Airworthiness Directive · Amendment 39-23285 · Wings
Airbus SAS Airplanes
This AD applies to Airbus SAS Model A350-941 airplanes, certificated in any category, as identified in European Union Aviation Safety Agency (EASA) AD 2026-0018, dated January 26, 2026 (EASA AD 2026-0018).
The FAA is adopting a new airworthiness directive (AD) for certain Airbus SAS Model A350-941 airplanes. This AD was prompted by a report of a non-conformity in the serialization process of certain fuse pins and retaining pins installed in the main landing gear (MLG) trunnion block attachment, resulting in a non-unique combination of part number and serial number that could lead to a lack of traceability. This AD requires doing a check to identify the part number and serial number of the affected parts. This AD also requires inspecting the affected MLG trunnion block attachment retaining pin and fuse pins, recording the combination of work order number and original serial number as the new serial number, and updating the maintenance records, as applicable. 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, EASA AD 2026-0018.
(1) Where EASA AD 2026-0018 refers to its effective date, this AD requires using the effective date of this AD.
(2) Where paragraph (4) of EASA AD 2026-0018 specifies “but not exceeding 72 months, 11700 flight cycles or 48750 flight hours”, this AD requires replacing that text with “but not exceeding 72 months, 11,700 flight cycles or 48,750 flight hours, whichever occurs first”.
(3) This AD does not adopt the “Remarks” section of EASA AD 2026-0018.
The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager, AIR-520, Continued Operational Safety Branch, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. In accordance with 14 CFR 39.19, send your request to your principal inspector or responsible Flight Standards Office, as appropriate. If sending information directly to the manager of the Continued Operational Safety Branch, send it to the attention of the person identified in paragraph (j) of this AD and email to: AMOC@faa.gov. Before using any approved AMOC, notify your appropriate principal inspector, or lacking a principal inspector, the manager of the responsible Flight Standards Office.
(2) Contacting the Manufacturer: For any requirement in this AD to obtain instructions from a manufacturer, the instructions must be accomplished using a method approved by the Manager, AIR-520, Continued Operational Safety Branch, FAA; or EASA; or Airbus SAS's EASA Design Organization Approval (DOA). If approved by the DOA, the approval must include the DOA-authorized signature.
(3) Required for Compliance (RC): Except as required by paragraph (i)(2) of this AD, if any material contains procedures or tests that are identified as RC, those procedures and tests must be done to comply with this AD; any procedures or tests that are not identified as RC are recommended. Those procedures and tests that are not identified as RC may be deviated from using accepted methods in accordance with the operator's maintenance or inspection program without obtaining approval of an AMOC, provided the procedures and tests identified as RC can be done and the airplane can be put back in an airworthy condition. Any substitutions or changes to procedures or tests identified as RC require approval of an AMOC.
