Airworthiness Directive · Amendment 39-22376 · Oxygen
Airbus SAS Airplanes
This AD applies to all Airbus SAS Model A350-941 and -1041 airplanes, certificated in any category.
The FAA is superseding Airworthiness Directive (AD) 2020-21- 07, which applied to all Airbus SAS Model A350-941 and -1041 airplanes. AD 2020-21-07 required replacement of affected passenger oxygen masks (which includes re-identifying the parts). This AD was prompted by a determination that additional parts are subject to the unsafe condition. This AD continues to require the actions in AD 2020-21-07, and also requires replacing additional affected parts; as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. This AD also prohibits 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 2022-0112, dated June 17, 2022 (EASA AD 2022-0112).
(1) Where EASA AD 2022-0112 refers to its effective date, this AD requires using the effective date of this AD.
(2) The “Remarks” section of EASA AD 2022-0112 does not apply to this AD.
(3) Where EASA AD 2022-0112 specifies to do the replacement and re-identification specified in Airbus Service Bulletin A350-35-P013, Revision 02, dated March 8, 2022, which specifies to inspect for the part number and serial number and then do a replacement; this AD only requires the replacement and re-identification.
(4) Where service information identified in EASA AD 2022-0112 specifies to do an inspection for the date of manufacture of the affected part, this AD does not require that inspection.
(5) Where Table 3 of EASA AD 2022-0112 specifies a compliance time for airplanes on which “the SB” has not been embodied, for this AD the compliance time for those airplanes is “before exceeding 72 months since airplane date of manufacture or within 30 days after the effective date of this AD, whichever occurs later.”
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 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.
