Abstract
The FAA is superseding Airworthiness Directive (AD) 2023-11- 08, which applied to all Airbus SAS Model A330-841 and -941 airplanes. AD 2023-11-08 required maintenance actions, including a high-pressure valve (HPV) seal integrity test, repetitive replacement of the HPV clips, revision of the existing airplane flight manual (AFM), and implementation of updates to the FAA-approved operator's minimum equipment list (MEL). This AD was prompted by the determination that the replacement intervals required by AD 2023-11-08 must be reduced to address the unsafe condition. This AD continues to require the actions in AD 2023-11-08. This AD also reduces the HPV clip replacement intervals, requires an additional revision of the existing AFM for certain airplanes, and limits the installation of HPV clips, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.

ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2023-11-
08, which applied to all Airbus SAS Model A330-841 and -941 airplanes.
AD 2023-11-08 required maintenance actions, including a high-pressure
valve (HPV) seal integrity test, repetitive replacement of the HPV
clips, revision of the existing airplane flight manual (AFM), and
implementation of updates to the FAA-approved operator's minimum
equipment list (MEL). This AD was prompted by the determination that
the replacement intervals required by AD 2023-11-08 must be reduced to
address the unsafe condition. This AD continues to require the actions
in AD 2023-11-08. This AD also reduces the HPV clip replacement
intervals, requires an additional revision of the existing AFM for
certain airplanes, and limits the installation of HPV clips, as
specified in a European Union Aviation Safety Agency (EASA) AD, which
is incorporated by reference. The FAA is issuing this AD to address the
unsafe condition on these products.
DATES: This AD is effective April 4, 2025.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of April 4,
2025.

SUPPLEMENTARY INFORMATION:
Background
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 to supersede AD 2023-11-08, Amendment 39-22454 (88 FR
38384, June 13, 2023) (AD 2023-11-08). AD 2023-11-08 applied to all
Airbus SAS Model A330-841 and -941 airplanes. AD 2023-11-08 required
maintenance actions, including an HPV seal integrity test, repetitive
replacement of the HPV clips, revision of the existing AFM, and
implementation of updates to the FAA-approved operator's MEL. The FAA
issued AD 2023-11-08 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.
The NPRM published in the Federal Register on March 28, 2024 (89 FR
21450). The NPRM was prompted by AD 2023-0111, dated May 26, 2023 (EASA
AD 2023-0111), issued by EASA, which is the Technical Agent for the
Member States of the European Union. EASA AD 2023-0111 stated that it
has been determined that the interval for the HPV clip replacement must
be based also on flight cycles accumulated by the HPV clip (i.e., the
interval must be reduced), and that additional instructions, applicable
depending on the bleed monitoring computer (BMC) software (SW)
configuration, have been identified (i.e., an additional revision of
the existing AFM is necessary for certain airplanes).
In the NPRM, the FAA proposed to continue to require the actions in
AD 2023-11-08, as specified in EASA AD 2023-0111. The NPRM also
proposed to reduce the HPV clip replacement intervals, require an
additional revision of the existing AFM for certain airplanes, and
limit the installation of HPV clips, as specified in EASA AD 2023-0111.
Since the FAA issued the NPRM, EASA superseded AD 2023-0111 and
issued EASA AD 2023-0111R1, dated May 28, 2024 (EASA AD 2023-0111R1)
(also referred to as the MCAI), to provide relief from certain
requirements for certain Airbus SAS Model A330-841 and -941 airplanes.
The MCAI states, after issuance of EASA AD 2023-0111, Airbus released a
modification that introduces the BMC SW 5.0 standard, a service
bulletin that provides retrofit instructions, and an alert operators
transmission that specifies the effectivity of its instructions
depending on the installed BMC SW. The MCAI also states that the BMC SW
5.0 standard supports improved monitoring features, which allow a
relaxation of the maintenance requirements, operational procedures, and
limitations required by EASA AD 2023-0111.
The FAA reviewed the MCAI and determined it provides relief for
airplanes that are equipped with BMC SW 5.0 or a later FAA-approved SW
standard. The FAA also determined the requirements of the MCAI have not
changed for airplanes that are not equipped with BMC SW 5.0 or a later
FAA-approved SW standard. In
[[Page 10854]]
addition, the MCAI adds an optional terminating action for the HPV seal
integrity test for Group 1 airplanes (airplanes that are equipped with
BMC SW 4.0) and specifies that after following the terminating action
(modification of the airplane), the airplane is considered a Group 2
airplane. Therefore, the FAA has revised this AD to adopt the
requirements of the MCAI except for any differences identified as
exceptions in the regulatory text of this AD.
The FAA is issuing this AD to address these products. You may
examine the MCAI in the AD docket at <a href="http://regulations.gov">regulations.gov</a> under Docket No.
FAA-2024-0766.
Discussion of Final Airworthiness Directive
Comments
The FAA received a comment from the Air Line Pilots Association,
International (ALPA) who supported the NPRM without change.
The FAA received an additional comment from one individual. The
following presents the comment received on the NPRM and the FAA's
response to that comment.
Request To Explain What Prompted the Proposed AD
An individual requested the FAA explain what inspired the agency to
create the proposed AD. The commenter did not request any change to the
proposed AD.
The FAA is issuing this AD to supersede AD 2023-11-08, which was
prompted by reports of leaking bleed system HPVs, likely due to HPV
clip failure and sealing ring damage. A leaking HPV may expose the PRV
to high pressure, possibly damaging the PRV itself and preventing its
closure. This 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. In the preamble to AD 2023-11-08, the FAA
stated the AD was considered an interim action and anticipated further
action. After issuing AD 2023-11-08, EASA superseded AD 2022-0227,
dated November 24, 2022 (which corresponds to AD 2023-11-08) and issued
EASA AD 2023-0111, dated May 26, 2023, to require additional actions.
Following review of EASA AD 2023-0111, dated May 26, 2023, the FAA
determined that additional actions are required to address the unsafe
condition. This AD does so by reducing the replacement interval for the
HPV clip and requiring additional applicable instructions depending on
the BMC software configuration. This AD is also considered an interim
action, and further AD action may follow. As previously stated, this AD
also incorporates the changes specified in EASA AD 2023-0111R1. The FAA
has not changed this AD as a result of this comment.
Additional Change Made to This AD
The FAA has added paragraph (h)(4) to this AD to explain that where
EASA AD 2023-0111R1 refers to ``02 June 2023 [the effective date of the
original issue of this AD],'' this AD requires using the effective date
of this AD. The FAA has also redesignated subsequent paragraphs
accordingly.
The exception in paragraph (h)(5) of the proposed AD (referred to
as paragraph (h)(6) in this AD) stated that informing all flightcrews
of AFM revisions and dispatch limitations is not required by the AD
because those actions are already required by FAA regulations. The
exception referenced the relevant regulations for AFMs (14 CFR 91.9,
91.505, and 121.137). The FAA has revised paragraph (h)(6) of this AD
to also reference the relevant regulations for MELs (14 CFR
121.628(a)(2) and (5)) that address dispatch limitations.
Conclusion
This product has been approved by the aviation authority of another
country and is approved for operation in the United States. Pursuant to
the FAA's bilateral agreement with this State of Design Authority, it
has notified the FAA of the unsafe condition described in the MCAI
referenced above. The FAA reviewed the relevant data, considered the
comments received, and determined that air safety requires adopting
this AD as proposed. Accordingly, the FAA is issuing this AD to address
the unsafe condition on this product. Except for minor editorial
changes, and any other changes described previously, this AD is adopted
as proposed in the NPRM. None of the changes will increase the economic
burden on any operator.

estimates for the maintenance actions specified in this AD.
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
This AD will not have federalism implications under Executive Order
13132. This AD will 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 that this AD:
(1) Is not a ``significant regulatory action'' under Executive
Order 12866,
(2) Will not affect intrastate aviation in Alaska, and
(3) Will not have a significant economic impact, positive or
negative, on a substantial number of small entities under the criteria
of the Regulatory Flexibility Act.

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.
