Airworthiness Directive · Amendment 39-23133 · Oxygen
Airbus SAS Airplanes
This AD applies to Airbus SAS Model A350-941 and -1041 airplanes, certificated in any category, having manufacturer serial numbers (MSNs) listed in Airbus Alert Operators Transmission (AOT) A35P015-19, Revision 01, dated June 19, 2019; and Airbus AOT A35P023-24, Revision 01, dated July 25, 2024.
The FAA is superseding Airworthiness Directive (AD) 2020-02- 14, which applied to certain Airbus SAS Model A350-941 and -1041 airplanes. AD 2020-02-14 required a one-time inspection of the oxygen containers and adjacent panels and applicable corrective actions. Since the FAA issued AD 2020-02-14, it was determined that additional airplanes may be affected by the same unsafe condition. This AD continues to require the actions in AD 2020-02-14 and expands the applicability to include additional airplanes. 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 2024-0220, dated November 20, 2024 (EASA AD 2024-0220).
(1) Where EASA AD 2024-0220 refers to “09 September 2019 [the effective date of EASA AD 2019-0210],” this AD requires using March 12, 2020 (the effective date of AD 2020-02-14).
(2) Where EASA AD 2024-0220 refers to its effective date, this AD requires using the effective date of this AD.
(3) Where the “Groups” definition in EASA AD 2024-0220 specifies “Group 1 aeroplanes are those having an MSN as listed in the AOT1”, this AD requires replacing that text with “Group 1 airplanes are those having an MSN as listed in Airbus AOT A35P015-19, Revision 01, dated June 19, 2019”.
(4) Where the “Groups” definition in EASA AD 2024-0220 specifies “Group 2 aeroplanes are those having an MSN as listed in the AOT2”, this AD requires replacing that text with “Group 2 airplanes are those having an MSN as listed in Airbus AOT A35P023-24, Revision 01, dated July 25, 2024”.
(5) This AD does not adopt the “Remarks” section of EASA AD 2024-0220.
Although the material referenced in EASA AD 2024-0220 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 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: 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.
