The FAA is adopting a new airworthiness directive (AD) for all Airbus SAS Model A300 B4-601, B4-603, B4-620, B4-622, B4-605R, B4-622R, C4-605R Variant F, F4-605R, and F4-622R airplanes; Model A310 series airplanes; Model A318, A319, A320, and A321 series airplanes; Model A330-200, -200 Freighter, and -300 series airplanes; Model A330-841 and -941 airplanes; and Model A340-211, -212, -213, -311, -312, -313, -541, and -642 airplanes. This AD was prompted by chemical oxygen generators that failed to activate in service and during maintenance activities. This AD requires replacing affected oxygen generators and prohibits the installation of affected parts, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. 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 2024-0198, dated October 18, 2024 (EASA AD 2024-0198).
(1) Where EASA AD 2024-0198 refers to December 6, 2023 (the effective date of EASA AD 2023-0209, dated November 22, 2023), this AD requires using the effective date of this AD.
(2) Where EASA AD 2024-0198 refers to its effective date, this AD requires using the effective date of this AD.
(3) Where paragraph (1) of EASA AD 2024-0198 specifies to “replace each affected part with a serviceable part in accordance with the instructions of the AOT,” this AD requires replacing that text with “replace each affected part with an oxygen generator, eligible for installation, which is not an affected part, in accordance with paragraph 5.6 of the AOT.”
(4) Where the service information referenced in EASA AD 2024-0198 specifies a method of compliance for removal and installation of the oxygen container/generator in accordance with the service information or aircraft maintenance manual, for this AD, either method is acceptable.
(5) The service information referenced in EASA AD 2024-0198 specifies to report inspection results to Airbus and return affected oxygen generators to Collins Aerospace. For this AD, reporting inspection results is required at the applicable time specified in paragraph (h)(5)(i) or (ii) of this AD, but returning affected oxygen generators to Collins Aerospace is not required by this AD.
(i) If the affected oxygen generator was replaced on or after the effective date of this AD: Submit the report within 40 days after the replacement.
(ii) If the affected oxygen generator was replaced before the effective date of this AD: Submit the report within 40 days after the effective date of this AD.
(6) This AD does not adopt the “Remarks” section of EASA AD 2024-0198.
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, mail it to the address identified in paragraph (j) of this AD. Information may be emailed 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 (h)(3), (h)(4), and (i)(2) of this AD, if any service information referenced in EASA AD 2024-0198 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.
