SUPPLEMENTARY INFORMATION:
Background
The FAA issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 by adding an AD that would
apply to all Airbus SAS Model:
• A318–111, –112, –121, and –122
airplanes;
• A319–111, –112, –113, –114, –115,
–131, –132, –133, –151N, –153N, and
–171N airplanes;
• A320–211, –212, –214, –216, –231,
–232, –233, –251N, –252N, –253N,
–271N, –272N, and –273N airplanes;
• A321–111, –112, –131, –211, –212,
–213, –231, –232, –251N, –251NX,
–252N, –252NX, –253N, –253NX,
–271N, –271NX, –272N, and –272NX
airplanes;
• A330–201, –202, –203, –223, –223F,
–243, –243F, –301, –302, –303, –321,
–322, –323, –341, –342, –343, –841, and
–941 airplanes; and
• A340–211, –212, –213, –311, –312,
–313, –541, and –642 airplanes.
The NPRM published in the Federal
Register on October 13, 2023 (88 FR
70913). The NPRM was prompted by
AD 2023–0094, dated May 8, 2023,
issued by EASA, which is the Technical
Agent for the Member States of the
European Union (EASA AD 2023–0094)
(also referred to as the MCAI). The
MCAI states that a production
deficiency of some SLGOC batches was
identified during production testing of
newly manufactured oxygen containers.
Subsequent investigation identified
missing heat treatment of the actuation
pin of the SLGOC, which could cause its
jamming, with consequent failure of
PO 00000
Frm 00010
Fmt 4700
Sfmt 4700
oxygen flow activation. This condition,
if not corrected, could prevent
supplemental oxygen supply in case of
decompression in the cabin/lavatory,
possibly resulting in injury to lavatory
occupants.
In the NPRM, the FAA proposed to
require replacing affected SLGOCs and
prohibiting the installation of affected
SLGOCs, as specified in EASA AD
2023–0094. The FAA is issuing 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–2023–1994.
Discussion of Final Airworthiness
Directive
Comments
The FAA received a comment from
Air Line Pilots Association,
International (ALPA) who supported the
NPRM without change.
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 comment 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, this AD is
adopted as proposed in the NPRM.
None of the changes will increase the
economic burden on any operator.
Related Service Information Under 1
CFR Part 51
EASA AD 2023–0094 specifies
procedures for replacing affected
SLGOCs and prohibiting the installation
of affected SLGOCs. 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.
Costs of Compliance
The FAA estimates that this AD
affects 728 airplanes of U.S. registry.
The FAA estimates the following costs
to comply with this AD:
E:\FR\FM\03JAR1.SGM

243
Federal Register / Vol. 89, No. 2 / Wednesday, January 3, 2024 / Rules and Regulations
ESTIMATED COSTS FOR REQUIRED ACTIONS
Labor cost

product
Cost on U.S.
operators
2 work-hours × $85 per hour = $170 ..........................................................................................
$4,570
$4,740
$3,450,720
The FAA has included all known
costs in its cost estimate. According to
the manufacturer, however, some or all
of the costs of this AD may be covered
under warranty, thereby reducing the
cost impact on affected operators.
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.

SUPPLEMENTARY INFORMATION:
Background
The FAA issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 to supersede AD 2023–04–10,
Amendment 39–22357 (88 FR 20743,
April 7, 2023) (AD 2023–04–10). AD
2023–04–10 applied to all Dassault
Aviation Model MYSTERE–FALCON
900 airplanes. AD 2023–04–10 required
revising the existing maintenance or
inspection program, as applicable, to
incorporate new or more restrictive
airworthiness limitations. The FAA
issued AD 2023–04–10 to address
reduced structural integrity of the
airplane. AD 2023–04–10 specifies that
accomplishing the revision required by
that AD terminates the requirements of
paragraph (g)(1) of AD 2010–26–05,
Amendment 39–16544 (75 FR 79952,
December 21, 2010) (AD 2010–26–05)
for Dassault Aviation Model MYSTERE–
FALCON 900 airplanes only. This AD
therefore continues to allow that
terminating action.
The NPRM published in the Federal
Register on July 21, 2023 (88 FR 47086);
corrected August 14, 2023 (88 FR
54933). The NPRM was prompted by
AD 2023–0046, dated March 2, 2023,
issued by EASA, which is the Technical
Agent for the Member States of the
European Union (EASA AD 2023–0046)
(also referred to as the MCAI). The
MCAI states that new or more restrictive
airworthiness limitations have been
developed.
In the NPRM, the FAA proposed to
continue to require the actions in AD
2023–04–10 and to require revising the
existing maintenance or inspection
program, as specified in EASA AD
2023–0046. The FAA is issuing this AD
to address reduced structural integrity
of the airplane.

SUPPLEMENTARY INFORMATION:
Background
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 by adding an AD that would apply to all Airbus SAS Model:
A318-111, -112, -121, and -122 airplanes;
A319-111, -112, -113, -114, -115, -131, -132, -133, -151N,
-153N, and -171N airplanes;
A320-211, -212, -214, -216, -231, -232, -233, -251N, -
252N, -253N, -271N, -272N, and -273N airplanes;
A321-111, -112, -131, -211, -212, -213, -231, -232, -251N,
-251NX, -252N, -252NX, -253N, -253NX, -271N, -271NX, -272N, and -272NX
airplanes;
A330-201, -202, -203, -223, -223F, -243, -243F, -301, -
302, -303, -321, -322, -323, -341, -342, -343, -841, and -941
airplanes; and
A340-211, -212, -213, -311, -312, -313, -541, and -642
airplanes.
The NPRM published in the Federal Register on October 13, 2023 (88
FR 70913). The NPRM was prompted by AD 2023-0094, dated May 8, 2023,
issued by EASA, which is the Technical Agent for the Member States of
the European Union (EASA AD 2023-0094) (also referred to as the MCAI).
The MCAI states that a production deficiency of some SLGOC batches was
identified during production testing of newly manufactured oxygen
containers. Subsequent investigation identified missing heat treatment
of the actuation pin of the SLGOC, which could cause its jamming, with
consequent failure of oxygen flow activation. This condition, if not
corrected, could prevent supplemental oxygen supply in case of
decompression in the cabin/lavatory, possibly resulting in injury to
lavatory occupants.
In the NPRM, the FAA proposed to require replacing affected SLGOCs
and prohibiting the installation of affected SLGOCs, as specified in
EASA AD 2023-0094. The FAA is issuing 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-2023-1994.
Discussion of Final Airworthiness Directive
Comments
The FAA received a comment from Air Line Pilots Association,
International (ALPA) who supported the NPRM without change.
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
comment 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,
this AD is adopted as proposed in the NPRM. None of the changes will
increase the economic burden on any operator.
Related Service Information Under 1 CFR Part 51
EASA AD 2023-0094 specifies procedures for replacing affected
SLGOCs and prohibiting the installation of affected SLGOCs. 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.
Costs of Compliance
The FAA estimates that this AD affects 728 airplanes of U.S.
registry. The FAA estimates the following costs to comply with this AD:
[[Page 243]]
Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
2 work-hours x $85 per hour = $170........................... $4,570 $4,740 $3,450,720
----------------------------------------------------------------------------------------------------------------
The FAA has included all known costs in its cost estimate.
According to the manufacturer, however, some or all of the costs of
this AD may be covered under warranty, thereby reducing the cost impact
on affected operators.
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.
