Airworthiness Directive · Amendment 39-23078 · Flight controls
Airbus SAS Airplanes
Superseded. A later AD replaced this one: AD 2025-25-12. 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 of loss of control of an outboard aileron surface due to hydraulic fluid contaminating an electronic card of the flight control remote module (FCRM). This AD requires replacing any affected elevator FCRM and prohibits installing aileron or spoiler FCRMs in place of elevator or rudder FCRMs. This AD also limits the installation of FCRMs under certain conditions. The FAA is issuing this AD to address the unsafe condition on these products.
Except as specified in paragraphs (h) and (i) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, European Union Aviation Safety Agency (EASA) AD 2025-0129, dated June 5, 2025 (EASA AD 2025-0129).
(1) Where EASA AD 2025-0129 refers to “07 May 2025 [the effective date of EASA AD 2025-0099]”, this AD requires using the effective date of this AD.
(2) Where EASA AD 2025-0129 refers to its effective date, this AD requires using the effective date of this AD.
(3) Where paragraph (1) of EASA AD 2025-0129 states “do not swap”, for this AD replace that text with “do not replace”.
(4) Where paragraph (2) of EASA AD 2025-0129 states “is reported on an aeroplane”, for this AD replace that text with “is documented in the aircraft maintenance records or has been reported to Airbus”.
(5) Where Table 1 of EASA AD 2025-0129 states “close to”, for this AD replace that text with “adjacent to”.
(6) This AD does not adopt the “Remarks” section of EASA AD 2025-0129.
Although the material referenced in EASA AD 2025-0129 specifies to submit certain information to the manufacturer, this AD does not include that requirement.
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 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)(1) 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 (j)(2) of this AD, if any material referenced in EASA AD 2025-0129 that contains paragraphs that are labeled as RC, the instructions in RC paragraphs, including subparagraphs under an RC paragraph, must be done to comply with this AD; any paragraphs, including subparagraphs under those paragraphs, that are not identified as RC are recommended. The instructions in paragraphs, including subparagraphs under those paragraphs, 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 instructions identified as RC can be done and the airplane can be put back in an airworthy condition. Any substitutions or changes to instructions identified as RC require approval of an AMOC.
