Models named: A350-941, -1041. Read the applicability below — it usually turns on serial or part numbers too.

Applicability*9

This AD applies to all Airbus SAS Model A350-941 and -1041 airplanes, certificated in any category.

Compliance

Comply with this AD within the compliance times specified, unless already done.

Required actions

Except as specified in paragraph (h) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, European Union Aviation Safety Agency (EASA) AD 2020-0169R1, dated August 19, 2020 (EASA AD 2020-0169R1).

Unsafe condition

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. The FAA is issuing this AD to address this condition, which could lead to hot bleed air leakage in the pylon area, and possibly result in loss of the pneumatic system and exposure of the wing structure to high temperatures, and lead to reduced structural integrity of the airplane.

Affected ADs

None.
