In this case is always (5, /R/ (%Ca) < 0 hence no weight adjustment and balancing are made. However it is necessary to enclose to the initial balance protocol a protocol which must comprise the characteristic of the carried out repair and the corresponding changes of the weight characteristics of the repaired aileron:

If t h e aileron has been statically overbalanced before the repair ( G a (0): and if it is possible to determine 1 reliably the weight increment A G ~(kg) i and the perpendicular distance of the centre of gravity X R (m) from the axis of rotation (either before the axis of rotation@, or behind the axis of rotation 8 then procede as follows:
