Description

The FAA proposes a new airworthiness directive (AD) for all Airbus SAS Model A350-941 and -1041 airplanes due to mechanical overloads on certain primary flight control actuators during acceptance testing. The AD would require replacing affected parts with serviceable ones and prohibit installation of affected parts to address potential actuator failure and loss of airplane control. Comments on the proposed AD are due by May 18, 2026.
