(c) Applicability This AD applies to all Airbus SAS airplanes specified in paragraphs (c)(1) through (7) of this AD, certificated in any category. (1) Model A330-201, -202, -203, -223, and -243 airplanes. (2) Model A330-223F and -243F airplanes. (3) Model A330-301, -302, -303, -321, -322, -323, -341, -342, and -343 airplanes.

(d) Subject Air Transport Association (ATA) of America Code 49, Airborne Auxiliary Power. (e) Unsafe Condition This AD was prompted by a report of cracks in the fuel control unit housing assembly of a Honeywell GTCP331-350 auxiliary power unit (APU), which caused fuel leakage in the APU compartment. The FAA is issuing this AD to address the cracked fuel control unit housing assemblies. The unsafe condition, if not addressed, could result in an uncommanded APU in-flight shutdown, or fire in the APU compartment, which could result in damage to 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 2023-0057, dated March 16, 2023 (EASA AD 2023-0057). (h) Exceptions to EASA AD 2023-0057 (1) Where EASA AD 2023-0057 refers to its effective date; this AD requires using the effective date of this AD. (2) This AD does not adopt the "Remarks" section of EASA AD 2023-0057. (3) Where EASA AD 2023-0057 defines "the SB," for this AD, operators must use Honeywell Service Bulletin GTCP331-49-7954, dated December 19, 2007. (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]. 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, 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 (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.
