Summary
This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Airbus Model A330, A340-200, and A340-300 series airplanes. This proposal would require replacement of flap rotary actuators with modified flap rotary actuators. This action is necessary to prevent fatigue failure of the rotary actuator lever for the flaps, which could result in loss of the flap surface and consequent reduced controllability of the airplane. This action is intended to address the identified unsafe condition.
