Airworthiness Directive · Amendment 39-21502 · Pneumatic
Airbus SAS Airplanes
Superseded. A later AD replaced this one: AD 2023-06-12. Comply with the one in force.
This AD applies to all Airbus SAS Model A350-941 and -1041 airplanes, certificated in any category.
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.
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).
(1) Where EASA AD 2020-0169R1 refers to its effective date, this AD requires using the effective date of this AD.
(2) The “Remarks” section of EASA AD 2020-0169R1 does not apply to this AD.
(3) Where the service information referenced in paragraph (2) of EASA AD 2020-0169R1 specifies doing a “general visual inspection” and “detailed inspection” of bleed gimbal records and bleed gimbals, this AD allows for an inspection to determine the part number and manufacturing date of the bleed gimbals. A review of airplane maintenance records is acceptable in lieu of this inspection for the part number of the bleed gimbals if it can be conclusively determined from that review.
Although the service information referenced in EASA AD 2020-0169R1 specifies to submit certain information to the manufacturer, this AD does not include that requirement.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
