Unsafe Condition
Failure of the generator drive gear retaining nut internal tooth lockwasher (CMC P/N 531232) could occur.
AI-generated summary from the source AD text. Verify against the official source before acting.
Required Actions
Remove the generator and inspect the generator drive to determine if the internal tooth lockwasher or plain flat washer (CMC P/N 401507) is installed. If the internal tooth lockwasher is present, remove it and install the flat washer. Use a new retaining nut (CMC P/N 531231, Esna P/N 29NTE-064 or equivalent) and apply a torque of 175-195 inch-pounds to the nut.
AI-generated summary from the source AD text. Verify against the official source before acting.
Compliance Time
Compliance required at next periodic inspection, engine overhaul or generator removal whichever occurs first, but in any case not later than December 31, 1960.
