Summary
The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 777-200, -300, and -300ER series airplanes. This proposed AD would require replacement of the gimbal plates of the left and right outboard trailing edge flaps with improved gimbal plates and other specified actions. This proposed AD results from a broken pivot link found on the inboard support for the outboard trailing edge flap. We are proposing this AD to prevent disconnection of the drive arm from its drive gimbal, due to a broken pivot link on an outboard flap support, which could result in unexpected roll of the airplane and loss of control of the airplane.
