Airworthiness Directive · Amendment 39-22174 · Airbus SAS Airplanes
Airbus SAS Airplanes
Superseded. A later AD replaced this one: AD 2023-11-08. 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 Emergency Airworthiness Directive (AD) 2022-18-51, which applied to all Airbus SAS Model A330-841 and -941 airplanes. Emergency AD 2022-18-51 required revising the existing airplane flight manual (AFM) to incorporate additional limitations prohibiting takeoff for certain airplane configurations; specified airplane dispatch restrictions using certain provisions of the A330 master minimum equipment list (MMEL) or amending the existing FAA- approved operator's minimum equipment list (MEL); and required obtaining and accomplishing instructions following certain maintenance messages. Since the FAA issued Emergency AD 2022-18-51, additional instructions and maintenance procedures have been developed to address failures of the high pressure valve (HPV). This AD continues to require the actions specified in Emergency AD 2022-18-51, and also requires maintenance actions, including an HPV seal integrity test, repetitive replacement of the HPV clips, revision of the existing AFM, and implementation of updates to the FAA-approved operator's MEL, 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 2022-0181, dated August 29, 2022 (EASA AD 2022-0181).
(1) Where EASA AD 2022-0181 refers to “18 August 2022 [the effective date of EASA AD 2022-0170-E],” this AD requires using “August 19, 2022.”
(2) Where EASA AD 2022-0181 refers to its effective date, this AD requires using the effective date of this AD.
(3) Where paragraphs (1), (2), (4), and (7) of EASA AD 2022-0181 specify to inform all flightcrews of airplane flight manual (AFM) revisions and dispatch limitations, and thereafter to operate the airplane accordingly, this AD does not require those actions, as those actions are already required by existing FAA regulations.
(4) Where paragraph (2) of EASA AD 2022-0181 prohibits the dispatch of an airplane under specified provisions of the A330 master minimum equipment list (MMEL) items, this AD alternatively allows revising the operator's existing FAA-approved minimum equipment list (MEL) by removing the items specified in paragraph (2) of EASA AD 2022-0181, if accomplished before further flight as of August 19, 2022, as specified in FAA Emergency AD 2022-18-51.
(5) The “Remarks” section of EASA AD 2022-0181 does not apply to this AD.
