14 CFR Part 39

[Docket No. FAA-2023-0014; Project Identifier MCAI-2022-01160-T; 
Amendment 39-22382; AD 2023-05-13]

Airworthiness Directives; Airbus SAS Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for all 
Airbus SAS Model A300 B4-600, B4-600R, and F4-600R series airplanes, 
and Model A300 C4-605R Variant F airplanes (collectively called Model 
A300-600 series airplanes). 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 May 12, 2023.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of May 12, 
2023.

ADDRESSES: 
    AD Docket: You may examine the AD docket at regulations.gov under 
Docket No. FAA-2023-0014; or in person at Docket Operations between 9 
a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD

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 
A300-600 series airplanes. The NPRM published in the Federal Register 
on January 13, 2023 (88 FR 2276). The NPRM was prompted by AD 2022-
0173, dated August 24, 2022, issued by EASA, which is the Technical 
Agent for the Member States of the European Union (EASA AD 2022-0173) 
(also referred to as the MCAI). The MCAI states that new or more 
restrictive airworthiness limitations have been developed.
    EASA AD 2022-0173 specifies that it requires a task (limitation) 
related to the replacement of life-limited parts already in Airbus 
A300-600 Airworthiness Limitations Section (ALS) Part 1 Safe Life 
Airworthiness Limitations Items (SL-ALI) Revision 02 that is required 
by EASA AD 2017-0204 (which corresponds to FAA AD 2018-18-19, Amendment 
39-19398 (83 FR 47056, September 18, 2018) (AD 2018-18-19)), and that 
incorporation of EASA AD 2022-0173 invalidates (terminates) prior 
instructions for that task. For Model A300 B4-601, B4-603, B4-620, B4-
622, B4-605R, B4-622R, C4-605R Variant F, F4-605R and F4-622R airplanes 
only: this AD therefore terminates the limitations for the safe life 
limits required by paragraph (g) of AD 2018-18-19, for the tasks 
identified in the service information referenced in EASA AD 2022-0173 
only.
    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 
2022-0173. The FAA is issuing this AD to address fatigue damage in 
principal structural elements. The unsafe condition, if not addressed, 
could result in reduced structural integrity of the airplane.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2023-0014.

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

    The FAA reviewed EASA AD 2022-0173, 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 ADDRESSES.

Costs of Compliance

    The FAA estimates that this AD affects 128 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

[[Page 20750]]

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.
