WhensurplusRoyalAirForceChipmunks werefirstreleasedontothecivilmarketin1956, privateownersandflyingschoolssoonfound thattherewasmoretocivilcertificationthan paintingonaG-registrationandapplyingfor aCertificateofAirworthiness.Atthattime,the onlyvariantofChipmunkapprovedbytheARB (predecessortotheCAA)wastheMk21,from whichthemilitaryTMk10differedinanumber ofdetails.
