Federal Aviation
Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking
(NPRM).
AGENCY:
The FAA proposes to
supersede Airworthiness Directive (AD)
2023–11–08, which applies to all Airbus
SAS Model A330–841 and –941
airplanes. AD 2023–11–08 requires
maintenance actions, including a highpressure 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). Since
the FAA issued AD 2023–11–08, the
agency determined that the replacement
intervals required by AD 2023–11–08
must be reduced in order to address the
unsafe condition. This proposed AD
would continue to require the actions in
AD 2023–11–08 and would reduce the
HPV clip replacement intervals, and
would require, for certain airplanes, an
additional revision of the existing AFM.
This proposed AD would also limit the
installation of HPV clips, as specified in
a European Union Aviation Safety
Agency (EASA AD), which is proposed
for incorporation by reference (IBR). 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 May 13, 2024.
ADDRESSES: You may send comments,
using the procedures found in 14 CFR
11.43 and 11.45, by any of the following

Background
The FAA issued AD 2023–11–08,
Amendment 39–22454 (88 FR 38384,
June 13, 2023) (AD 2023–11–08), for all
Airbus SAS Model A330–841 and –941
airplanes. AD 2023–11–08 was
prompted by an MCAI originated by
EASA, which is the Technical Agent for
the Member States of the European
Union. EASA issued AD 2022–0227,
dated November 24, 2022 (EASA AD
2022–0227), to correct an unsafe
condition. EASA AD 2022–0227
superseded EASA AD 2022–0181, dated
August 29, 2022 (which prompted FAA
AD 2022–19–05, Amendment 39–22174
(87 FR 54870, September 8, 2022)).
AD 2023–11–08 requires 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 FAAapproved operator’s MEL. The FAA
issued AD 2023–11–08 to address a
leaking HPV, which 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 2023–11–08 Was
Issued
Since the FAA issued AD 2023–11–
08, EASA superseded AD 2022–0227
and issued EASA AD 2023–0111, dated
May 26, 2023 (EASA AD 2023–0111)
(referred to after this as the MCAI), to
correct an unsafe condition for all
Airbus SAS Model A330–841 and –941
airplanes. The MCAI states 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 additional instructions
applicable depending on BMC software
configuration, have been identified (i.e.,
an additional revision of the existing
AFM is necessary for certain airplanes).
The FAA is proposing this AD to
address the unsafe condition on these
products. You may examine the MCAI
in the AD docket at regulations.gov
under Docket No. FAA–2024–0766.
Explanation of Retained Requirements
Although this proposed AD does not
explicitly restate the requirements of AD
2023–11–08, this proposed AD would
retain certain requirements of AD 2023–
11–08. Those requirements are
referenced in EASA AD 2023–0111,
which, in turn, is referenced in
paragraph (g) of this proposed AD.
Related Service Information Under 1
CFR Part 51
EASA AD 2023–0111 specifies
procedures for the following actions:
• Revision of the Limitations section
of the existing AFM and removal of the
previously required limitations.
• Implementation of the instructions
of the MMEL update on the basis of
which the operator’s MEL must be
amended with new provisions and
procedures for the following items: Air
Conditioning Pack, Engine Bleed Air
Supply System, Engine Bleed IP
(Intermediate Pressure) Check Valve,
and Engine Bleed HP Valve and cancel
the dispatch restrictions. Amending the
applicable AFM of an airplane by
incorporating the AFM Temporary
Revision (TR) TR813 does not allow
removal of the MMEL update as
required by paragraph (7) of this [EASA]
AD for that airplane.
• A seal integrity test of each HPV,
and corrective actions (including
replacement of the HPV, and a detailed
inspection of the wing bellow on engine
1(2) and replacement of any damaged or
deformed wing bellow). Also,
accomplishing a Seal Integrity Test of
each HPV in accordance with the
instructions of the AOT.
EASA AD 2023–0111 also describes
the following maintenance instructions

for group 1 and group 2, among other
actions, to be accomplished following
certain faults or failures:
• HPV troubleshooting procedure and
additional maintenance actions after
any Class 1 maintenance message
associated to an HPV fault, and
corrective actions (including
replacement of the HPV or wing
bellow).
• HPV seal integrity test and the
additional maintenance actions after
any Class 1 or Class 2 maintenance
message associated to a PRV fault, and
corrective actions (including
replacement of the HPV and PRV, and
a detailed inspection of the wing bellow
on engine 1(2) and replacement of any
damaged or deformed wing bellow).
• A visual (borescope) inspection of
the engine bleed air system (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 high pressure/intermediate
pressure (HP/IP) duct, the y-duct, and
the pylon ducts after any failure of an
HPV clip and/or any of the HPV
butterfly sealing rings, and corrective
actions (including removing FOD and
replacing the IPCV or PRV).
• A seal integrity test of each HPV
after any take-off or go-around
accomplished with ‘‘packs OFF’’ or
‘‘APU bleed ON’’ or ‘‘engine bleed
OFF,’’ and corrective actions (including
replacement of the HPV, and a detailed
inspection of the wing bellow on engine
1(2) and replacement of any damaged or
deformed wing bellow).
• Additional actions to be performed
for any Class 1 maintenance message
associated with an HPV fault.
• Initial and repetitive replacement of
each HPV clip with a new HPV clip.
• Reporting to Airbus of any failure
detected during the accomplishment of
any maintenance action, seal integrity
test, or visual inspection specified in
EASA AD 2022–0181.
EASA AD 2023–0111 also specifies
that HPV clips may be installed
provided they are new and serviceable,
and replaced in accordance with
paragraph (17) Table 1.

FAA’s Determination
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

Federal Register / Vol. 89, No. 61 / Thursday, March 28, 2024 / Proposed Rules
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 AFM including all updates. 14
CFR 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 of the
information contained in the operator’s
MEL. Furthermore, 14 CFR 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.
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
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 2023–11–08.
This proposed AD would require
accomplishing the actions specified in
EASA AD 2023–0111 described
previously, except for any differences
identified as exceptions in the
regulatory text of this proposed AD and
except as discussed under ‘‘Differences
Between this Proposed AD and the
MCAI.’’
Compliance With AFM and MEL
Revisions
EASA AD 2023–0111 requires
operators to ‘‘inform all flight crews’’ of
revisions to the existing AFM and MEL,
and thereafter to ‘‘operate the airplane
accordingly.’’ However, this AD does
not specifically require those actions, as
those actions are already required by
FAA regulations.
FAA regulations require operators to
furnish to pilots any changes to the
AFM (for example, 14 CFR 121.137),
and to ensure the pilots are familiar
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 2023–0111 by
reference in the FAA final rule. This
proposed AD would, therefore, require
compliance with EASA AD 2023–0111
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 2023–0111 does not mean
that operators need 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 2023–0111.
Service information required by EASA
AD 2023–0111 for compliance will be
available at regulations.gov under
Docket No. FAA–2024–0766 after the
FAA final rule is published.
Interim Action
The FAA considers that this proposed
AD would be an interim action. The
FAA anticipates that further AD action
will follow.
Costs of Compliance
The FAA estimates that this AD, if
adopted as proposed, would affect 27
airplanes of U.S. registry. The FAA
estimates the following costs to comply
with this proposed AD:

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.

(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
(HPVs), likely due to HPV clip failure and
sealing ring damage, and by the
determination that the replacement intervals
required by AD 2023–11–08 must be reduced
to address the unsafe condition. The FAA is
issuing this AD to address a leaking HPV,
which 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 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 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 2023–0111, dated
May 26, 2023 (EASA AD 2023–0111).
(h) Exceptions to EASA AD 2023–0111
(1) Where EASA AD 2023–0111 refers to
‘‘05 September 2022 (the effective date of
EASA AD 2022–0181),’’ this AD requires
using September 15, 2022 (the effective date
of AD 2022–19–05, Amendment 39–22174,
(87 FR 54870, September 8, 2022)).
(2) Where paragraph (19) of EASA AD
2023–0111 refers to ‘‘08 December 2022 (the
effective date of EASA AD 2022–0227),’’ this
AD requires using the effective date of this
AD.
(3) Where paragraph (21) of EASA AD
2023–0111 refers to ‘‘08 December 2022 (the
effective date of EASA AD 2022–0227),’’ this
AD requires using July 18, 2023 (the effective
date of AD 2023–11–08).
(4) Where EASA AD 2023–0111 refers to its
effective date, this AD requires using the
effective date of this AD.
(5) Where paragraphs (1), (2), (3), and (7)
of EASA AD 2023–0111 specify to inform all
flight crews of airplane flight manual (AFM)
revisions and dispatch limitations, and
thereafter to operate the airplane accordingly,
this AD does not require those actions, as
those actions are already required by existing
FAA regulations (see 14 CFR 91.9, 91.505,
and 121.137).
(6) This AD does not adopt the reporting
requirements of paragraph (23) of EASA AD
2023–0111.

RIN 2120-AA64
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)
2023-11-08, which applies to all Airbus SAS Model A330-841 and -941
airplanes. AD 2023-11-08 requires 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). Since the FAA issued AD 2023-11-08, the
agency determined that the replacement intervals required by AD 2023-
11-08 must be reduced in order to address the unsafe condition. This
proposed AD would continue to require the actions in AD 2023-11-08 and
would reduce the HPV clip replacement intervals, and would require, for
certain airplanes, an additional revision of the existing AFM. This
proposed AD would also limit the installation of HPV clips, as
specified in a European Union Aviation Safety Agency (EASA AD), which
is proposed for incorporation by reference (IBR). 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 May 13,
2024.
ADDRESSES: You may send comments, using the procedures found in 14 CFR
11.43 and 11.45, by any of the following methods:

for this rulemaking.
Background
The FAA issued AD 2023-11-08, Amendment 39-22454 (88 FR 38384, June
13, 2023) (AD 2023-11-08), for all Airbus SAS Model A330-841 and -941
airplanes. AD 2023-11-08 was prompted by an MCAI originated by EASA,
which is the Technical Agent for the Member States of the European
Union. EASA issued AD 2022-0227, dated November 24, 2022 (EASA AD 2022-
0227), to correct an unsafe condition. EASA AD 2022-0227 superseded
EASA AD 2022-0181, dated August 29, 2022 (which prompted FAA AD 2022-
19-05, Amendment 39-22174 (87 FR 54870, September 8, 2022)).
AD 2023-11-08 requires 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,
which 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 2023-11-08 Was Issued
Since the FAA issued AD 2023-11-08, EASA superseded AD 2022-0227
and issued EASA AD 2023-0111, dated May 26, 2023 (EASA AD 2023-0111)
(referred to after this as the MCAI), to correct an unsafe condition
for all Airbus SAS Model A330-841 and -941 airplanes. The MCAI states
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 additional instructions
applicable depending on BMC software configuration, have been
identified (i.e., an additional revision of the existing AFM is
necessary for certain airplanes).
The FAA is proposing this AD to address the unsafe condition on
these products. You may examine the MCAI in the AD docket at
regulations.gov under Docket No. FAA-2024-0766.
Explanation of Retained Requirements
Although this proposed AD does not explicitly restate the
requirements of AD 2023-11-08, this proposed AD would retain certain
requirements of AD 2023-11-08. Those requirements are referenced in
EASA AD 2023-0111, which, in turn, is referenced in paragraph (g) of
this proposed AD.
Related Service Information Under 1 CFR Part 51
EASA AD 2023-0111 specifies procedures for the following actions:
Revision of the Limitations section of the existing AFM
and removal of the previously required limitations.
Implementation of the instructions of the MMEL update on
the basis of which the operator's MEL must be amended with new
provisions and procedures for the following items: Air Conditioning
Pack, Engine Bleed Air Supply System, Engine Bleed IP (Intermediate
Pressure) Check Valve, and Engine Bleed HP Valve and cancel the
dispatch restrictions. Amending the applicable AFM of an airplane by
incorporating the AFM Temporary Revision (TR) TR813 does not allow
removal of the MMEL update as required by paragraph (7) of this [EASA]
AD for that airplane.
A seal integrity test of each HPV, and corrective actions
(including replacement of the HPV, and a detailed inspection of the
wing bellow on engine 1(2) and replacement of any damaged or deformed
wing bellow). Also, accomplishing a Seal Integrity Test of each HPV in
accordance with the instructions of the AOT.
EASA AD 2023-0111 also describes the following maintenance
instructions for group 1 and group 2, among other actions, to be
accomplished following certain faults or failures:
HPV troubleshooting procedure and additional maintenance
actions after any Class 1 maintenance message associated to an HPV
fault, and corrective actions (including replacement of the HPV or wing
bellow).
HPV seal integrity test and the additional maintenance
actions after any Class 1 or Class 2 maintenance message associated to
a PRV fault, and corrective actions (including replacement of the HPV
and PRV, and a detailed inspection of the wing bellow on engine 1(2)
and replacement of any damaged or deformed wing bellow).
A visual (borescope) inspection of the engine bleed air
system (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 high pressure/intermediate
pressure (HP/IP) duct, the y-duct, and the pylon ducts after any
failure of an HPV clip and/or any of the HPV butterfly sealing rings,
and corrective actions (including removing FOD and replacing the IPCV
or PRV).
A seal integrity test of each HPV after any take-off or
go-around accomplished with ``packs OFF'' or ``APU bleed ON'' or
``engine bleed OFF,'' and corrective actions (including replacement of
the HPV, and a detailed inspection of the wing bellow on engine 1(2)
and replacement of any damaged or deformed wing bellow).
Additional actions to be performed for any Class 1
maintenance message associated with an HPV fault.
Initial and repetitive replacement of each HPV clip with a
new HPV clip.
Reporting to Airbus of any failure detected during the
accomplishment of any maintenance action, seal integrity test, or
visual inspection specified in EASA AD 2022-0181.
EASA AD 2023-0111 also specifies that HPV clips may be installed
provided they are new and serviceable, and replaced in accordance with
paragraph (17) Table 1.
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
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
[[Page 21452]]
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 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 2023-11-
08. This proposed AD would require accomplishing the actions specified
in EASA AD 2023-0111 described previously, except for any differences
identified as exceptions in the regulatory text of this proposed AD and
except as discussed under ``Differences Between this Proposed AD and
the MCAI.''
Compliance With AFM and MEL Revisions
EASA AD 2023-0111 requires operators to ``inform all flight crews''
of revisions to the existing AFM and MEL, and thereafter to ``operate
the airplane accordingly.'' However, this AD does not specifically
require those actions, as those actions are already required by FAA
regulations.
FAA regulations require operators to 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 AFM including all updates. 14
CFR 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 of the information contained in the
operator's MEL. Furthermore, 14 CFR 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 2023-0111 by reference in the FAA
final rule. This proposed AD would, therefore, require compliance with
EASA AD 2023-0111 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 2023-0111 does not mean that
operators need 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 2023-
0111. Service information required by EASA AD 2023-0111 for compliance
will be available at regulations.gov under Docket No. FAA-2024-0766
after the FAA final rule is published.
Interim Action
The FAA considers that this proposed AD would be an interim action.
The FAA anticipates that further AD action will follow.
Costs of Compliance
The FAA estimates that this AD, if adopted as proposed, would
affect 27 airplanes of U.S. registry. The FAA estimates the following
costs to comply with this proposed AD:
Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
Cost on U.S.
Action Labor cost Parts cost Cost per product operators
----------------------------------------------------------------------------------------------------------------
Retained actions from AD 2023-11- 14 work-hours x Up to $28......... Up to $1,218...... Up to $32,886.
08. $85 per hour =
$1,190.
New proposed actions............ 1 work-hour x $85 $85............... $85............... $2,295.
per hour = $85.
----------------------------------------------------------------------------------------------------------------
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.
hour = Up to $1,615.
------------------------------------------------------------------------
The FAA has received no definitive data on which to base the cost
estimates for the maintenance actions specified in this proposed 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.
[[Page 21453]]
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

ring damage, and by the determination that the replacement intervals
required by AD 2023-11-08 must be reduced to address the unsafe
condition. The FAA is issuing this AD to address a leaking HPV,
which 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 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 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

(i) Additional AD Provisions
The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager,
International Validation 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
International Validation Branch, mail it to the address identified
in paragraph (j) of this AD. Information may be emailed to: [email protected].
(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 2023-11-08 are approved as
AMOCs for the corresponding provisions of EASA AD 2023-0111 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, International
Validation 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 service information referenced
in EASA AD 2023-0111 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.
