The airworthiness directive
56-04-01 CHAMPION: Applies to Model 7EC Aircraft, Serial Numbers 300 to 370 Inclusive.
To be accomplished as soon as practicable but not later than April 1, 1956.
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. If a standard AN bolt, nut and washer are installed, replace 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.
