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: a. Removing Airworthiness Directive 2025-13-12, Amendment 39-23078 (90 FR 30577, July 10, 2025); and b. Adding the following new airworthiness directive: 2025-25-12 Airbus SAS: Amendment 39-23220; Docket No. FAA-2025-5390; Project Identifier MCAI-2025-01470-T. (a) Effective Date This airworthiness directive (AD) is effective January 13, 2026. (b) Affected ADs This AD replaces AD 2025-13-12, Amendment 39-23078 (90 FR 30577, July 10, 2025) (AD 2025-13-12). (c) Applicability This AD applies to all Airbus SAS Model A350-941 and -1041 airplanes, certificated in any category. (d) Subject Air Transport Association (ATA) of America Code 27, Flight Controls. (e) Reason This AD was prompted by a report of loss of control of an outboard aileron surface due to hydraulic fluid contaminating an electronic card of the flight control remote module (FCRM). The FAA is issuing this AD to address FCRM electronic cards exposed to hydraulic fluid contamination. This condition, if not detected and corrected, could lead to runaway of rudder or elevator surface, resulting in loss of control 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, European Union Aviation Safety Agency (EASA) AD 2025-0197R1, dated September 26, 2025 (EASA AD 2025-0197R1). (h) Exceptions to EASA AD 2025-0197R1 (1) Where EASA AD 2025-0197R1 refers to "07 May 2025 [the effective date of EASA AD 2025-0099]," this AD requires using July 25, 2025 (the effective date of AD 2025-13-12). (2) Where EASA AD 2025-0197R1 refers to "12 June 2025 [the effective date of EASA AD 2025-0129]," this AD requires using July 25, 2025 (the effective date of AD 2025-13-12).

(4) Where paragraph (1) of EASA AD 2025-0197R1 states "do not swap", this AD requires replacing that text with "do not replace". (5) Where paragraph (2) of EASA AD 2025-0197R1 states "is reported on an aeroplane", this AD requires replacing that text with "is documented in the aircraft maintenance records or has been reported to Airbus". (6) Where table 1 of EASA AD 2025-0197R1 states "close to", this AD requires replacing that text with "adjacent to". (7) Where paragraph (13) of EASA AD 2025-0197R1 specifies installing certain software standards on the airplane in accordance with Airbus approved instructions, for this AD, those instructions must be approved using a method specified in paragraph (j)(2) of this AD. (8) This AD does not adopt the "Remarks" section of EASA AD 2025-0197R1. (i) No Reporting Requirement Although material referenced in EASA AD 2025-0197R1 specifies to submit certain information to the manufacturer, this AD does not include that requirement. (j) 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 (k) of this AD and email to: [email protected] . (i) Before using any approved AMOC, notify your appropriate principal inspector, or lacking a principal inspector, the manager of the responsible Flight Standards Office. (ii) AMOCs approved previously for AD 2025-13-12 are approved as AMOCs for the corresponding provisions of EASA AD 2025-0197R1 that are required by paragraph (g) of this AD. (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 (j)(2) of this AD, where the service bulletins referenced in EASA AD 2025-0197R1 contain procedures or tests that are identified as RC, those procedures and tests must be done to comply with this AD; and where the alert operators transmission (AOT) referenced in EASA AD 2025-0197R1 contains paragraphs that are labeled as RC, the instructions in RC paragraphs, including subparagraphs under and RC paragraph, must be done to comply with this AD.

Procedures and tests, and instructions in paragraphs including subparagraphs under those paragraphs, as applicable, 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, tests, and instructions, as applicable, identified as RC can be done and the airplane can be put back in an airworthy condition. Any substitutions or changes to procedures, tests, or instructions, as applicable, identified as RC require approval of an AMOC.
