Airworthiness Directive 2021-08-08
one-timeAirworthiness Directives; Airbus SAS Airplanes
What this AD requires
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 that a welding quality issue has been identified in the gimbal joint of the air bleed duct located at each wing-to-pylon interface; the inner ring of a gimbal had deformed to an oval shape, which could lead to cracking caused by direct contact between metal parts. This AD requires replacing affected bleed duct assemblies and bleed gimbals at the wing-to-pylon interface with a serviceable part, 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.
Which aircraft AD 2021-08-08 applies to
Whether AD 2021-08-08 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
