This AD was prompted by a determination that new or more restrictive airworthiness limitations are necessary. This AD requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations, 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 22, 2024. The Director of the Federal Register approved the incorporation by reference The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain Airbus SAS Model A318, A319, A320, and A321 airplanes. The NPRM published in the Federal Register on October 31, 2023 (88 FR 74376). The NPRM was prompted by AD 2023–0138, dated July 13, 2023 (EASA AD 2023–0138) (also referred to as the MCAI), issued by EASA, which is the Technical Agent for the Member States of the European Union. The MCAI states that new airworthiness limitations are necessary. In the NPRM, the FAA proposed to require revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations, as specified in EASA AD 2023–0138.

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 also received comments from Delta Air Lines. The following presents the comments received on the NPRM and the FAA’s response to each comment. Request for Clarification of Paragraph (i) Referencing Service Information Delta requested clarification of the statement in paragraph (i) of the proposed AD that references laterapproved revisions within the ‘‘Ref. Publications’’ section of EASA AD 2023–0138. Delta requested adding an exception in paragraph (h) of the proposed AD that replaces the language in the EASA AD 2023–0138 section ‘‘Ref. Publications’’ from ‘‘the abovementioned document, or of an ALS revision’’ to ‘‘the above-mentioned document, or of an ALS revision or variation.’’ Delta stated this change would help clarify whether an AMOC (alternative method of compliance) is required to use future variations of Airbus A318/A319/A320/A321 ALS Part 3 Certification Maintenance Requirements (CMR), Revision 08 (Var 8.3 or later). Delta also requested clarification of the statement within the section ‘‘Ref. Publications’’ of EASA AD 2023–0138, referred to in paragraph (i) of the proposed AD, that references laterapproved revisions ‘‘which include the technical content of the variation.’’ Delta wanted to know if a laterapproved variation or revision is acceptable to use if the technical content of the variation is updated in some way, and not exactly the same. The commenter requested this clarification to better understand the allowance provided by the provisions of the ‘‘Ref. Publications’’ section of EASA AD 2023–0138. The FAA disagrees with changing paragraph (h) of this AD. The later version of Airbus A318/A319/A320/ A321 ALS Part 3 Certification Maintenance Requirements (CMR) would be acceptable for compliance as E:\FR\FM\18MRR1.SGM 18MRR1 Federal Register / Vol. 89, No. 53 / Monday, March 18, 2024 / Rules and Regulations long as EASA has also approved it. Any subsequent issue of that document containing the technical information presented in that variation that has been approved by the certifying authority can be used without the need to obtain an AMOC. For confirmation regarding the appropriateness of using service information associated with this AD, Delta may contact their local FAA office for further guidance. 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, this AD is adopted as proposed in the NPRM. None of the changes will increase the economic burden on any operator. lotter on DSK11XQN23PROD with RULES1 Related Service Information Under 1 CFR Part 51 The FAA reviewed EASA AD 2023– 0138, which specifies new or more restrictive airworthiness limitations for airplane structures and safe life limits. This service information 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 1,680 airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD: The FAA has determined that revising the existing maintenance or inspection program takes an average of 90 workhours per operator, although the agency recognizes that this number may vary from operator to operator. Since operators incorporate maintenance or inspection program changes for their affected fleet(s), the FAA has determined that a per-operator estimate is more accurate than a per-airplane estimate. Therefore, the agency estimates the average total cost per operator to be $7,650 (90 work-hours ¥ $85 per work-hour). Authority for This Rulemaking Title 49 of the United States Code specifies the FAA’s authority to issue rules on aviation safety. Subtitle I, VerDate Sep<11>2014 16:01 Mar 15, 2024 Jkt 262001 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.

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 certain Airbus SAS 
Model A318, A319, A320, and A321 airplanes. The NPRM published in the 
Federal Register on October 31, 2023 (88 FR 74376). The NPRM was 
prompted by AD 2023-0138, dated July 13, 2023 (EASA AD 2023-0138) (also 
referred to as the MCAI), issued by EASA, which is the Technical Agent 
for the Member States of the European Union. The MCAI states that new 
airworthiness limitations are necessary.
    In the NPRM, the FAA proposed to require revising the existing 
maintenance or inspection program, as applicable, to incorporate new or 
more restrictive airworthiness limitations, as specified in EASA AD 
2023-0138.
    The FAA is issuing this AD to address safety-significant latent 
failures (that are not annunciated), which, in combination with one or 
more other specific failures or events, could result in a hazardous or 
catastrophic failure condition.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2023-2138.

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 also received comments from Delta Air Lines. The following 
presents the comments received on the NPRM and the FAA's response to 
each comment.

Request for Clarification of Paragraph (i) Referencing Service 
Information

    Delta requested clarification of the statement in paragraph (i) of 
the proposed AD that references later-approved revisions within the 
``Ref. Publications'' section of EASA AD 2023-0138. Delta requested 
adding an exception in paragraph (h) of the proposed AD that replaces 
the language in the EASA AD 2023-0138 section ``Ref. Publications'' 
from ``the above-mentioned document, or of an ALS revision'' to ``the 
above-mentioned document, or of an ALS revision or variation.'' Delta 
stated this change would help clarify whether an AMOC (alternative 
method of compliance) is required to use future variations of Airbus 
A318/A319/A320/A321 ALS Part 3 Certification Maintenance Requirements 
(CMR), Revision 08 (Var 8.3 or later).
    Delta also requested clarification of the statement within the 
section ``Ref. Publications'' of EASA AD 2023-0138, referred to in 
paragraph (i) of the proposed AD, that references later-approved 
revisions ``which include the technical content of the variation.'' 
Delta wanted to know if a later-approved variation or revision is 
acceptable to use if the technical content of the variation is updated 
in some way, and not exactly the same. The commenter requested this 
clarification to better understand the allowance provided by the 
provisions of the ``Ref. Publications'' section of EASA AD 2023-0138.
    The FAA disagrees with changing paragraph (h) of this AD. The later 
version of Airbus A318/A319/A320/A321 ALS Part 3 Certification 
Maintenance Requirements (CMR) would be acceptable for compliance as

[[Page 19235]]

long as EASA has also approved it. Any subsequent issue of that 
document containing the technical information presented in that 
variation that has been approved by the certifying authority can be 
used without the need to obtain an AMOC. For confirmation regarding the 
appropriateness of using service information associated with this AD, 
Delta may contact their local FAA office for further guidance.

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, 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

    The FAA reviewed EASA AD 2023-0138, which specifies new or more 
restrictive airworthiness limitations for airplane structures and safe 
life limits. This service information 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.

    The FAA estimates that this AD affects 1,680 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this AD:
    The FAA has determined that revising the existing maintenance or 
inspection program takes an average of 90 work-hours per operator, 
although the agency recognizes that this number may vary from operator 
to operator. Since operators incorporate maintenance or inspection 
program changes for their affected fleet(s), the FAA has determined 
that a per-operator estimate is more accurate than a per-airplane 
estimate. Therefore, the agency estimates the average total cost per 
operator to be $7,650 (90 work-hours - $85 per work-hour).

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.

(e) Unsafe Condition

    This AD was prompted by a determination that new or more 
restrictive airworthiness limitations are necessary. The FAA is 
issuing this AD to address safety-significant latent failures (that 
are not annunciated), which, in combination with one or more other 
specific failures or events, could result in a hazardous or 
catastrophic failure condition.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.
