The FAA is superseding Airworthiness Directive (AD) 2023-25- 09, which applied to all Airbus SAS Model A318, A319, A320, A321, A330- 200, A330-200 Freighter, A330-300, A330-800, A330-900, A340-200, A340- 300, A340-500, and A340-600 series airplanes. AD 2023-25-09 required replacing SafeLav gaseous oxygen containers (SLGOCs) affected by a production deficiency and prohibiting the installation of affected SLGOCs. Since the FAA issued AD 2023-05-09, a new airplane model has been certified, on which affected parts could be installed in service. This AD continues to require the actions in AD 2023-25-09 and adds airplanes to the applicability. 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 2024-0197, dated October 18, 2024 (EASA AD 2024-0197).
(1) Where EASA AD 2024-0197 refers to “22 May 2023 [the effective date of EASA AD 2023-0094]”, this AD requires using “February 7, 2024 (the effective date of AD 2023-25-09)”.
(2) Where EASA AD 2024-0197 refers to its effective date, this AD requires using the effective date of this AD.
(3) This AD does not adopt the “Remarks” section of EASA AD 2024-0197.
Although the material referenced in EASA AD 2024-0197 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.
(3) Required for Compliance (RC): Except as required by paragraphs (i) and (j)(2) of this AD, if any material referenced in EASA AD 2024-0197 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.
