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 2022-19-05, Amendment 39-22174 (87 FR 54870, dated September 8, 2022); and b. Adding the following new AD: 2023-11-08 Airbus SAS: Amendment 39-22454; Docket No. FAA-2023-0156; Project Identifier MCAI-2022-01511-T. (a) Effective Date This airworthiness directive (AD) is effective July 18, 2023. (b) Affected ADs This AD replaces AD 2022-19-05, Amendment 39-22174 (87 FR 54870, September 8, 2022) (AD 2022-19-05). (c) Applicability This AD applies to all Airbus SAS Model A330-841 and -941 airplanes, certificated in any category. (d) Subject Air Transport Association (ATA) of America Code: 36, Pneumatic; 75, Air. (e) Unsafe Condition This AD was prompted by reports of leaking bleed system high pressure valves (HPVs), likely due to HPV clip failure and sealing ring damage, and by the development of additional instructions and maintenance procedures to address HPV failures. The FAA is issuing this AD to address a leaking HPV, which may expose the pressure regulating valve (PRV), which is installed downstream from the HPV, to high pressure, possibly damaging the PRV itself and preventing its closure. The unsafe condition, if not addressed, could result in high pressure and temperatures in the duct downstream from the PRV, with possible duct burst, damage to several systems, and consequent loss of control of the airplane. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Requirements 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 2022-0227, dated November 24, 2022 (EASA AD 2022-0227). (h) Exceptions to EASA AD 2022-0227 (1) Where EASA AD 2022-0227 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). (2) Where EASA AD 2022-0227 refers to its effective date, this AD requires using the effective date of this AD. (3) Where paragraphs (1) and (4) of EASA AD 2022-0227 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 (see 14 CFR 91.9, 91.505, and 121.137). (4) This AD does not adopt the reporting requirements of paragraph (17) of EASA AD 2022-0227. (5) This AD does not adopt the "Remarks" section of EASA AD 2022-0227. (i) Additional AD Provisions The following provisions also apply to this AD: (1) Alternative Methods of Compliance (AMOCs): The Manager, International Validation 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 International Validation Branch, send it to the attention of the person identified in paragraph (j) of this AD. Information may be emailed to: [email protected]. (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 2022-19-05 are approved as AMOCs for the corresponding provisions of EASA AD 2022-0227 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, International Validation 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(s) (i)(2) of this AD, if any service information contains procedures or tests that are identified as RC, those procedures and tests must be done to comply with this AD; any procedures or tests that are not identified as RC are recommended. Those procedures and tests that are 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 procedures and tests identified as RC can be done and the airplane can be put back in an airworthy condition. Any substitutions or changes to procedures or tests identified as RC require approval of an AMOC.
