Airworthiness Directive · Amendment 39-22963 · Pneumatic
Airbus SAS Airplanes
Superseded. A later AD replaced this one: AD 2026-20-15. Comply with the one in force.
This AD applies to all Airbus SAS Model A330-841 and -941 airplanes, certificated in any category.
The FAA is superseding Airworthiness Directive (AD) 2023-11- 08, which applied to all Airbus SAS Model A330-841 and -941 airplanes. AD 2023-11-08 required maintenance actions, including a high-pressure valve (HPV) seal integrity test, repetitive replacement of the HPV clips, revision of the existing airplane flight manual (AFM), and implementation of updates to the FAA-approved operator's minimum equipment list (MEL). This AD was prompted by the determination that the replacement intervals required by AD 2023-11-08 must be reduced to address the unsafe condition. This AD continues to require the actions in AD 2023-11-08. This AD also reduces the HPV clip replacement intervals, requires an additional revision of the existing AFM for certain airplanes, and limits the installation of HPV clips, 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 2023-0111R1, dated May 28, 2024 (EASA AD 2023-0111R1).
(1) Where EASA AD 2023-0111R1 refers to “05 September 2022 [the effective date of EASA AD 2022-0181],” this AD requires using September 15, 2022 (the effective date of AD 2022-19-05, Amendment 39-22174 (87 FR 54870, September 8, 2022)).
(2) Where paragraph (19) of EASA AD 2023-0111R1 refers to “08 December 2022 (the effective date of EASA AD 2022-0227),” this AD requires using the effective date of this AD.
(3) Where paragraph (21) of EASA AD 2023-0111R1 refers to “08 December 2022 (the effective date of EASA AD 2022-0227),” this AD requires using July 18, 2023 (the effective date of AD 2023-11-08).
(4) Where EASA AD 2023-0111R1 refers to “02 June 2023 [the effective date of the original issue of this AD],” this AD requires using the effective date of this AD.
(5) Where EASA AD 2023-0111R1 refers to its effective date, this AD requires using the effective date of this AD.
(6) Where paragraphs (1), (2), (3), and (7) of EASA AD 2023-0111R1 specify to inform all flightcrews of airplane flight manual (AFM) revisions and dispatch limitations, and thereafter operate the airplane accordingly, this AD does not require those actions, as those actions are already required by existing FAA regulations (see 14 CFR 91.9, 91.505, and 121.137 for AFM requirements and 14 CFR 121.628(a)(2) and (5) for minimum equipment list requirements).
(7) This AD does not adopt the reporting requirements of paragraph (23) of EASA AD 2023-0111R1.
(8) This AD does not adopt the “Remarks” section of EASA AD 2023-0111R1.
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 (j) of this AD and email to: AMOC@faa.gov.
(i) Before using any approved AMOC, notify your appropriate principal inspector, or lacking a principal inspector, the manager of the responsible Flight Standards Office.
(ii) AMOCs approved previously for AD 2023-11-08 are approved as AMOCs for the corresponding provisions of EASA AD 2023-0111R1 that are required by paragraph (g) of this AD.
(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 paragraph (i)(2) of this AD, if any material referenced in EASA AD 2023-0111R1 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.
