14 CFR Part 39
[Docket No. FAA-2024-2421; Project Identifier MCAI-2024-00221-T;
Amendment 39-22973; AD 2025-05-01]
RIN 2120-AA64
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
certain 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 April 15, 2025.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of April 15,
2025.

AD Docket: You may examine the AD docket at regulations.gov under
Docket No. FAA-2024-2421; or in person at Docket Operations between 9

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 A300-600 series airplanes. The NPRM published in the Federal
Register on November 7, 2024 (89 FR 88174). The NPRM was prompted by AD
2024-0083, dated April 9, 2024, issued by EASA, which is the Technical
Agent for the Member States of the European Union (EASA AD 2024-0083)
(also referred to as the MCAI). The MCAI states that new or more
restrictive airworthiness limitations have been developed.
EASA AD 2024-0083 specifies that it requires a task (limitation)
already in Airbus A300-600 Airworthiness Limitations Section (ALS) Part
2 Revision 4 that is required by EASA AD 2024-0009 (which corresponds
to FAA AD 2024-16-02, Amendment 39-22808 (89 FR 75464, September 16,
2024) (AD 2024-16-02)), and that incorporation of EASA AD 2024-0083
invalidates (terminates) prior instructions for that task. This AD,
therefore, terminates the limitations required by paragraph (dd) of AD
2024-16-02 for the tasks identified in the material referenced in EASA
AD 2024-0083 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
2024-0083. The FAA is issuing this AD to address fatigue cracking,
damage, and corrosion 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-2024-2421.

Discussion of Final Airworthiness Directive
Comments
The FAA received comments from the Air Line Pilots Association,
International (ALPA) supported the NPRM without change.
The FAA also received comments from FedEx, who supported the NPRM
and had additional comments. The following presents the comments
received on the NPRM and the FAA's response to each comment.
Request To Supersede AD 2024-16-02
FedEx requested that the proposed AD be revised to supersede AD
2024-16-02 so that only one AD tracks the requirements in Airbus A300-
600 ALS Part 2 Revision 4, Variation 4.1, dated January 10, 2024.
The FAA disagrees with the commenter's request. This AD requires
complying with EASA AD 2024-0083, which requires incorporating Airbus
A300-600 ALS Part 2 Revision 4, Variation 4.1, not the full Airbus
A300-600 ALS Part 2, Revision 4 document. Additionally, EASA AD 2024-
0083 does not supersede EASA AD 2024-0009. Therefore, this AD does not
supersede AD 2024-16-02, but instead terminates the corresponding
requirements of AD 2024-16-02 for the tasks identified in the material
referenced in EASA AD 2024-0083 only.
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.
Material Incorporated by Reference Under 1 CFR Part 51
EASA AD 2024-0083 specifies new 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 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
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.
