48-39-01 AERONCA: Applies to All Model 7 Series Aircraft.
To be accomplished as soon as possible but not later than November 1, 1948.
Inspect front and rear control stick socket castings, P/N 2-705, for cracks at the ears to which the push-pull tube attaches. If found cracked, the castings should be replaced. To prevent future failures the bolt, nut and washer now installed are to be replaced with a clevis bolt, AN 24- 16 (11/16 grip) and an AN 320-4 shear nut so that excessive loads cannot be placed on the socket ears.
