Airworthiness Directives; Airbus SAS Airplanes
Publication summary
The FAA is superseding Airworthiness Directive (AD) 2025-03-06 and AD 2025-17-07, which applied to certain Airbus SAS Model A318 and A320 series airplanes; Model A319-111, -112, -113, -114, -115, -131, - 132, -133, -151N, -153N, and -171N airplanes; and Model A321-111, -112, -131, -211, -212, -213, -231, -232, -251N, -251NX, -252N, -252NX, - 253N, -253NX, -271N, -271NX, -272N, and -272NX airplanes. AD 2025-17-07 also applied to Airbus SAS Model A321-253NY airplanes. AD 2025-03-06 and AD 2025-17-07 required revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. Since the FAA issued AD 2025-03- 06 and AD 2025-17-07, new or more restrictive airworthiness limitations have been developed. This AD continues to require certain actions in AD 2025-03-06 and all actions in AD 2025-17-07. This AD also requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations and add new airplane models. The FAA is issuing this AD to address the unsafe condition on these products.

and AD 2025-17-07 required revising the existing maintenance or
inspection program, as applicable, to incorporate new or more
restrictive airworthiness limitations. Since the FAA issued AD 2025-03-
06 and AD 2025-17-07, new or more restrictive airworthiness limitations
have been developed. This AD continues to require certain actions in AD
2025-03-06 and all actions in AD 2025-17-07. This AD also requires
revising the existing maintenance or inspection program, as applicable,
to incorporate new or more restrictive airworthiness limitations and
add new airplane models. 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 2025-03-06, Amendment 39-22954 (90 FR 9595,
February 14, 2025) (AD 2025-03-06); and AD 2025-17-07, Amendment 39-
23117 (90 FR 41771, August 27, 2025) (AD 2025-17-07).
AD 2025-03-06 applied to certain Airbus SAS Model A318 and A320
series airplanes; Model A319-111, -112, -113, -114, -115, -131, -132, -
133, -151N, -153N, and -171N airplanes; and Model A321-111, -112, -131,
-211, -212, -213, -231, -232, -251N, -251NX, -252N, -252NX, -253N, -
253NX, -271N, -271NX, -272N, and -272NX airplanes. AD 2025-03-06
required revising the existing maintenance or inspection program, as
applicable, to
[[Page 25093]]
incorporate new or more restrictive airworthiness limitations
(specified in Airbus A318/A319/A320/A321 Airworthiness Limitations
Section (ALS) Part 2, Damage Tolerant Airworthiness Limitation Items
(DT-ALI), Revision 10, Issue 02, dated November 30, 2023). The FAA
issued AD 2025-03-06 to address fatigue cracking, accidental damage, or
corrosion in principal structural elements, which could result in
reduced structural integrity of the airplane.
AD 2025-17-07 applied to certain Airbus SAS Model A318, A320, and
A321 series airplanes; and Model A319-111, -112, -113, -114, -115, -
131, -132, -133, -151N, -153N, and -171N airplanes. AD 2025-17-07
required revising the existing maintenance or inspection program, as
applicable, to incorporate new airworthiness limitations (specified in
Airbus A318/A319/A320/A321 ALS Part 2, Damage Tolerant Airworthiness
Limitation Items (DT-ALI), Variation 10.3, dated August 7, 2024). The
FAA issued AD 2025-17-07 to address fatigue cracking, accidental
damage, or corrosion in principal structural elements, which could
result in reduced structural integrity of the airplane.
The NPRM was published in the Federal Register on November 17, 2025
(90 FR 51218). The NPRM was prompted by EASA 2025-0030, dated February
10, 2025 (EASA AD 2025-0030) (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 new or more restrictive airworthiness
limitations have been developed, as specified in Airbus A318/A319/A320/
A321 ALS Part 2, Damage Tolerant Airworthiness Limitation Items (DT-
ALI), Revision 11, dated November 4, 2024.
In the NPRM, the FAA proposed to continue to require certain
actions in AD 2025-03-06 and all actions in AD 2025-17-07, as specified
in EASA 2025-0030. The FAA also proposed to require revising the
existing maintenance or inspection program, as applicable, to
incorporate new or more restrictive airworthiness limitations and add
new airplane models. The FAA is issuing this AD to address the unsafe
condition on these products.
You may examine the MCAI in the AD docket at regulations.gov under
Docket No. FAA-2025-3989.
Discussion of Final Airworthiness Directive
Comments
The FAA received comments from United Airlines who supported the
NPRM without change.
The FAA received additional comments from Delta Air Lines (Delta)
and the Citizens Rulemaking Alliance. The following presents the
comments received on the NPRM and the FAA's response to each comment.
Request To Use Previously Approved Alternative Methods of Compliance
(AMOCs)
Delta requested the FAA revise paragraph (p) of the proposed AD to
specify that AMOCs approved previously for AD 2025-03-06 are approved
as AMOCs for the corresponding provisions of EASA AD 2025-0030 that
would be required by paragraph (m) of the proposed AD. Delta stated
that a modification incorporated under a certain supplemental type
certificate prevents accomplishment of certain ALI inspections, but
previously approved AMOCs provide an acceptable level of safety for
those ALI inspections.
The FAA agrees and has added paragraph (p)(1)(ii) to this AD,
accordingly.
Request To Justify Forgoing Notice and Comment or Issue an NPRM
The Citizens Rulemaking Alliance requested that the FAA either
provide its justification for finding good cause to bypass notice and
comment procedures, or convert this action to an NPRM and delay
enforcement until the comment period is complete. The commenter
asserted the FAA has not adequately justified use of the good cause
exemption to bypass notice and comment and the 30-day delayed effective
date.
The FAA notes the comment was submitted in response to an NPRM for
which the FAA provided a 45-day comment period. This final rule is
effective 35 days after its publication in the Federal Register.
Therefore, no change to this AD is necessary.
Request To Make Incorporation by Reference (IBR) Materials Reasonably
Available
The Citizens Rulemaking Alliance requested that the FAA make IBR
material available and free to the public during the comment period.
The FAA clarifies that this AD incorporates by reference EASA AD
2025-0030, not the manufacturer service information referenced in that
EASA AD. The FAA posted EASA AD 2025-0030 to the AD docket when the
NPRM was published in the Federal Register. The FAA notes this AD also
retains EASA AD 2024-0208, dated October 25, 2024 (for the actions
retained from FAA AD 2025-17-07), and EASA AD 2024-0031, dated January
31, 2024; corrected February 1, 2024 (for the actions retained from FAA
AD 2025-03-06), which were previously approved for incorporation by
reference. That material is available under Docket No. FAA-2025-0748
and Docket No. FAA-2024-2145, respectively. The material referenced in
EASA AD 2025-0030 may only be posted before the final rule's
publication if it is already publicly available or if there is written
consent from the owner of that material. Additionally, the FAA provided
notice in the NPRM that the material referenced in EASA AD 2025-0030
will be available in the AD docket after this AD is published. The FAA
did not change this AD as a result of this comment.
Request To Consider Impact on Small Entities
The Citizens Rulemaking Alliance requested that the FAA either
provide the factual basis for its Regulatory Flexibility Act (RFA)
certification that the AD will not have a significant economic impact
on a substantial number of small entities, or prepare an initial
regulatory flexibility analysis.
The FAA provides the following clarification. The RFA of 1980 (5
U.S.C. 601-612), as amended by the Small Business Regulatory
Enforcement Fairness Act of 1996 (Pub. L. 104-121) and the Small
Business Jobs Act of 2010 (Pub. L. 111-240), requires Federal agencies
to consider the effects of the regulatory action on small business and
other small entities and to minimize any significant economic impact.
The term ``small entities'' comprises small businesses and not-for-
profit organizations that are independently owned and operated and are
not dominant in their fields, and governmental jurisdictions with
populations of less than 50,000.
This AD will affect 23 domestic entities, of which 8 are small
entities. The table below displays the industries of the small
entities, their average annual revenue, and the AD's estimated cost
burden relative to average annual revenue.
[[Page 25094]]

Equipment Rental and
Leasing.
----------------------------------------------------------------------------
Total.......................... ........................... 8 32,319,283 0.02
----------------------------------------------------------------------------------------------------------------
While the FAA has determined that this final AD affects a
substantial number of small entities, the compliance cost of the AD
relative to each small entity's annual revenue is minimal. The FAA
estimates the total cost per affected entity to be $7,650 (90 work-
hours x $85 per work-hour), which is 0.02% of the average small
entity's annual revenue. Therefore, as provided in section 605(b), the
FAA certifies this AD will not result in a significant economic impact
on a substantial number of small entities. The FAA did not change this
AD as a result of this comment.
Request To Provide Additional Cost Information
The Citizens Rulemaking Alliance requested that the FAA reassess
the estimated cost of the proposed AD and whether the action is
``significant'' under E.O. 12866. The Citizens Rulemaking Alliance also
requested the FAA reopen the comment period for public input on the
additional cost information. The commenter stated that the FAA should
also provide the fleet size, per airplane labor and parts cost, any
assumed downtime or out-of-service impacts, and aggregate costs.
In the Cost of Compliance section of the proposed AD, the FAA
disclosed the number of airplanes affected on the U.S. registry,
estimated number of work hours provided by the manufacturer, and the
aggregate costs. The FAA did not disclose an estimated parts cost since
this AD does not require any parts. Additionally, the FAA considered
the impact that this AD will have on affected operators and determined
this AD will not trigger any downtime costs because revising the
existing maintenance or inspection program, as applicable, is an
administrative action that can be performed without impacting
operations. Since the FAA has assessed and disclosed the total known
costs of the AD requirements in the Costs of Compliance section of the
proposed AD, and the commenter did not provide additional cost data for
the FAA to consider in its cost analysis, it is not necessary to reopen
the comment period or provide additional information in the AD docket.
Based upon the analysis provided throughout the proposed AD and in the
previous comment response, the FAA certifies that this AD is not a
``significant regulatory action'' under Executive Order 12866. The FAA
did not change this AD as a result of this comment.
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, and any other changes described previously,
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 EASA AD 2025-0030, which specifies new or
more restrictive airworthiness limitations for airplane structures and
safe life limits.
This AD also requires EASA AD 2024-0208, which the Director of the
Federal Register approved for incorporation by reference as of October
1, 2025 (90 FR 41771, August 27, 2025).
This AD also requires EASA AD 2024-0031, which the Director of the
Federal Register approved for incorporation by reference as of March
21, 2025 (90 FR 9595, February 14, 2025).
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 1,900 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 2025-03-06 to be $7,650 (90 work-hours x $85 per work-
hour).
The FAA estimates the total cost per operator for the retained
actions from AD 2025-17-07 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. Therefore, the FAA estimates the average 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
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
[[Page 25095]]
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.
