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 proposed for incorporation by reference (IBR). The FAA is issuing this AD to address the unsafe condition on these products.

DATES:

This AD is effective September 25, 2024.

The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of September 25, 2024.

ADDRESSES:

AD Docket: You may examine the AD docket at regulations.gov under Docket No. FAA-2024-1286; or in person at Docket Operations between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays.

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 May 1, 2024 (89 FR 35015). The NPRM was prompted by AD 2024-0003, dated January 5, 2024, issued by EASA, which is the Technical Agent for the Member States of the European Union (EASA AD 2024-0003) (also referred to as the MCAI). The MCAI states that new or more restrictive airworthiness limitations have been developed.

EASA AD 2024-0003 specifies that it requires a task (limitation) already in Airbus A300-600 ALS Part 4 Revision 03 that is required by EASA AD 2017-0202 (which corresponds to FAA AD 2018-18-21, Amendment 39-19400 (83 FR 47054, September 18, 2018) (AD 2018-18-21)), and that incorporation of EASA AD 2024-0003 invalidates (terminates) prior instructions for that task. For Model A300 B4-601, B4-603, B4-620, B4-622, B4-605R, B4-622R, 300 F4-605R, F4-622R, and A300 C4-605R Variant F airplanes only, this AD therefore terminates the limitations required by paragraph (g) of AD 2018-18-21 for the tasks identified in the service information referenced in EASA AD 2017-0202 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 2024-0003. The FAA is issuing this AD to address the risks associated with the effects of aging on airplane systems. The unsafe ( print page 67531) condition, if not addressed, could result in an increased potential for failure of certain life-limited parts, and reduced structural integrity or controllability of the airplane.

You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA-2024-1286.

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.

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 Material Under 1 CFR Part 51

The FAA reviewed EASA AD 2024-0003, which specifies 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 120 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.
