Airworthiness Directives; Airbus SAS Airplanes

FAA / Federal Register · 2021-25534

The FAA is adopting a new airworthiness directive (AD) for all Airbus SAS Model A350-941 and -1041 airplanes. This AD was prompted by a report of a broken forward guide arm found during a passenger door emergency opening test. Investigation results indicated that the opening speed of the door was higher than expected, likely caused by a reduced damping due to oil leakage of the passenger door damper emergency opening actuator (DEOA). This AD requires repetitively replacing certain forward and aft guide arms on the passenger door, inspecting the forward and aft guide arm support brackets for damage, modifying certain DEOAs, and repairing damage if necessary, and also provides an optional terminating action for the repetitive replacements, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
