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: 2025-16-12 Airbus SAS: Amendment 39-23110; Docket No. FAA-2025-1733; Project Identifier MCAI-2025-00762-T. (a) Effective Date This airworthiness directive (AD) is effective August 29, 2025. (b) Affected ADs None. (c) Applicability This AD applies to all Airbus SAS airplanes identified in paragraphs (c)(1) through (3) of this AD, certificated in any category. (1) Model A319-151N, -153N, -171N, and -173N airplanes. (2) Model A320-251N, -252N, -253N, -271N, -272N, and -273N airplanes. (3) Model A321-251N, -252N, -253N, -271N, -272N, -251NX, -252NX, -253NX, -271NX, -272NX, -253NY, and -271NY airplanes. (d) Subject Air Transport Association (ATA) of America Code 36, Pneumatic. (e) Unsafe Condition This AD was prompted by occurrences of high-pressure bleed valve (HPV) butterfly seal retention clip rupture. The FAA is issuing this AD to address high pressure and temperatures in the duct downstream from the pressure regulating valve, which could lead to duct burst and result in damage to several systems or the airframe 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 2025-0096, dated April 28, 2025 (EASA AD 2025-0096). (h) Exceptions to EASA AD 2025-0096 (1) Where EASA AD 2025-0096 refers to its effective date, this AD requires using the effective date of this AD. (2) Where paragraphs (1) and (3) of EASA AD 2025-0096 specify to "inform all flight crews, and, thereafter, operate the aeroplane accordingly," this AD does not require those actions as those actions are already required by existing FAA operating regulations (see 14 CFR 91.9, 91.505, 121.137, 121.628(a)(2) and 121.628(a)(5)). (3) Where paragraph (3) of EASA AD 2025-0096 specifies to "implement the instructions of the MMEL update, as applicable, depending on aeroplane configuration (see Note 1 of this AD), on the basis of which the operator's MEL must be amended", this AD requires replacing that text with "revise the operator's existing FAA-approved MEL by incorporating the applicable information identified in "The MMEL update" as defined in EASA AD 2025-0096". (4) Where the service information required by EASA AD 2025-0096 specifies discarding parts, this AD requires removing those parts from service. (5) This AD does not adopt the requirements specified in paragraph (4) of EASA AD 2025-0096. (6) This AD does not adopt the "Remarks" section of EASA AD 2025-0096. (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 2025-0096 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.
