Airworthiness Directives; Airbus SAS Airplanes; Correction
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule; request for comment; correction.
-----------------------------------------------------------------------
SUMMARY: The FAA is correcting an airworthiness directive (AD) that was
published in the Federal Register. That AD applies to all Airbus SAS
Model A319-151N, -153N, -171N, and -173N airplanes; Model A320-251N, -
252N, -253N, -271N, -272N, and -273N airplanes; and Model A321-251N, -
252N, -253N, -271N, -272N, -251NX, -252NX, -253NX, -271NX, -272NX, -
253NY, and -271NY airplanes. As published, a reference to a European
Union Aviation Safety Agency (EASA) AD specified in the regulatory text
is incorrect. This document corrects that error. In all other respects,
the original document remains the same.
DATES: This correction is effective August 29, 2025. The effective date
of AD 2025-16-12 remains August 29, 2025. The date for submitting
comments on AD 2025-16-12 remains September 29, 2025.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of August 29,
2025 (90 FR 39102, August 14, 2025).

SUPPLEMENTARY INFORMATION:
Comments Invited
The FAA invites you to send any written relevant data, views, or
arguments about AD 2025-16-12. Submit comments as instructed in AD
2025-16-12, Amendment 39-23110 (90 FR 39102, August 14, 2025) (AD 2025-
16-12).
Background
AD 2025-16-12, requires revising the existing airplane flight
manual (AFM) and the existing FAA-approved minimum equipment list
(MEL), allows replacement of each affected high-pressure bleed valve
(HPV) as an optional terminating action, and prohibits the installation
of affected parts. That AD applies to all Airbus SAS Model A319-151N, -
153N, -171N, and -173N airplanes; Model A320-251N, -252N, -253N, -271N,
-272N, and -273N airplanes; and Model A321-251N, -252N, -253N, -271N, -
272N, -251NX, -252NX, -253NX, -271NX, -272NX, -253NY, and -271NY
airplanes.
Need for the Correction
As published, a reference to an EASA AD specified in the regulatory
text of AD 2025-16-12 is incorrect. Paragraph (h)(3) of AD 2025-16-12
requires replacing text from EASA AD 2025-0096, dated April 28, 2025
(EASA AD 2025-0096) with ``revise the operator's existing FAA-approved
MEL by incorporating the applicable information identified in ``The
MMEL update'' as defined in EASA AD 2024-0157,'' whereas it should
state ``as defined in EASA AD 2025-0096.''
Material Incorporated by Reference Under 1 CFR Part 51
The FAA reviewed EASA AD 2025-0096, which specifies procedures for
amending the existing AFM by incorporating a temporary revision,
implementing a master MEL (MMEL) update, and repetitively replacing
each affected HPV clip. EASA AD 2025-0096 includes an optional
terminating action of replacing each affected HPV with a non-affected
HPV and prohibits installing an affected HPV on any airplane. This
material is reasonably available because the interested parties have
access to it through their normal course of business or by the means
identified in the ADDRESSES section.

Correction of Publication
This document corrects an error and correctly adds the AD as an
amendment to 14 CFR 39.13. Although no other part of the preamble or
regulatory information has been corrected, the FAA is publishing the
entire rule in the Federal Register.
The effective date of this AD remains August 29, 2025.
Since this action only corrects a typographical error, it has no
adverse economic impact and imposes no additional burden on any person.
Therefore, the FAA has determined that notice and public procedures are
unnecessary.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Incorporation by
reference, Safety.
Adoption of the Amendment
Accordingly, pursuant to the authority delegated to me by the
Administrator, the FAA amends part 39 of the Federal Aviation
Regulations (14 CFR part 39) as follows:
PART 39--AIRWORTHINESS DIRECTIVES
0
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Corrected]
0
2. The FAA amends Sec. 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:
[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, 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.
