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 adding the following new airworthiness directive: 2026-10-19 Airbus SAS: Amendment 39-23359; Docket No. FAA-2026-4641; Project Identifier MCAI-2026-00340-T. (a) Effective Date This airworthiness directive (AD) is effective June 8, 2026. (b) Affected ADs None. (c) Applicability This AD applies to all Airbus SAS airplanes identified in paragraphs (c)(1) through (4) 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. (4) Model A330-841 airplanes and A330-941 airplanes. (d) Subject Air Transport Association (ATA) of America Code 28, Fuel. (e) Unsafe Condition This AD was prompted by a report of an in-service event and relevant investigation, which found that, under specific conditions, a dormant failure of a standby fuel pump could lead to a certain amount of fuel being trapped in the aft section of the inner tank and being unusable. The FAA is issuing this AD to address dormant failure of a standby fuel pump, which could lead to inability to use fuel trapped in either of the aft inner tanks, possibly resulting in overestimating the useable fuel available on board, and subsequent uncommanded in-flight engine shutdown. (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 2026-0073, dated April 1, 2026; corrected April 7, 2026 (EASA AD 2026-0073). (h) Exceptions to EASA AD 2026-0073 (1) Where EASA AD 2026-0073 refers to its effective date, this AD requires using the effective date of this AD. (2) Where EASA AD 2026-0073 defines an affected part as "any part number eligible for installation in accordance with Airbus instructions", this AD requires replacing that text with "any part number eligible for installation". (3) Where Note 1 of EASA AD 2026-0073 specifies "The action(s) required by paragraph (1) of this AD may be accomplished by suitably authorised flight crew under the provisions of Commission Regulation (EU) No 1321/2014 145.A.30(j)3 or M.A.606(h)1, as applicable;", this AD requires replacing that text with "Operational checks specified in paragraph (1) of EASA AD 2026-0073 may be accomplished by personnel authorized in accordance with the operator's approved maintenance or inspection program. In accordance with 14 CFR 121.363 and 121.369, certificate holders are responsible for establishing procedures for the accomplishment, coordination, recording, and corrective action associated with required maintenance and inspections. Operators should evaluate the appropriateness of flightcrew accomplishment of these actions within the context of their specific operation, including applicable training programs, standard operating procedures, maintenance coordination processes, flightcrew workload considerations, and safety risk management practices." (4) Where paragraph (2) of EASA AD 2026-0073 defines a discrepancy as "any discrepancy, as identified in the AOT", this AD requires replacing that text with "any result that does not match the applicable result identified in the "Result" column in the table of paragraph A., "Operational check of the Standby Fuel Pump," in paragraph 5.5 of the AOT". (5) Where paragraph (3) of EASA AD 2026-0073 states "it is determined that an affected part is defective", this AD requires replacing that text with "it is determined the affected part cannot meet all results identified in the "Result" column in the table of paragraph A., "Operational check of the Standby Fuel Pump," in paragraph 5.5 of the AOT". (6) This AD does not adopt the "Remarks" section of EASA AD 2026-0073. (i) Additional AD Provisions 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 . 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 paragraph (i)(2) of this AD, if any material referenced in EASA AD 2026-0073 that 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.
