The FAA's summary their words, unchanged
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.

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 (AD) 2020-02-14, Amendment 39-19828 (85 FR 6757, February 6, 2020); and b. Adding the following new AD: 2025-18-06 Airbus SAS: Amendment 39-23133; Docket No. FAA-2025-0742; Project Identifier MCAI-2024-00682-T. (a) Effective Date This airworthiness directive (AD) is effective October 23, 2025. (b) Affected ADs This AD replaces AD 2020-02-14, Amendment 39-19828 (85 FR 6757, February 6, 2020) (AD 2020-02-14). (c) Applicability 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. (d) Subject Air Transport Association (ATA) of America Code 35, Oxygen. (e) Unsafe Condition This AD was prompted by a report that during inspection of the installation of oxygen containers, certain fasteners of the oxygen containers and adjacent panels in the passenger supply channels (PSCs) were found damaged or unlocked, which could result in insufficient clearance between the oxygen container and adjacent panels. This AD was also prompted by a determination that additional airplanes may be affected by the same unsafe condition. The FAA is issuing this AD to address damaged and unlocked fasteners of the oxygen containers and adjacent panels in the PSCs, which could result in insufficient clearance between the oxygen container and adjacent panels. The unsafe condition, if not addressed, could prevent the opening of the oxygen containers and result in failure of oxygen masks to deploy and provide supplemental oxygen supply in case of an in-flight decompression, possibly resulting in injury to cabin occupants. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Requirements 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). (h) Exceptions to 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. (i) No Reporting Requirement Although the material referenced in EASA AD 2024-0220 specifies to submit certain information to the manufacturer, this AD does not include that requirement.
