. They never did determine whether it had been an accidental near­ miss, or an intentional scare stunt of a reckless, immature pilot. The first destination, Aledo, Illinois, Sammy's hometown, was reached on May 11 , after six days of traveling and 29 hours and 50 minutes of flying . A trip by auto would have been as quick, but it would not have been nearly as much fun - or as exciting and interesting. After a number of landings on a rough pasture in Aledo, giving rides to friends and relatives, the bungee cord on the tail wheel broke. They tied it together temporarily and flew on. But the troubles, in addition to the tail wheel , were not to be denied . With the flight to Pittsburgh about half com­ pleted, the wire "gas gauge" on the main tank slowly began to drop its rate of descent considerably faster than what would be normal fuel usage. They climbed to a higher altitude, while one of the gas cans was made ready to use. Connecting everything up they were ready to pump up pressure the second the engine sputtered, plan­ ning to put the plane into a dive to keep the propeller turning while they got gas into the tank. Now it was simply a matter of waiting. Fortunately, the trouble was only in the gas gauge and they made Pittsburgh, and later, Butler, Pennsylvania where they gave friends and relatives airplane rides. The last one to get a ride was Helen, and her's would be different from the others. The weather had been heav­ ily overcast all day, and flight was rather smooth with moderate winds. Ordinar­ ily, a flight in the slow climbing plane took all the way to the nearby town of Butler to gain a thousand feet. Shortly after take off, altitude was gained rapidly and over a thousand feet was reached within a short distance of the airport. Soon the plane was travel­ ing through wisps of clouds, and in spite of cutting back the power and nosing down, it still continued to rise. Bob had to apply power and dive steeply to pre­ vent being sucked into the thunderhead by the strong updraft. After a few days visit, they left the Pittsburgh area and headed back to Aledo. They were near the small town of Jackson Center, Ohio when the weather required them to find an emergency landing spot to sit out a

storm. They hoped it was just a squall which would pass over in a short time. They spotted an ideal wheat field with a large barn on the north side to serve as a windbreak. The landing was no problem. They stationed themselves under the wing panels where they would be protected from the rain and at the same time help to hold the plane steady. It was not long before the rain came and it was heavy. Had they been caught in it aloft, visibility would have been re­ duced to instrument conditions for which neither the pilots nor their plane was qualified. They weathered the storm and continued on their way. After another visit to Aledo, they con­ tinued southwestward to Big Spring. Then intending to stop at Wink, Texas for fuel they decided not to sacrifice the altitude they had then gained and con­ tinued toward the Guadalupe Pass. Ad­ ditional altitude became harder to get as they got nearer and nearer the pass and considerable doubt as to their abil­ ity to clear it arose. Their hearts were troubled and their prayers intensified as they found themselves within a few feet of the ground and near the ridge. There was a fairly narrow wash crossing the ridge which was some ten feet deep and they guided the plane through it to take advantage of that small additional clearance. They had been operating at full throt­ tle for some time and found that altitude maintenance required its continuance. With everything indicating fuel exhaus­ tion, they finally made EI Paso, and were able to taxi to the parking area and fuel pumps. They had been in the air three hours and fifty minutes since leaving Big Spring, almost all of which was at full throttle. The main 10 gallon tank took a little over 9-1 12 gallons to fill , and they put 6 gallons in the three auxiliary cans. They realized that had the airport been 15 miles farther they would have run out of gas before reach­ ing it. They had just made it. Leaving EI Paso early in the morning , they had little difficulty in clearing the Wilcox Pass for a landing at San Simon, Arizona, and rough air was the only dis­ comfort they experienced to the Ban­ ning, California pass, when again they had to use the mountain-induced up­ drafts to obtain sufficient altitude to cross it. After more than 86 hours of flying , 11 of it in local sightseeing flights, they re­ turned to Santa Ana. The little monop­ lane had gone through wind , storm, rain , forced landings, and near crashes without damage. Taking 75 hours to cover roughly 5500 miles, its ground speed had averaged very close to its cruising air speed at 70 mph, all on less than 40 hp without brakes, lights or radio, and with only a compass for navi­ gation .• VINTAGE AIRPLANE 7

Although it fea­ tures the design lines of a popular airplane of its day, the actual story of its origin is unique. The photo was submit­ ted by John Underwood of Glendale California. Answers will be published i~ the November, 1986 issue of THE VIN­ TAGE AIRPLANE. Deadline for that issue is September 10, 1986. The Mystery Plane in the May, 1986 issue of THE VINTAGE AIRPLANE is a Thunderbird W-14, first built in 1926 in Los Angeles, California. J. W. "Bill" Knepp of Bartonville, Illinois correctly identified the airplane and wrote : "The Thunderbird was, most cer­ tainly, one of those airplanes that de­ served more than it was given. A very advanced design that became the vic­ tim of management problems. In avia­ tion history there were a number of planes that can be placed in that cate­ gory." He also sent a copy of an article on the Thunderbird by Jim Dunavent which appeared in the August, 1964 issue of Model Airplane News. The Thunderbird was designed by Theodore Woolsey for the W-F-W Airplane Co. headed by Jack Frye and financed by Paul Whittier. Frye made the test flight of the first Thunderbird on July 11 , 1926. Production was started in early 1927. ATC approval was given under Memo 2-141 . Besides the OX-5 engine used in the first Thunderbird, the approval covered the 150 hp Hisso, the 120 hp Bailey C7R and the 140 hp Floco engines. Thunderbirds became well known for their speed and climbing ability. In 1927 one set a speed record for commercial planes of 100 hp attaining a speed of 114 mph in a race at the Santa Ana,

that year a stock model Thunderbird with a high compression OX-5 engine averaged 119.4 mph in four trials over a test course. A number of Thunder­ birds were purchased before production ceased in 1929. Additional references: Aviation, August 15, 1927; Aero Digest, October, 1927 and January, 1928.

Restoration Corner

Editor's Note: In this, the seventh instal­ lation of the "Restoration Corner", well­ known vintage aircraft restorer Stan Gomoll of Minneapolis, Minnesota dis­ cusses general techniques used in ren­ ovating tail groups and wings . .. G. R. C.

TAIL GROUP AND WINGS by Stan Gomoll (EAA 44419, AlC 369) Tail Group

The types of construction used in air­ craft tail groups falls into three general categories : steel tubing, aluminum and wood . Some of the aircraft utilizing wood construction in their tail groups are Mooneys, Culvers, Wacos and Fair­ childs, to name a few. Start by laying all the parts on the floor in plan form . Now is the time to check for pieces that are missing or may have been misplaced, such as trim actuator brackets, hinge pins, brace wires and attaching hardware. Make a list of missing parts along with a work­ sheet of the work to be accomplished ; then when you set the piece aside awaiting parts or material, you can pick up where you left off. Check for ADs or factory service bul­ letins which may apply to your aircraft. These could refer to such things as at­ tach points, hinge brackets, internal cor­ rosion or wood rot. Steel Tube Construction

Clean all the parts using soap and water, paint stripper or sandblasting. I do not choose to sandblast unless it is absolutely necessary as this process removes the natural protective coating on the metal. Wire brushing will clean the surface, but leaves rust in pitted areas and inside small radius corners. If you do choose to sandblast, care must be taken because it will reduce the thickness of the material and can distort light sheet metal parts. After cleaning and removing all the rust, punch test the tubing using a dull­ pointed punch and hammer. Also check for any cracks or distortion. A check for mis-alignment of hinges can be made by standing the part vertically and run­ ning a weighted string through the

10 AUGUST 1986

holes. When there are more than two hinge pOints on a surface, the alignment becomes more critical. Replace worn bushings by pulling them in. A simple puller can be made using a threaded bolt and socket or a piece of tubing with a large, heavy washer welded on one end . This works well on straight-type bushings or roller bearings. If the trim tab on the control surface is mounted with bolts or PK screws, it might be necessary to weld a reinforce­ ment in this area to prevent cracking of the thin trailing edge tubing . After each part is repaired and cleaned, give it a coat of primer. I like to use lacquer-resistant zinc chromate or a good epoxy primer. Adjustable trim tab actuators should be disassembled, cleaned and re-as­ sembled using a grease with a wide temperature range. Check cables for condition and proper clearance from structures. Make a drawing to be used in locating accurately the inspection plate holes after the new covering is in­ stalled. Check, and if necessary, replace the wiring for the navigation light. You might want to install extra wiring for the possi­ ble installation of a strobe light at a later date. After all the tail pieces are cleaned, repaired and primed, take the time to mount the complete assembly on the fuselage . It's much easier to take care of mounting problems now than after the pieces are covered . At this time do a complete rigging of all wires and/or struts for the tail group, including hook­ ing up any adjustable trim tabs . Check for adequate clearance between parts, taking into consideration the added thickness of one or more layers of fabric and/or tape. Also, it's easy to rig the proper travel of trim tabs and control surfaces at this time. Use the FAA or manufacturer's specifications to deter­ mine the proper degrees of travel. Aluminum Construction

Check for loose rivets, cracked or broken internal structure, improper re­ pairs, and corrosion inside and out. Check for mice or bird nests which hold moisture, causing corrosion . Check that all drain holes are open. If the surfaces are painted, you might want to strip the paint to check for hidden damage or re­ pairs. Some unscrupulous persons

have been known to cover such areas with bondo. Check to see that all repairs are co­ vered on Form 337s. It's not uncommon to find that the proper paper work has not been completed. Wood Construction

The small blade of a pocket knife is a good tool for checking the condition of wood structure. The point should penetrate very little into the wood. I suggest trying this on a piece of scrap wood to "get the feel." The blade will penetrate very easily into decayed wood. It's advisable to replace all hardware (bolts, nuts, washers, etc.) as cadmium plating wears off and moisture in the wood can result in rust on these areas, which in turn , causes the wood to decay with a major loss of strength. Even though the hardware may look good, it should be replaced. It has probably been installed a long time and with the long life of today's modern fabrics it will be a long time before the plane is re-covered again. Pay particular attention to the area around the attach points. All of the old paint should be removed down to bare wood so a good check can be made for cracks and dry rot. Check all glue jOints and gussets for strength and/or separa­ tion . The old casein glues deteriorate with age. Check FAA Manual Part 43 which de­ scribes repairs to wood and metal struc­ tures. The old standby is to finish the wood. with two coats of spar varnish , as this product has stood the test of time. To make an internal inspection of tail pieces covered with plywood and con­ taining no inspection openings, it may be necessary to cut holes - but first check with your AI or FAA inspector. There are a lot of qualified people to answer questions concerning your re­ storation project - all you have to do is ask. Available through EAA Head­ quarters the year around are many "how to" manuals. These are also avail­ able at the EAA Sales Building during each annual Convention at Oshkosh, as are many educational forums and work­ shops covering every aspect of aircraft construction and restoration . Another good source of information is local EAA and Antique/Classic chapter fly-ins and fly-ins sponsored by the various type clubs.


As mentioned in previous "Restora­ tion Corner" articles, there are com­ panies who sell reprints of aircraft and engine manuals. These companies ad­ vertise in Trade-A-Plane and several aviation magazines and are well worth knowing about. Wings To remove fabric covering, first re­ move the rib stitching by cutting the cords. If the fabric is secured by metal clips, these must be removed carefully to prevent damage to the metal ribs. Whether constructed of wood or metal, most wings are delicate structures and can be damaged easily. Either save the old fabric or make patterns from which the location of inspection holes and control cable openings can be deter­ mined when the surfaces are re-co­ vered. After the covering is removed an evaluation of the condition of the wing is next on the agenda. Continuing with your worksheet, make a list of the fol­ lowing items along with pertinent re­ marks: Leading Edge - note wrinkles, cracks, previous repairs, corrosion or plywood separation. Wings are fre­ quently stored with their leading edges down creating a natural trap inside the leading edge covering for moisture re­ sulting in corrosion and/or wood rot. Ribs - note previous and/or unre­ paired damage, wood rot, loose glue joints and gussets, damage to capstrips caused by wire or PK screws, ribs mis­ shapen because of over-taut fabric or bowed due to over-tightening of drag and anti-drag wires. Butt ribs - same as above. Ribs at aileron space - same as above plus distortion resulting in too lit­ tle or too much clearance from the aile­ ron. Spars - note condition of finish, any cracks or elongated holes causing loose bolts at metal fittings. Are the spars straight and in alignment when sighting down them length-wise? Are all the ribs the same height from top of spar? Were previous repairs made in accordance with Part 43 and properly noted on a Form 337? Trailing Edge - note condition. Is it straight and in alignment with aileron trailing edge? Aileron Hinge Brackets - check bearings and bushings for wear. Do bearings rotate freely? Check security of attachments - are they bent or cracked? Drag wires and compression mem­ bers - are the wires rusty, broken or loose? Do they have a heavy build-up

of paint applied by brush? If compres­ sion members are wood, have they shrunk causing ribs to bow? Navigation and landing lights ­ check mounting brackets for cracks and security, unnecessary screw holes in the wood , nut plates or tinnerman nuts missing or worn out, and condition of wiring. If the landing light is retractable, does it operate properly? Ailerons - check general condition of structure. Depending on construction materials, is there rust, corrosion, wood rot, loose rivets or glue joints? Are hinge attach points secure? Is the trailing edge straight and aligned with wing trailing edge? Check leading edge for cracks and/or wrinkles - these are usu­ ally visible even through the finish paint. Some ailerons are counterbalanced with lead weights in either the leading edge or mounted on external arms. Check these for a good, solid attach­ ment. A decision must be made at this point whether to completely disassemble the wing panels or to restore portions of them . If you decide to totally restore the wings, be sure to do one panel at a time, leaving the other(s) assembled to guide you in re-assembly of the rebuilt unit. When possible, the route I like to take is to remove the leading edge covering, drag and anti-drag wires, and compres­ sion members, leaving the spars and ribs assembled. This procedure allows a good cleaning and checking of the structure. I then re-finish the wood with a minimum of two coats of spar varnish , and the metal parts with a good primer followed by a good covering with black enamel. Primer alone does not give long term protection. Reassemble the wing panel using all new hardware. Aluminum structures can experience electrolytic action between the aluminum and steel fittings (dissimilar metals) resulting in corrosion. The use of cadmium plated bolts will neutralize this action. An advantage in restoring a classic rather than an antique aircraft is that many new parts are available from sup­ ply houses. If this describes your pro­ ject, the next step is to sit down with catalogs from several supply houses and make a list of parts needing re­ placement and which are available. Get that order off right away as delivery may take some time. A good example of new replacement parts is a repair kit for the metal ribs and spars in Piper aircraft. In some cases, leading edges can be bought pre-formed or you can make them your­ self. When re-assembling a wing, to get the proper height and fit of the ribs on

the spar, make a pattern off the spar attach points and the top of the fuselage (high wing monoplanes or cabin bip­ lanes). Using a wing rib pattern sawed out of plywood, line up the leading and trailing edges of the ribs with nose ribs in place aligned with main ribs. The ai­ lerons should be in place to assure proper alignment and clearances. The trammeling process comes next. Don't be alarmed at the thought of doing this as it is simple if done according to the book. It's just a matter of tightening the drag and anti-drag wires in se­ quence, keeping each bay square and the spars straight. This must be done before the leading edge sheeting (if used) is installed. Wood leading edges are more dif­ ficult to repair or replace. The wood sheets have to be pre-bent over a form with a smaller radius than that of the rib curvature . Start by soaking the plywood in water overnight, then clamp it to the form with wide straps. Old seat belts work well for this. Do not try to fully bend the sheet at one time, but tighten the straps gradu­ ally. The use of an electric steam iron set on "full heat" and applied directly to the wood surface helps to bend the wood without cracking, thanks to steaming action. It's of utmost importance to trammel the wing before final installation of the leading edge sheeting. For holding the sheeting in place I made a set of clamps which work great for either wood or aluminum. I cut several pieces of 2 x 4 four inches longer than the height of the spar, then fastened one end of each strap (seat belt) to one end of each 2 x 4. I then welded flat steel plates to one end of 8" long pieces of 1'4" threaded rod and riveted them to the other end of each strap. Each clamp is completed by inserting each rod through holes drilled at the other end of each 2 x 4 and held in place by large washers and nuts. These clamps can be used to secure the lead­ ing edge material to either the form blocks or the wing panels. Care must be taken to not over-tighten the clamps and damage the leading edge material. Good clamping pressure can be at­ tained by positioning the clamps over ribs about 18-24" apart. During most restoration projects it is necessary to make some repairs. These should always be made in accor­ dance with the FAA manual, "Accept­ able Methods, Techniques and Prac­ tices - Aircraft Inspection and Repair," FAA AC No. 43.13-1A. This manual is generally referred to as "Part 43" and it should be a mandatory addition to every restorer's library . •

Wayne Smith and his beautiful green and yellow Cessna C-37 Airmaster.

REBIRTH OF AN AIRMAS1'ER

by John A. Young Some people would have been con­ tent if they'd spent hundreds of hours, and many dollars, to restore an antique aircraft from a "pile of junk" state to award-winning condition. For D. Wayne Smith (EAA 133326, NC 7590) , of Maricopa, California, however, com­

pleting work on a World War II Stear­ man PT-17 trainer in early 1980 was only the beginning . Smith, a construction contractor, re­ cently put the finishing touches on his second restoration project, a 1937 Cessna C-37 Airmaster, NC18599, SIN 384. The aircraft didn't look like much

Hauling· home the new purchase. 12 AUGUST 1986

when Smith bought it in DeKalb, Illinois in November, 1980. The skeleton of the aircraft had no engine, since the owner needed it for another plane he was re­ building. The wing had been destroyed during restoration , and a lot of other hardware was also missing. Enroute back to his home southwest of Bakersfield with the remains of the

Wayne Smith used two tons of sand in sandblasting the fuselage and other metal fittings.


Cessna on a trailer, Smith said a ser­ vice station attendant misunderstood his request for directions and, looking at the trailer load, issued directions to the local dump! Building a new wing to Cessna specifications was a major undertaking, requiring about 1,700 hours of Smith's time. He estimates he put in five hours building each of the ribs in the tapered cantilevered wing . Smith used 500 board feet of aircraft­ grade Sitka spruce for spars and ribs of the wing . There are no struts connect­ ing the wing to the fuselage, and in an effort to convince doubters of the strength of the structure in the 1930s, Cessna officials took a picture of 23 men sitting on top of an Airmaster's wing . Smith learned that Airmasters had several different wings. "I did not know that the chord was changed until I had finished the wing . This required a change in the fuselage top deck. Ribs were built from a 1/16-inch plywood web with 2-3/16 inch spruce caps glued and nailed on each side." The 34-foot spars were most difficult to build, he said. "I spent about 10 days trying to figure a method for mass-pro­ ducing scarf jOints (about 40 were re­ quired). A jig on my 6-inch jointer pro­ duced a beautiful joint in about 15 min­ utes." Over eight gallons of resorcinol glue was used in the spars and ribs . A router and SkiI-Saw was used to shape the five tapers in each wing . The 1/16-inch plywood for the covering of the wing leading edge, center section and tips was scarfed, soaked and fitted . Truck tarp elastic tie-downs were used to hold the leading edge ply during shaping and gluing. The Warner engine, which came from the remains of a Fairchild 24 which Smith bought just for the engine "ap­ peared to be good", when purchased. Upon disassembly, however, it was found to be mostly junk. It was com-

pletely overhauled with many parts being hand-chromed back to specifica­ tions. Most Warner engines did not have generators, and Cessna, since the Air­ master had no wing struts for securing a wind-driven generator, imbedded it in the leading edge of the right wing . "It makes an unusual noise when turning ," Smith notes. The aircraft engine mount is integral with the fuselage frame. There are no rubber shock mounts, so the engine vib­ rations are transferred to the fuselage and cause a slight vibration during flight. The Airmaster was built for speed and former owners include such nota­ bles as actor Robert Cummings. The cowl was badly cracked and bent when Smith bought the plane. Large pieces were cut out and new soft aluminum patches were Heli-arced in. Much filing and hammering with sandbags and blocks formed a good cowl. Small imperfections were filled

with epoxy thickened with flox. Of all the parts which went into the plane, the only one available new was the plexiglass windshield . The complete instrument panel was built exactly as the original and one of the most difficult parts to find for it was the 1936 Ford fuel gauge. Smith calls the "Johnson Bar" brake a "real widow maker." The brake was built from Cessna drawings. The brakes are mechanical and work through a lever having a thumb button to engage a ratchet. With the lever full forward, full rudder is available. With the lever part way back, differential wheel braking comes in on the rudder pedals with only partial rudder. Full back on the lever sets the parking brake. 'This system requires one more hand," he said. On rollout the stick must be held back between the knees while the pilot is still working the rudder ped­ als. The tail wheel is held straight by a 3/8

inch bungee cord . When turning , the brakes must overcome the bungee cord in order to turn . Some other examples of the cost of rebuilding the plane include: • Smith used 14 4-by-8 foot sheets of mahogany plywood for wing skins and ribs ; • Two tons of sand was used for sandblasting the fuselage and parts ; • Over $450 was spent for all new bolts and fasteners ; • . The plane was painted original green and yellow colors, especially mixed ; • The plane was covered in original aircraft cotton with a butyrate finish on fabric and acrylic enamel on metal ; • All wood formers-stringers in the fu­ selage and all wood in the "tail feathers" was replaced ; Wheel pants were optional on new air­ craft.

laminated birch. Smith estimates he put about $25,000 into the project. Smith's airstrip is 1,800 feet long and 100 feet uphill. This did not allow any taxi test. The close cowl and baffling did not allow much engine run-up without overheating. "Once I was satisfied that the engine and airframe were satisfac­ tory - I flew it," he said. "There were no problems, except that it flew in a skid . The rudder had no cutout for a trim tab and I found out later that the tab was surface mounted . After instal­ ling a rudder trim tab, it became a good flying airplane." Airmasters have three different types of flaps - belly, spoiler and trailing edge. Smith 's plane has the trailing edge type , operated by an electric motor through worm gears. When de­ flected , they slow the plane about 10 mph. Smith put in a lot of seven-day weeks working on the project. "I love this kind of work, " he said. He looks forward to taking the plane to fly-ins where the

work he has put into the project will be appreciated. The Airmaster is a rare bird these days. Smith estimates there are only four of the craft flying on the West Coast, and only about 20 across the United States. The four-place plane could be confi­ gured as a seaplane and they were also popular when used in aerial photo­ graphy in the 1930s and '40s because of their versatility and affordable price tag. Mounted with a Fairchild Aerial Camera, Airmasters could fly to 18,000 feet. "This rebuild would have been impos­ sible without the help of many people, especially Bob Pickett, historian at Cessna Aircraft, who with Airmaster ex­ pert Bill Koellig of Great Bend, Kansas, provided original plans and many words of encouragement," he said. A flyer since 1939, Smith is a former Industrial Arts teacher at the Maricopa High School. .

First CPA Fly-In

The first ever fly-in of the Cessna Pilots Association was held this past April 18-20 at Concord, California and it was an unqualified success. Over 300 members, spouses, friends and CPA staff gathered at the Sheraton Inn on the Concord Airport for a weekend of fun, fellowship, education and Cessnas. Members' planes totalled over 160. The seminar programs drew the biggest crowds with three seminar rooms running continuously during the day. Other activities included exhibitor displays, cocktail parties, banquets and tours, for example, to Fisherman's Wharf in San Francisco. One of the most enjoyable activities was the individual model forums. This allowed all the owners of one model of Cessna to gather together and share ideas, information and experiences among themselves. During the Saturday night banquet it was revealed that the Cessna Pilots As­ sociation is actively pursuing the estab­ lishment of an educational and techni­ cal center for the use of the member­ ship.

Oshkosh Attendees

Once again the Cessna Pilots Associ­ ation will have a hospitality tent for the exclusive use of CPA members, their families and guests. This provides each member with a base of operation during the Convention, including a place to sit down out of the sun, get something to drink without standing in line, store packages, leave messages for others

and seek CPA staff help with any prob­ lems. The tent is located in the outdoor exhibit area near the EM B-17 and across from the Cessna Factory exhibit. For information on the CPA, contact John M.

A recent newsletter of the Taylorcraft Owner's Club reports that one of their members, Dr. Chester Peek of 1813 Danfield Drive, Norman, Oklahoma 73069 is writing a biography of Mr. C. G. Taylor. Over the past year he made some progress with some fine help from Ken Tibbets who was with C.G. from the very beginning in Bradford, Pennsylvania. Dr. Peek is requesting that anyone with information about Mr. Taylor, the factory(ies) , experiences with the airplanes, pictures, articles, etc. which could be loaned to him for the book, please do so. He will copy and return anything you want back. Dr. Peek has owned a beautifully restored Taylor E-2 Cub for many years . For information on the Taylorcraft Owner's Club, contact Bruce "Barney" Bixler, 12809 Greenbower, N.E., Al­ liance, OH 44601 .

Most Piper owners of the subject air­ craft should have received Piper Ser­ vice Bulletins no. 819 (fuselage door frame tube corrosion - J-4, J-5, PA-12, PA-14) and no. 1570 (lift strut fork in­ spection/replacement-revised - J-2, J-3, J-4, J-5, PA-11 , PA-12, PA-14 PA-18, PA-19). Piper considers compliance mandatory. Cub Club members not re­ ceiving copies of these can receive same by sending $1 to the club. This information is particularly important for those in the process of rebuilding an aircraft or planning to do so. Clyde Smith, Jr. notes that the J-3, PA-11, PA-18 and short wing Pipers aren't even mentioned on Service Bulle­ tin no. 819, yet they are also guilty of the rust problem. The June/July 1986 issue of "Cub Clues", the newsletter of the Cub Club, includes an article by Clyde in which he describes a method of inspecting and identifying the prob­ lem. These two bulletins pertain to critical safety measures and owners of a/l Piper models mentioned above should be aware of them and take appropriate ac­ tion .

that paper clip. Do the paper clip tests and you will be determining the 'endur­ ance limit' and the 'notch sensitivity' to the number of flexes or 'stress rever­ sals' applied before failure and you can draw 'S-N diagrams' of the clip in its original condition, as bending a new clip once, then continuing to flex it slightly. You would find the overstressing to have greatly reduced the endurance limit. "Most of the stressed parts of post­ war Aeroncas are made of 4130 steel. The S-N Diagram (see Fig. 1) for this steel was established by test long ago, and you can be sure this diagram was used when your Aeronca was designed . Keep in mind, the numbers for the dia­ gram were generated under laboratory conditions, using new, perfectly machined test bars and represent the BEST the material can be expected to do. "Figure 1 shows how I can flex a 4130 steel paper clip (or wing strut or engine mount or main gear leg) millions of times if I load it to less than 43,000 pounds per square inch (psi) of cross section available. At this stress level an engineer would call the anticipated life 'infinite.' But if I increase the load only 16% to 50,000 psi, the diagram shows I can expect the part to fail in about 50,000 load cycles. Fatigue failures are sneaky. InCipient cracks are almost al­ ways invisible to normal inspection. The final failure occurs with disastrous sud­ denness. "Good designers, like those at Aeronca, work down on the flat part of the S-N diagram, putting in some cush­ ion as a safety factor. An airplane de­ signer can't get carried away with a lot of cushion, though. The airplane would quickly become too heavy to perform well. So he designs near the endurance limit for normal duty and counts on the sloped part of the S-N diagram to keep the wings on during the occasional overloads (read 'overstress') imposed by hard landings, severe turbulence , or operation over gross weight. "The Aeronca designers did such a superb job of producing optimum

airplanes, combining strength and light weight to get machines that could be expected to last indefinitely if properly operated and maintained .. . and yes, there's the rub!

"Overstress and corrosion drastically lower the line on the S-N diagram. Look through the logs on your Aeronca (if you are lucky enough to have all of them) and imagine all the opportunities she has had for being overstressed while on duty as a trainer or an ag-plane. How about the time the pipeline pilot hooked a wing while trying to out-turn a coyote and cartwheeled her through the sageb­ rush? Sure, she was rebuilt 'good as new'. You betcha. The typical Aeronca has taken a tremendous beating. You may not really know how severe or fre­ quent the beating has been or how well repaired. "Everyone knows corrosion is bad, but most assume if the surface rust is removed or if an ice pick won 't go through a wing strut, the airplane is as 'good as new'. Sorry, but the assump­ tion is wrong . "Corrosion creates 'stress risers'. If you are not familiar with the concept of stress concentration at a stress riser, study Figure 2 a bit. Picture the stresses in a part as a flow of water through the section. You want the water to flow as smoothly as possible with no obstruc­ tions to cause turbulence or back the

water up. You can see how a corrosion pit is like a rock in the stream, concen­ trating and confining the flow. In effect, the part is working at higher stress level farther up on the S-N diagram where it takes fewer cycles to break it. "Removing rust can slow further dam­ age, but nothing can restore the ORIG­ INAL strength of the part. How much is the part weakened? It depends on how many pits and how deep they are. "Is the message getting across? Your Aeronca is NOT as strong as it was when new. There is no such thing as a 'just like new' Aeronca, unless EVERY piece of original material has been re­ placed. Am I saying old airplanes are not safe? Of course not, but only the best of maintenance and thorough fre­ quent inspection can keep them safe. Don't expect them to tolerate the loads they would take when new. Just be­ cause you survived snap-rolling a Champ in 1946 does NOT mean you will survive the same maneuver today. Both the Champ and YOU have spent a lot of time high on the S-N diagram and accumulated a lot of overstress since 'Give 'em Hell Harry' was in the White House!" •

(Airworthiness Directive) by Paul H. Poberezny

For those of us operating aircraft equipped with Hamilton Standard pro­ pellers in accordance with FAA Airwor­ thiness Directive AD81-13-0oR1 , it has, from the very beginning, become a very big expense. It has resulted in the loss of aircraft use and, in many cases, necessitated the removal of the propel­ ler and trucking it to one of the relatively few propeller shops (considering the size of the USA) for compliance. The AD, as we have heard, was the result of the Hamilton Standard Propeller Company's recommendation and our petition to FAA as the result of a propel­ ler blade failure . . . not much to go on considering the many, many thousands of fine Hamilton props in operation. It was stated that severe corrosion was the cause of the failure which we believe to be a very rare occasion. We assume that liability upon the manufac­ turer was the inducement to persuade FAA to act. The point could be argued that a one-time inspection was war­ ranted to gather factual data as to the integrity of the propeller, and to ac­

cumulate data to determine how realis­ tic the problem really is. However, it has been most difficult to obtain information from propeller overhaul or repair facilities regarding corrosion or other problems they find during inspection. About the only statement they will make is that the AD was complied with. Some propeller shops have been reported as saying they will not comply with the AD unless they overhaul the propeller. This results in a much greater expense and the length of time the aircraft is out of service. The inspection interval between AD compliances varies within the many FAA regions we deal with. Opinions by FAA personnel vary in giving time ex­ tensions, and many FAA folks are ex­ pected to become propeller experts with little or no background on the subject. I have approached FAA at the Washing­ ton level on this matter, but with few facts in hand other than the history on our own Museum aircraft, it is not enough to warrant sufficient interest or concern by FAA. If I had sufficient infor­ mation and findings as to the amount of

corrosion found, or not found, from you users, the FAA would be receptive to reviewing the situation. I feel that if you pay a certified propel­ ler repair facility for the inspection and compliance with the AD, then you are entitled to a written statement as to what airworthiness deficiency was found, if any, during inspection in com­ pliance with the AD. How else will we be able to gather data in order to evaluate this AD? Here at EAA Headquarters I will need propeller make and model, time of oper­ ation in hours, the number and dates of compliances of the AD, as well as a list of discrepancies (if any) found during these inspections. Without your cooper­ ation and this data, we will continue to add to the expense of operation, the loss of use of the aircraft, and possible damage incurred while trucking these large propellers hundreds of miles to and from repair stations. These are in­ conveniences that aircraft owners should not have to endure. Please write to me personally ~t EAA Headquarters.• VINTAGE AIRPLANE 17

BE III MOIEl 52

by Mark Savage

Two years ago, while visiting my father and step-mother in Florida, I met a man named Vern Biasell, an aeronau­ tical engineer who had worked on some of history's more enduring and interest­ ing aircraft. Last March I went back to Florida and spent the better part of an evening talking with Mr. Biasell about some of the famous airplanes he'd worked on. However, one airplane he worked on never got past the prototype stage. This attractive and innovative bird captured my attention : It was the Bendix Model 52. Mr. Biasell had begun aircraft design and engineering for the Stinson Aircraft Company in 1937, working for a Mr. Athanas (Jack) Fontaine. Mr. Fontaine was Chief Engineer at Stinson at the time and had been responsible for the Voyager series. Mr. Biasell was project engineer on the Reliant and later the L-5, and as we talked, Biasell took a moment to reminisce about the "Sen­ tinel." According to Mr. Biasell, in 1940 the Army was in the market for an observa­ tion plane. They had written specs and were starting tests on several pro­ totypes supplied by competing aircraft companies; Stinson's entry was the 0­ 49, later known as the L-1 . However, some engineers at Stinson believed the Army was asking for an airplane that was too large and expensive for its in­ tended purpose. As a result, a request was made to top management for ex­ penditure of company funds to demon­ 18 AUGUST 1986

strate their engineering concept. Au­ thorization was given and with Vern Biasell as project manager, a demon­ stration prototype was built and flown just 28 days later. It was highly success­ ful and shown to the Army during the 0-49 flight trials. Army interest was aroused in this "flying jeep" version of an observation plane, which became the famous L-5, and production began. Mr. Biasell was involved in other in­ teresting projects during the war, but as the conflict drew to an end, many com­ panies and aircraft designers looked forward to the post-war period. At the end of the World War II , market surveys indicated that a two-place, all-metal re­ tractable aircraft would sell briskly in the anticipated post-war aviation boom. The Bendix Corporation, like many other businesses, made plans to build and market general aviation aircraft to fill the proposed needs of the many mil­ itary pilots who were soon to return to civilian life. Mr. Jack Fontaine was hired from Consolidated-Vultee to head the new Bendix Aircraft venture along with Mr. Biasell, who was then at the Gen­ eral Motors Research Laboratories. Designed in July 1945, the Bendix Model 52 prototypes were engineered by Mr. Biasell and built in 1945-46 at the Bendix Experimental Engineering Department at 261 McDougal Street in DetrOit, Michigan. The Model 52 was a low-wing, all-metal airplane with side­ by-side seating and retractable tricycle landing gear. Wing span measured 33' 3"; length 22', with an empty weight of just 1043 pounds. Target price was

$3,900, and the means by which Bendix and Biasell intended to meet that price is intriguing. What should make the Model 52 in­ teresting both to home builders and those interested in vintage/antique airplanes is that Mr. Biasell designed the Model 52 to use automotive-style high production techniques. These techniques not only lent themselves to economic mass production, they also kept the weight low without sacrificing structural integrity. Figure 1 illustrates the difference in design between the Biasell/Bendix Model 52 (top) tail feathers and those of a conventional aircraft. Note that both horizontal stabilizers and the vertical fin are identical ; one piece can serve as either stabilizer or fin . And , not including the skin, each unit totaled just 12 parts! The fuselage was designed along the same lines (Figure 2) , and used rolled skin to form the stringers. But perhaps the most interesting part of the design was that of the wing . As shown in Figure 3, the wing consisted of two spars, 7 ribs set at 45 degree angles to each other, end cap, aileron and flap assembly and leading edge for a total of 19 parts per wing , not including the skin or landing gear/retracting mechanism. The wings used a modified Goettingen section, up-swept at the trailing edge to flatten the stall curve . According to Mr. Biasell, the airplane was virtually spin proof. Moreover, it had very gentle stall characterisitcs and maintained aileron control throughout the stall. The Model 52 could be flown

at very high angles of attack without dropping a wing or surprising its pilot with an abrupt stall. An article on the Bendix Model 52 in the September 1971 issue of "The Great Lakes Flyer" notes that the 52 had "full length ailer­ ons (that) could be 'drooped' to serve as landing flaps which reduced the stall speed ... from 53 mph to 47 mph.," a highly imaginative design feature for a general aviation production aircraft. Figure 4 illustrates the method of pro­ duction that had been proposed. The rear fuselage, wings, engine cover and cockpit areas were to be built as sepa­ rate units, then joined to the "keel" at the end of the assembly line. The cab was to be lowered onto the assembly just as automobile bodies were lowered onto frames in automobile assembly plants. The other picture shows the clean lines of the Model 52, long wing , and outward retracting gear. It was powered by a 100 horsepower Franklin, and, ac­ cording to Biasell, had a maximum speed of 154 mph . It cruised at 140 and climbed at 900 fpm . The original design called for a six-inch propeller hub exten­ sion shaft which gave the plane a more streamlined appearance. But later, to reduce manufacturing costs, the exten­ sion shaft was eliminated and the nose of the Model 52 took on a more conven­ tional appearance. The shorter nose also reduced the maximum airspeed to 148 mph, which was the maximum speed indicated by the "Great Lakes Flyer" article. The first Model 52, NX-34110, was flown by Bendix Chief Test Pilot AI Schram in December, 1945, just five months after the first design sketches were laid down. The prototype had

been trucked across the Detroit River to Windsor Airport in Canada for the flight. Biasell noted that the Windsor Air­ port was chosen because it was close by and offered a degree of security against the press and competitors. By September, 1946, two other prototypes were built and the Model 52 had com­ pleted all but the final flight tests for an Approved Type Certificate. Several hundred tool makers were working on production tooling when a change of Bendix's top management abandoned the personal aircraft field . The new management worried that a successful Model 52 would make Ben­ dix Corporation a competitor of other airframe manufacturers who were cus­ tomers of Bendix's other divisions. Ac­ cordingly, management decided that situation might hurt sales in those other departments, and so in September the board of directors announced that the Aviation Department had to be dis­ banded. The prototypes were stored for six years and then donated to the Uni­ versity of Michigan, Wayne State Uni­ versity, and the Detroit Aero Mechanics High School.

The aviation community obviously lost out on an innovative and interesting airplane when Bendix's top manage­ ment decided to abandon the Model 52 ; it was an attractive machine and offered a high level of performance for its time . However, in light of the post-war gen­ eral aviation fizzle, abandoning light air­ craft manufacturing was probably a wise business decision. But just lookng at these pictures and talking with Mr. Biasell about the design features and production techniques of the Bendix Model 52 made me wonder if these ideas aren't worth a second look. It would be a shame to forget this interest­ ing machine .. . and the innovative and futuristic production techniques inher­ ent in the design. During the time the two Bendix Model 52's were undergoing flight tests, two­ four place aircraft were being designed and built. Known as the Model 51 and 51A, they were all-metal, twin boom pushers with retractable tricycle landing gear. Maurice Mills 12th from the left in the photo of the Bendix Aviation Depart­ ment, was Chief Engineer for these planes. Mr. Mills had worked with Stout, the designer of the Ford Tri-Motor. Later he worked at Stinson and after the war, of course went to Bendix. Construction of the pushers was simi­ lar to the Model 52: the wings were of diagonal rib design and employed the same modified Goettingen airfoil (Ben­ dix 416 airfoil) section. And like the Model 52, automobile-type assembly line techniques were to be used to build the planes. This would make it possible to economically build either a landplane or amphibian from the same basic air­ frame: the upper fuselage could be joined to either type of lower fuselage during assembly because except for the lower fuselage, wingtip floats and longer landing gear of the amphibian,

the major assemblies for the two aircraft were identical. Only one of each type was built. The landplane was flown for approximately 25 to 30 hours (Biasell's estimate) at the Willow Run Airport at Ypsilanti , Michigan. The amphibian was never flown ; only preliminary taxi tests were conducted. The hull was developed, and hydrodynamic characteristic tests conducted , with models at the Experi­ mental Towing Tank, Stevens Institute of Technology, in Michigan. Both the landplane and amphibian were powered by a 6 cylinder Franklin engine which developed 220 hp at 2,600 rpm. The design statistics are as follows : Landplane (Model 51) Design Max Speed . . . . . . . . . . . . 168 Design Cruise Speed . . . ....... 157 Design Stall Speed . . . . . .. . ... 53 Wing Span .. ....... . . . . .. .. 40 ft.

As Mr. Biasell put it in his note to me "(this) is a little of the very meager infor­ mation available. Basic tests were so preliminary (when the decision was made to cancel the aircraft program) that no decisions on the future of these designs had ever been formulated ." Like the three Model 52's, after pro­ longed storage (6 years), both airplanes were given to universities for student in­ struction purposes .•

The newly restored 1929 sailing glider. The machine was invented by a WW I French pilot.

The sailing glider as it appeared when found at Old Orchard Beach, Maine. 22 AUGUST 1986


By Steve Cartwright Assistant Director Owls head Transportation Museum Owlshead, ME 04854 For every invention that works , there must be many that have failed . Of course, the inventor doesn't brag about the flops, even if they did get off the ground. But one such magnificent mis­ take has been preserved. A zany, one­ of-a-kind flying machine with a Maine heritage is on exhibit at The Owls Head Transportation Museum. Restored to flying condition at a cost of $20,000 is a 1929 motor-less sailing glider. It was actually flown a number of times at Old Orchard Beach in 1930, but apparently with less than unqual­ ified success. The glider was disman­ tled and stored in a large box until a few years ago, when it was found and do­ nated to the Museum. The designer-pilot of the strange craft, apparently a John Domenjos, dropped from the public eye shortly after the trials at Old Orchard . Oddly, the sail ing glider - sort of a marriage of a sloop and a plane ­ achieved a certain fame when it ap­ peared as the cover illustration on the August 1930 issue of Popular Mechanics. But the magazine failed to say who built the plane. A brief film clip , although blurry, shows the sailing glider taking off from the sands at Old Or­ chard , and for a few minutes it is air­ borne, sails flapping. The glider pilot had to be a combina­ tion sailor-aviator, with a dash of the daredevil thrown in. The Museum is hopeful that someone may come for­ ward with more information concerning

For a photo session, the glider was allowed to roll outside the Museum, pushed playfully along by the breeze, but volunteers seized the craft before it could travel very far along the aban­ doned airport runway ; too much was at stake.

LEGACY OF'~T

nINGS

Another new addition to the EAA Video Aviation Series is "Legacy of Wings", the story of Harold Frederick Pitcairn, an American aviation pioneer, whose efforts and accomplishments are reflected in many facets of aviation today. As a young boy he was fasci­ nated with manned flight and in his teens was designing, building and flying model airplanes, including a delta wing . He took flight training at one of Glenn Curtiss's flying schools and later with the Signal Corps during World War I. His first airplane was a Farman Sport biplane which he flew from the family farm . The farm, near Bryn Athyn, Pennsylvania, became the original Pit­ cairn Field in 1924, and when it was dedicated, some 20,000 spectators showed up to witness the festivities. That same year, Harold Pitcairn in­ formed his wife that he had made the decision to make aviation his career. A quiet man, Pitcairn shunned the spotlight but he worked tirelessly to im­

prove both the scope and safety of avi­ ation. His series of Pitcairn Mailwings were great improvements over the machines being flown by airmail pilots. Pitcairn started his own airline which became one of today's major carriers, Eastern Airlines He was intrigued with rotary-wing craft and traveled to Europe to meet Juan de la Cierva who had made rotary-wing flight a reality. In time, Harold Pitcairn developed his own rotary-wing craft and his patents, which date back to 1926, were pur­ chased by Igor Sikorsky and incorpo­ rated in the XR-4, the world's first helicopter. This video includes rare, historic foot­ age from amateur home movies show­ ing flights of many Pitcairn aircraft in­ cluding autogiros landing and taking off.

It was fitted with four Bristol Pegasus X.C. en­ gines and saw service with RAF. 201 and 422 Squadrons during that year. In February, 1945 it was returned to Short for conversion to a Sunderland Mk. V fitted with P&W Twin Wasp R­ 1830-900 engines. From April 1945 to February 1946, it served with 330 Squadron. In November 1946 it was placed in long term storage, ending in May 1952 when it was again returned to Short for mod­ ification to New Zealand standards. In May 1953 it was delivered to the Royal New Zealand Air Force as SIN NZ-4108 and flew with NO. 5 Squadron (M.R.). In 1963 it was acquired by Ansett Fly­ ing Boat Services in Australia and con­ verted to passenger configuration. The front gun turret was removed and the resulting "nose job" left a more promi­ nent bulge than a Belfast-built Sandrin­ gham resulting in the converted aircraft being referred to as a Sunderingham! Up to this time the aircraft had only flown a total of 1085 hours. From De­ cember 1964 until the termination of An­ sett's flying boat services in September, 1974, it operated on the company's route from Rose Bay, Sydney to Lord Howe Island, a distance of about 400 miles, registered VH-BRF in Australia under the name of "Islander". Bought in September 1974 for Antil­ les Air Boats in the Virgin Islands by Capt. Charles Blair and re-named "Ex­ calibur VIII," it was flown to Puerto Rico via Pago Pago, Honolulu, Long Beach, Eagle Mountain Lake, Washington, New York, Boston and St. Croix (a total of about 9,900 miles). After its arrival in Puerto Rico the air­ craft was stored at Isla Grande Airport, San Juan until May 1979. After the death of Charles Blair the flying boat was saved from certain destruction by the millionaire, Edward Hulton. Hulton spent more than $1,000,000 in making the boat airworthy, and on November 12, 1980, Blair's widow, actress Mau­ reen O'Hara christened the aircraft "Juliet" and it was registered N158J. The Sunderland is now in England, arriving there on May 19, 1981 flying from Puerto Rico via St. Croix, Ber­

muda, Gander, Shannon and Calshot. Recently, "Juliet" has acquired British registry, G-BJHS. British Short Sunderlands were origi­ nally passenger-carrying flying boats, converted during WW II to reconnais­ sance service including maritime con­ voy escort and anti-submarine warfare. Sunderland production continued until 1945 reaching a total of 741 .

The accompanying photos are of the last two flyable Sunderlands. VP-L VE is in a Museum and N158J (now G­ BJHS) is flying in England. Short Sunderland specifications: wing span 112' 9", length 86' 3", height 32' 10-1 /2" , max. take off weight 59,000 Ibs. , cruising speed 140 knots, max. passenger seating 42 and crew 5. •

Cavalcade ofWiV\9I--s_

The size of the unidentified aircraft can be judged by the men in the photo.

by Gene Chase (Photos courtesy Museum of New Mexico) The Cavalcade of Wings is a collec­ tion of scale models of the aircraft which have been of significance to the aviation history of Albuquerque, New Mexico. Over 500 models are currently on per­ manent display while the master list contains 790 names. This collection is in effect a miniature museum. Each model has the livery, numbers, etc. of an actual aircraft used in Albuquerque. The accompanying photos are three of seven donated to the Museum of New Mexico circa 1950 by someone in Albuquerque . The folks at the Caval­ cade of Wings are attempting to deter­ mine if the aircraft was actually built in that city. Inscribed on the back of two of the prints is "Albuquerque 1910­ 1912". To date no one has been able to identify the people or the buildings. A long time resident and historian once said that he remembered a strange aircraft being built by two black draymen. The people in the photo do not appear to be black. Mr. Harry M. Davidson of the Cavalcade of Wings 26 AUGUST 1986

feels that if the statement is true and this is the machine, it could be the first aircraft built by a black man. If any members can identify the air-

craft, people or location they are asked to contact Mr. Harry M. Davidson, Cavalcade of Wings, 1408 Jefferson, N.E. Albuquerque, NM 87110.

Three-quarter front view shows the forward elevator apparently positioned downward by moving the pilot's control wheel upward. The five cylinder radial (rotary?) engine is behind the pilot's seat. The aft rudder was possibly controlled by rotating the control wheel.


This rear view gives an idea of the planform of the machine.

MEMBER'S PROJECTS ...

by Gene R. Chase This Laird LCR-W450, SIN 162 (shown at right) is being restored to original configuration by a father and son team in Zanesville, Ohio. In the rear cockpit is the father, John Morozowsky (EAA 79439, AlC 2221). Son Anthony (EAA 246668) is in the front 'pit. Anthony says that E. M. "Matty" Laird made only two of this model. It is pow­ ered with a 450 hp P&W Wasp and was issued a Group 2 approval number 346 on 5-19-31 (see Joseph Juptner's U.S. Civil Aircraft, Volume 9, page 161). Matty claimed the plane could attain 200 mph with the front cockpit covered . The Morozowsky's are also restoring a 1928 Laird LC-1B-200, SIN 161 pow­ ered with a 9-cylinder Wright J-5. The only full-size example of a Bristol Scout in the world is this replica built by Leonard E. Opdycke (EAA 1076, AlC 6933), 15 Crescent Road, Poughkeep­ sie, NY 12601-4490. The accompany­ ing photo shows the plane at Cole Palen's Old Rhinebeck Aerodrome near Rhinebeck, New York. Leonard began cutting pieces of the Scout about 20 years ago, but the ac­ tual construction took about five years. The first flight of the 1914 Bristol Scout o took place in July 1984 and lasted about 25 minutes until the magneto failed. Leonard was unable to glide back to Old Rhinebeck and was forced to land in the trees. The Scout suffered

28 AUGUST 1986

some damage but fortunately the pilot was not injured. This past April Leonard received what probably is the highest amount of praise an airplane builder and enthusiast can receive. Representatives from Britain's Royal Air Force Museum took his disas­ sembled Scout to London. It has a place in their history because it was one of the first British armed airplanes. About 374 Bristol Scouts were built between 1914 and 1916. Many were used as sport planes, but the British Royal Flying Corps mounted guns and used them in combat during WW I.

Leonard built the Scout from draw­ ings he obtained from the Bristol Aero­ plane Company and powered it with a nine-cylinder LeRhone rotary engine of 80 hp. Because the museum in London has several examples of the engine, they took only the airframe. Although Leonard Opdycke no longer has his Bristol· Scout, he is still deeply involved in aviation as publisher and editor of World War I Aero, a magazine for early airplane enthusiasts. This ex­ cellent publication has a world-wide cir­ culation and each issue is truly a collec­ tor's item . •
