Airworthiness Directive · Amendment 39-22498 · Hydraulic power
Airbus SAS Airplanes
This AD applies 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 reports of a non-full life clearance in the low-pressure hydraulic pipes of the nose landing gear return line, due to two quality escapes. This AD requires replacing the affected aluminum pipes with titanium pipes, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. This AD also prohibits the installation of affected parts. 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 2022-0217R1, dated March 1, 2023 (EASA AD 2022-0217R1).
(1) Where EASA AD 2022-0217R1 refers to its effective date, this AD requires using the effective date of this AD.
(2) This AD does not adopt the “Remarks” section of EASA AD 2022-0217R1.
(3) Where EASA AD 2022-0217R1 refers to November 18, 2022 (the effective date of EASA AD 2022-0217), this AD requires using the effective date of this AD.
(4) Where table (2) of EASA AD 2022-0217R specifies a compliance time of “Before exceeding 6 years since aeroplane date of manufacture, or within 10 months after the effective date of this revised AD, whichever occurs later”, this AD requires using “Before exceeding 6 years since airplane date of manufacture, within 10 months after the effective date of this AD, or prior to the accumulation of 7,000 total flight cycles, whichever occurs latest.”
The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager, International Validation 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 International Validation Branch, send it to the attention of the person identified in paragraph (j) of this AD. Information may be emailed to: 9-AVS-AIR-730-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, International Validation 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 service information 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.
