Abstract
The FAA is superseding Airworthiness Directive (AD) 2023-05- 13, which applied to 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). AD 2023-05-13 required revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. Since the FAA issued AD 2023-05-13, the FAA has determined that new or more restrictive airworthiness limitations are necessary. This AD continues to require the actions in AD 2023-05-13 and requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. The FAA is issuing this AD to address the unsafe condition on these products.

AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2023-05-
13, which applied to 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). AD 2023-05-13
required revising the existing maintenance or inspection program, as
applicable, to incorporate new or more restrictive airworthiness
limitations. Since the FAA issued AD 2023-05-13, the FAA has determined
that new or more restrictive airworthiness limitations are necessary.
This AD continues to require the actions in AD 2023-05-13 and requires
revising the existing maintenance or inspection program, as applicable,
to incorporate new or more restrictive airworthiness limitations. The
FAA is issuing this AD to address the unsafe condition on these
products.

SUPPLEMENTARY INFORMATION:
Background
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 to supersede AD 2023-05-13, Amendment 39-22382 (88 FR
20749, April 7, 2023) (AD 2023-05-13). AD 2023-05-13 applied to all
Airbus SAS Model A300-600 series airplanes. AD 2023-05-13 required
revising the existing maintenance or inspection program, as applicable,
to incorporate new or more restrictive airworthiness limitations. The
FAA issued AD 2023-05-13 to address fatigue damage in principal
structural elements.
The NPRM was published in the Federal Register on March 20, 2025
(90 FR 13107). The NPRM was prompted by AD 2024-0164, dated August 21,
2024 (EASA AD 2024-0164) (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 or more restrictive
airworthiness limitations have been developed.
The MCAI also states that EASA revised 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)) to remove Model A300-600 series
airplanes from the applicability. Accomplishing the actions specified
in this AD therefore terminates all requirements of AD 2018-18-19 for
Model A300-600 series airplanes only.
In the NPRM, the FAA proposed to continue to require the actions in
AD 2023-05-13. In the NPRM, the FAA also proposed to require revising
the existing maintenance or inspection program, as applicable, as
specified in EASA AD 2024-0164. The FAA is issuing this AD to address
fatigue damage in principal structural elements.
You may examine the MCAI in the AD docket at <a href="http://regulations.gov">regulations.gov</a> under
Docket No. FAA-2025-0351.
Discussion of Final Airworthiness Directive
Comments
The FAA received comments from two individuals who supported the
NPRM without change.
Request To Confirm Intent To Allow Use of Later-Approved Revisions
ProTech Aero Services Limited requested the FAA confirm that the
proposed AD would allow the use of later-approved revisions of the
material specified in EASA AD 2024-0164, as acceptable for compliance
with the AD requirements.
The FAA confirms that it intends to allow the use of later-approved
revisions of the material referenced in EASA AD 2024-0164 as acceptable
for compliance with the required actions. This AD adopts the ``Ref.
Publications'' section of EASA AD 2024-0164, which includes the current
version of the referenced material as well as later approved variations
or revisions.
Conclusion
These products have been approved by the civil aviation authority
of another country and are approved for operation in the United States.
Pursuant to the FAA's bilateral agreement with this State of Design
Authority, that authority has notified the FAA of the unsafe condition
described in the MCAI referenced above. The FAA reviewed the relevant
data, considered any 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 these products. 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
The FAA reviewed EASA AD 2024-0164, which specifies new or more
restrictive airworthiness limitations for airplane structures and safe
life limits.
This AD also requires EASA AD 2022-0173, dated August 24, 2022,
which the Director of the Federal Register approved for incorporation
by reference as of May 12, 2023 (88 FR 20749, April 7, 2023).
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 estimates the total cost per operator for the retained
actions from AD 2023-05-13 to be $7,650 (90 work-hours x $85 per work-
hour).
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.
The FAA estimates the total cost per operator for the new actions
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
[[Page 51093]]
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.

appropriate principal inspector, or lacking a principal inspector,
the manager of the responsible Flight Standards Office.
(2) Contacting the Manufacturer: For any requirement in this AD
to obtain instructions from a manufacturer, the instructions must be
accomplished using a method approved by the Manager, AIR-520,
Continued Operational Safety Branch, FAA; or EASA; or Airbus SAS's
