1. The authority citation for part 39 continues to read as follows: Authority: 49 U.S.C. 106(g), 40113, 44701. 2. The FAA amends § 39.13 by adding the following new airworthiness directive: 2026-11-08 Airbus SAS: Amendment 39-23369; Docket No. FAA-2026-2280; Project Identifier MCAI-2025-01562-T. (a) Effective Date This airworthiness directive (AD) is effective July 9, 2026. (b) Affected ADs None. (c) Applicability This AD applies to Airbus SAS Model A350-941 airplanes, certificated in any category, as identified in European Union Aviation Safety Agency (EASA) AD 2025-0210, dated September 24, 2025 (EASA AD 2025-0210). (d) Subject Air Transport Association (ATA) of America Code 57, Wings. (e) Unsafe Condition This AD was prompted by a determination that double overcoating sealant was not applied during production on certain fasteners in the center wing box and belly faring junction for both left-hand and right-hand sides, and certain fasteners are susceptible to rotation. The FAA is issuing this AD to address incorrect fastener installation. This unsafe condition, if not addressed, could result in loss of fastener clamping and crack of nut sealant cover, possibly resulting, in the case of a lightning strike, in a risk of a fuel tank explosion and consequent loss of the airplane. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Requirements 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 2025-0210. (h) Exceptions to EASA AD 2025-0210 (1) Where EASA AD 2025-0210 refers to its effective date, this AD requires using the effective date of this AD. (2) Where the definition of "Affected part" in EASA AD 2025-0210 specifies "as specified in the SB", this AD requires replacing that text with "as specified in Airbus Service Bulletin A350-57-P094, dated June 17, 2025". (3) This AD does not adopt the "Remarks" section of EASA AD 2025-0210. (i) Additional AD Provisions 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.
