Abstract
The FAA proposes to supersede Airworthiness Directive (AD) 2025-04-05, which applies to all Airbus SAS Model A330-841 and -941 airplanes. AD 2025-04-05 requires a revision of the existing airplane flight manual (AFM) and removal of the previously required limitations; a revision of the existing minimum equipment list (MEL); one-time or repetitive seal integrity tests of each engine bleed air system (EBAS) high pressure valve (HPV); additional maintenance instructions and corrective actions; and repetitive replacement of affected HPV clips; as applicable. AD 2025-04-05 also limits the installation of affected HPV clips. Since the FAA issued AD 2025-04-05, an improved EBAS HPV with unaffected HPV clips was certified, and it was determined that the bleed monitoring computer (BMC) software (SW) must be updated. This proposed AD would continue to require the actions in AD 2025-04-05, except for repetitive replacement of affected HPV clips. This proposed AD would also require updating the BMC SW, additional work, and an additional revision of the existing MEL for the engine bleed overpressure valve; as applicable. This proposed AD would also prohibit the installation of certain BMC SW. The FAA is proposing this AD to address the unsafe condition on these products.

Airworthiness Directives; Airbus SAS Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: The FAA proposes to supersede Airworthiness Directive (AD)
2025-04-05, which applies to all Airbus SAS Model A330-841 and -941
airplanes. AD 2025-04-05 requires a revision of the existing airplane
flight manual (AFM) and removal of the previously required limitations;
a revision of the existing minimum equipment list (MEL); one-time or
repetitive seal integrity tests of each engine bleed air system (EBAS)
high pressure valve (HPV); additional maintenance instructions and
corrective actions; and repetitive replacement of affected HPV clips;
as applicable. AD 2025-04-05 also limits the installation of affected
HPV clips. Since the FAA issued AD 2025-04-05, an improved EBAS HPV
with unaffected HPV clips was certified, and it was determined that the
bleed monitoring computer (BMC) software (SW) must be updated. This
proposed AD would continue to require the actions in AD 2025-04-05,
except for repetitive replacement of affected HPV clips. This proposed
AD would also require updating the BMC SW, additional work, and an
additional revision of the existing MEL for the engine bleed
overpressure valve; as applicable. This proposed AD would also prohibit
the installation of certain BMC SW. The FAA is proposing this AD to
address the unsafe condition on these products.
DATES: The FAA must receive comments on this proposed AD by July 20,
2026.

Background
The FAA issued AD 2025-04-05, Amendment 39-22963 (90 FR 10853,
February 28, 2025) (AD 2025-04-05), for all Airbus SAS Model A330-841
and -941 airplanes. AD 2025-04-05 was prompted by an MCAI originated by
EASA, which is the Technical Agent for the Member States of the
European Union. EASA issued EASA AD 2023-0111R1, dated May 28, 2024
(EASA AD
[[Page 33675]]
2023-0111R1), to correct an unsafe condition.
AD 2025-04-05 requires a revision of the existing AFM and removal
of the previously required limitations; a revision of the existing MEL;
one-time or repetitive seal integrity tests of each EBAS HPV;
additional maintenance instructions and corrective actions; and
repetitive replacement of affected HPV clips; as applicable. AD2025-04-
05 also limits the installation of affected HPV clips. The FAA issued
AD 2025-04-05 to address a leaking HPV that 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.
Actions Since AD 2025-04-05 Was Issued
AD 2025-04-05 explains that the FAA considers the requirements
``interim action'' and was considering further rulemaking. The FAA has
now determined that further rulemaking is necessary, and this proposed
AD follows from that determination.
Since the FAA issued AD 2025-04-05, EASA superseded EASA AD 2023-
0111R1 with EASA AD 2025-0104, dated May 7, 2025, which was revised by
EASA AD 2025-0104R1, dated March 19, 2026 (EASA AD 2025-0104R1) (also
referred to as the MCAI). The MCAI states, since EASA AD 2023-0111R1
was issued, an improved HPV has been certified (Airbus Modification
210503), which introduces several design improvements and is equipped
with HPV clips that do not have to be replaced at predefined intervals;
new service information has been issued, which provides instructions to
replace the affected HPV with the improved HPV; other service
information has been issued, which provides instructions to do
additional work on airplanes that have embodied Airbus Service Bulletin
A330-36-3055 at the original issue; new master minimum equipment list
(MMEL) content has been certified, which introduces additional
instructions for airplanes on which BMC SW 4.0 or 4.1 is installed. The
MCAI also states that it has been determined that the optional
modification to install BMC SW 5.0 must be mandated on airplanes on
which BMC SW 4.0 or 4.1 is installed, additional work defined in a
later revision of the other service information must be accomplished,
and new MMEL content must be implemented for airplanes on which BMC SW
4.0 or 4.1 is installed.
The FAA is proposing this AD to address the unsafe condition on
these products. You may examine the MCAI in the AD docket at
<a href="http://regulations.gov">regulations.gov</a> under Docket No. FAA-2026-4649.
Explanation of Retained Requirements
Although this proposed AD does not explicitly restate the
requirements of AD 2025-04-05, this proposed AD would retain certain
requirements of AD 2025-04-05. Those requirements are referenced in
EASA AD 2025-0104R1, which, in turn, is referenced in paragraph (g) of
this proposed AD.
Material Incorporated by Reference Under 1 CFR Part 51
EASA AD 2025-0104R1 specifies procedures for the following retained
actions:
<bullet> For Group 1 airplanes (equipped with BMC SW 4.0) and Group
2 airplanes (equipped with BMC SW 4.1 standard), a revision of the
Limitations section of the existing AFM; and for Groups 1 and 2 and
Group 3 (equipped with BMC SW 5.0 or later approved SW standard and an
affected HPV) airplanes, removal of the previously required
limitations.
<bullet> For Groups 1 and 2 airplanes, implementation of the MMEL
update that includes new provisions and procedures for Air Conditioning
Pack, Engine Bleed Air Supply System, Engine Bleed IP (Intermediate
Pressure) Check Valve, and Engine Bleed HP (High Pressure) Valve; and
cancellation of the dispatch restrictions.
<bullet> For Group 2 airplanes, a seal integrity test of each HPV;
for Group 1 airplanes, repetitive seal integrity tests of each HPV; and
corrective actions, which include replacement of the HPV, a detailed
inspection of the wing bellow on engine 1(2), and replacement of any
damaged or deformed wing bellow.
EASA AD 2025-0104R1 describes the following retained maintenance
instructions, among other actions, to be accomplished following certain
faults or failures, on Groups 1 and 2 airplanes:
<bullet> HPV troubleshooting procedure and additional maintenance
actions after any Class 1 maintenance message associated with an HPV
fault and corrective actions, which includes replacement of the HPV or
wing bellow.
<bullet> HPV seal integrity test and the additional maintenance
actions after any Class 1 or Class 2 maintenance message associated
with a PRV fault and corrective actions, which includes replacement of
the HPV and PRV, a detailed inspection of the wing bellow on engine
1(2), and replacement of any damaged or deformed wing bellow.
<bullet> A visual (borescope) inspection of the EBAS to detect
signs of foreign object debris (FOD), including metallic debris in the
butterfly valve and dents or damage of the flaps of the intermediate
pressure check valve (IPCV), and dents and missing segments in the PRV,
the header of the HP/IP duct, y-duct, and pylon ducts after any failure
of an HPV clip and/or any of the HPV butterfly sealing rings, and
corrective actions, which includes FOD removal and replacement of the
IPCV or PRV.
<bullet> A seal integrity test of each HPV after any takeoff or go-
around accomplished with ``packs OFF'' or ``APU bleed ON'' or ``engine
bleed OFF'' and corrective actions, which include replacement of the
HPV, a detailed inspection of the wing bellow on engine 1(2), and
replacement of any damaged or deformed wing bellow.
<bullet> Additional actions to be performed for any Class 1
maintenance message associated with an HPV fault.
EASA AD 2025-0104R1 also specifies the following retained
limitations for the installation of affected parts:
<bullet> For Groups 1, 2, and 3 airplanes, installation of an
affected HPV clip on an affected HPV on an airplane, provided it is a
new affected clip (i.e., not previously installed on any HPV) and that
following installation, it is replaced according to the referenced
service information.
<bullet> For Groups 1, 2, and 3 airplanes, installation of an
affected HPV on an airplane, provided it is a serviceable HPV and that
following installation, the affected HPV clips of that HPV are replaced
with new clips according to the referenced service information.
EASA AD 2025-0104R1 also specifies that, for Group 1 airplanes,
modification (update to BMC SW 4.1) of the airplane terminates the
repetitive seal integrity tests of each HPV.
EASA AD 2025-0104R1 specifies the following new actions:
<bullet> For Groups 1 and 2 airplanes, modification (update to BMC
SW 5.0) of the airplane, which includes deletion of the operations
engineering bulletin (OEB) reminder data from the flight warning
computer (FWC) database.
<bullet> For Group 3 airplanes, accomplishment of additional work
(deletion of the OEB reminder data from the FWC database).
<bullet> For Groups 1 and 2 airplanes, implementation of the MMEL
update that includes new provisions for Engine Bleed Overpressure
Valve.
[[Page 33676]]
EASA AD 2025-0104R1 also prohibits the installation of the
following affected parts:
<bullet> BMC SW 4.0 or BMC SW 4.1 on any Group 3 or Group 4
(embodied with Airbus modifications 210503 and 210504 in production)
airplane, and on any Group 1 or 2 airplane after modification (update
to BMC SW 5.0) of the airplane.
<bullet> An affected HPV on any Group 4 airplane.
EASA AD 2025-0104R1 also specifies that, for Groups 1, 2, and 3
airplanes, modification of both affected HPVs terminates the HPV clip
replacement for the airplane, provided no affected HPV is re-installed
on that airplane; and if modification of the two affected HPV are
accomplished at different times, the HPV clip replacement is only
applicable to the affected HPV.
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.
FAA's Determination
These products have been approved by the civil aviation authority
of another country and are approved for operation in the United States.
Pursuant to the FAA's bilateral agreement with this State of Design
Authority, that authority has notified the FAA of the unsafe condition
described in the MCAI referenced above. The FAA is issuing this NPRM
after determining that the unsafe condition described previously is
likely to exist or develop in other products of the same type design.
Proposed AD Requirements in This NPRM
This proposed AD would retain certain requirements of AD 2025-04-
05. This proposed AD would require accomplishing the actions specified
in EASA AD 2025-0104R1 described previously, except for any differences
identified as exceptions in the regulatory text of this proposed AD.
Compliance With AFM and MEL Revisions
EASA AD 2025-0104R1 requires operators to ``inform all flight
crews'' of revisions to the AFM and MEL, and thereafter to ``operate
the aeroplane accordingly.'' However, this proposed AD would not
specifically require those actions as those actions are already
required by FAA regulations. FAA regulations require operators furnish
to pilots any changes to the AFM (for example, 14 CFR 121.137) and to
ensure the pilots are familiar with the AFM (for example, 14 CFR
91.505). As with any other flightcrew training requirement, training on
the updated AFM content is tracked by the operators and recorded in
each pilot's training record, which is available for the FAA to review.
FAA regulations also require pilots to follow the procedures in the
existing AFM including all updates. Section 91.9 requires that any
person operating a civil aircraft must comply with the operating
limitations specified in the AFM. FAA regulations (14 CFR
121.628(a)(2)) require operators to provide pilots with access to all
the information contained in the operator's MEL. Further, Sec.
121.628(a)(5) requires airplanes to be operated under all applicable
conditions and limitations contained in the operator's MEL. Therefore,
including a requirement in this proposed AD to operate the airplane
according to the revised AFM and MEL would be redundant and
unnecessary.
Explanation of Required Compliance Information
In the FAA's ongoing efforts to improve the efficiency of the AD
process, the FAA developed a process to use some civil aviation
authority (CAA) ADs as the primary source of information for compliance
with requirements for corresponding FAA ADs. The FAA has been
coordinating this process with manufacturers and CAAs. As a result, the
FAA proposes to incorporate EASA AD 2025-0104R1 by reference in the FAA
final rule. This proposed AD would, therefore, require compliance with
EASA AD 2025-0104R1 in its entirety through that incorporation, except
for any differences identified as exceptions in the regulatory text of
this proposed AD. Using common terms that are the same as the heading
of a particular section in EASA AD 2025-0104R1 does not mean that
operators need to comply only with that section. For example, where the
AD requirement refers to ``all required actions and compliance times,''
compliance with this AD requirement is not limited to the section
titled ``Required Action(s) and Compliance Time(s)'' in EASA AD 2025-
0104R1. Material required by EASA AD 2025-0104R1 for compliance will be
available at <a href="http://regulations.gov">regulations.gov</a> under Docket No. FAA-2026-4649 after the
FAA final rule is published.
Costs of Compliance
The FAA estimates that this AD, if adopted as proposed, would
affect 22 airplanes of U.S. registry. The FAA estimates the following
costs to comply with this proposed AD:
Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------

airplanes (additional work). per hour = $170.
----------------------------------------------------------------------------------------------------------------
* The FAA has no definitive data to determine how many affected airplanes are in each airplane group.
The FAA estimates the following costs to do any necessary on-
condition actions that would be required based on the results of any
required actions. The FAA has no way of determining the number of
aircraft that might need these on-condition actions:
Estimated Costs of On-Condition Actions
------------------------------------------------------------------------
Labor cost Parts cost Cost per product
------------------------------------------------------------------------
Up to 19 work-hours x $85 per Up to $114,742.... Up to $116,357.

Authority for This Rulemaking
Title 49 of the United States Code specifies the FAA's authority to
issue rules on aviation safety. Subtitle I, section 106, describes the
authority of the FAA Administrator. Subtitle VII: Aviation Programs,
describes in more detail the scope of the Agency's authority.
The FAA is issuing this rulemaking under the authority described in
Subtitle VII, Part A, Subpart III, Section 44701: General requirements.
Under that section, Congress charges the FAA with promoting safe flight
of civil aircraft in air commerce by prescribing regulations for
practices, methods, and procedures the Administrator finds necessary
for safety in air commerce. This regulation is within the scope of that
authority because it addresses an unsafe condition that is likely to
exist or develop on products identified in this rulemaking action.
Regulatory Findings
The FAA determined that this proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD would not
have a substantial direct effect on the States, on the relationship
between the national government and the States, or on the distribution
of power and responsibilities among the various levels of government.
For the reasons discussed above, I certify this proposed
regulation:
(1) Is not a ``significant regulatory action'' under Executive
Order 12866,
(2) Would not affect intrastate aviation in Alaska, and
(3) Would not have a significant economic impact, positive or
negative, on a substantial number of small entities under the criteria
of the Regulatory Flexibility Act.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Incorporation by

The Proposed Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA proposes to amend 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 [Amended]
0
2. The FAA amends Sec. 39.13 by:
0
a. Removing Airworthiness Directive (AD) 2025-04-05, Amendment 39-22963
(90 FR 10853, February 28, 2025); and
0
b. Adding the following new AD:
Airbus SAS: Docket No. FAA-2026-4649; Project Identifier MCAI-2025-
00835-T.
(a) Comments Due Date
The FAA must receive comments on this airworthiness directive
(AD) by July 20, 2026.
(b) Affected ADs
This AD replaces AD 2025-04-05, Amendment 39-22963 (90 FR 10853,
February 28, 2025) (AD 2025-04-05).
(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.
(e) Unsafe Condition
This AD was prompted by reports of leaking bleed system high
pressure valves (HPV), likely due to HPV clip failure and sealing
ring damage. This AD was also prompted by certification of an
improved HPV with unaffected HPV clips and the determination that
the bleed monitoring computer (BMC) software must be updated. The
FAA is issuing this AD to address a leaking HPV that 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 paragraphs (h) and (i) of this AD: Comply
with all required actions and compliance times specified in, and in
accordance with, European Union Aviation Safety Agency (EASA) AD
2025-0104R1, dated March 19, 2026 (EASA AD 2025-0104R1).

effective date of EASA AD 2022-0181, dated August 29, 2022), this AD
requires using September 15, 2022 (the effective date of AD 2022-19-
05, Amendment 39-22174 (87 FR 54870, September 8, 2022)).
(7) Where EASA AD 2025-0104R1 defines a Serviceable HPV, in
part, as ``EBAS HPV, eligible for installation in accordance with
Airbus instructions'', this AD requires replacing that text with
``EBAS HPV eligible for installation''.
(8) Where paragraphs (1), (2), (3), (7), and (29) of EASA AD
2025-0104R1 specify to inform all flightcrews of airplane flight
manual (AFM) revisions and dispatch limitations, and thereafter
operate the airplane 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, and 121.137 for AFM
requirements and 14 CFR 121.628(a)(2) and (5) for minimum equipment
list requirements).
(9) Where paragraph (20) of EASA AD 2025-0104R1 specifies ``as
required by paragraph (17) of the original issue of this AD'', this
AD requires replacing that text with ``as required by AD 2025-04-05
as
[[Page 33678]]
specified in paragraph (17) of EASA AD 2023-0111R1''.
(10) Where paragraph (30) of EASA AD 2025-0104R1 specifies
``Modification of both EBAS HPV'', this AD requires replacing that
text with ``Modification of both affected HPVs''.
(11) This AD does not adopt the ``Remarks'' section of EASA AD
2025-0104R1.
(i) No Reporting Requirement
Although the material referenced in EASA AD 2025-0104R1
specifies to submit certain information to the manufacturer, this AD
does not include that requirement.
(j) 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 (k) of this AD and email to:
<a href="/cdn-cgi/l/email-protection#084945474b486e6969266f677e"><span class="__cf_email__" data-cfemail="1a5b5755595a7c7b7b347d756c">[email protected]</span></a>.
(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 2025-04-05 are approved as
AMOCs for the corresponding provisions of EASA AD 2025-0104R1 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, 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
paragraphs (i) and (j)(2) of this AD, if any material referenced in
EASA AD 2025-0104R1 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.
