SUPPLEMENTARY INFORMATION: DATES: lotter on DSK11XQN23PROD with RULES1 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 A350–941 and –1041 airplanes. The NPRM published in the Federal Register on April 14, 2023 (88 FR 22923). The NPRM was prompted by AD 2023–0004, dated January 6, 2023, issued by EASA, which is the Technical Agent for the Member States of the European Union (EASA AD 2023–0004) (also referred to as the MCAI). The MCAI states that new or more restrictive airworthiness limitations are necessary. EASA AD 2023–0004 specifies that it requires tasks (limitations) already in Airbus A350 Airworthiness Limitations Section (ALS), Part 2, Revision 08, dated May 2, 2022, that is required by EASA VerDate Sep<11>2014 16:10 Jun 30, 2023 Jkt 259001 AD 2022–0125, dated June 28, 2022 (which corresponds to FAA AD 2023– 04–05, Amendment 39–22352 (88 FR 13668, March 6, 2023) (AD 2023–04– 05)), and that incorporation of EASA AD 2023–0004 invalidates (terminates) prior instructions for those tasks. This AD therefore terminates the limitations for the tasks identified in the service information referenced in EASA AD 2023–0004 only, as required by paragraph (j) of AD 2023–04–05. 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 2023–0004. The FAA is issuing this AD to address reduced structural integrity of the airplane. You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA–2023–0927. Discussion of Final Airworthiness Directive Comments The FAA received comments from The 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 2023–0004 describes new or more restrictive airworthiness limitations for airplane structures and safe life limits. 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 31 airplanes of U.S. registry. The PO 00000 Frm 00013 Fmt 4700 Sfmt 4700 42599 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, 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 A350-941 and -1041 airplanes. The NPRM published in the Federal 
Register on April 14, 2023 (88 FR 22923). The NPRM was prompted by AD 
2023-0004, dated January 6, 2023, issued by EASA, which is the 
Technical Agent for the Member States of the European Union (EASA AD 
2023-0004) (also referred to as the MCAI). The MCAI states that new or 
more restrictive airworthiness limitations are necessary.
    EASA AD 2023-0004 specifies that it requires tasks (limitations) 
already in Airbus A350 Airworthiness Limitations Section (ALS), Part 2, 
Revision 08, dated May 2, 2022, that is required by EASA AD 2022-0125, 
dated June 28, 2022 (which corresponds to FAA AD 2023-04-05, Amendment 
39-22352 (88 FR 13668, March 6, 2023) (AD 2023-04-05)), and that 
incorporation of EASA AD 2023-0004 invalidates (terminates) prior 
instructions for those tasks. This AD therefore terminates the 
limitations for the tasks identified in the service information 
referenced in EASA AD 2023-0004 only, as required by paragraph (j) of 
AD 2023-04-05.
    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 
2023-0004. The FAA is issuing this AD to address reduced structural 
integrity of the airplane.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2023-0927.

Comments

    The FAA received comments from The 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 2023-0004 describes new or more restrictive airworthiness 
limitations for airplane structures and safe life limits. 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 31 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 x $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.
