Details of the Boeing 767 AD Alert

The FAA issued an AD to detect and correct flap rotary actuator gear disengagement from its mating reaction ring.

With flaps extended, this disengagement can cause:

    • Uncommanded roll due to flap blowback
    • Overload
    • Flap departure from the airplane

These issues could compromise safe flight and landing of the airplane.

The AD requires an inspection of the fixed ring gear. Because of corrosion, the ring gear has to be scrapped. Airlines would need to invest $20,000 or more for a new fixed ring gear per actuator.
