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.

Airworthiness Directives; Airbus SAS Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

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.

DATES: This AD is effective June 12, 2026.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of June 12, 
2026.
    The Director of the Federal Register approved the incorporation by 
reference of a certain other publication listed in this AD as of 
October 1, 2025 (90 FR 41771, August 27, 2025).
    The Director of the Federal Register approved the incorporation by 
reference of a certain other publication listed in this AD as of March 
21, 2025 (90 FR 9595, February 14, 2025).

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.

    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.

    This paragraph restates the requirements of paragraph (i) of AD 
2025-17-07, with a new exception. Except as required by paragraph 
(m) of this AD, after the existing maintenance or inspection program

required actions and compliance times specified in, and in 
accordance with, EASA AD 2025-0030, dated February 10, 2025 (EASA AD

as applicable, within 90 days after the effective date of this AD.
    (3) The initial compliance time for doing the tasks specified in 
paragraph (3) of EASA AD 2025-0030 is at the applicable ``associated 
thresholds'' as incorporated by the requirements of paragraph (3) of 
EASA AD 2025-0030, or within 90 days after the effective date of 
this AD, whichever occurs later.
    (4) This AD does not adopt the provisions specified in

Tolerant--Airworthiness Limitations Items--tasks beyond MPPT,'' of 
``the ALS'' specified in EASA AD 2025-0030.

(o) New Provisions for Alternative Actions, Intervals, and CDCCLs

    After the existing maintenance or inspection program has been 
revised as required by paragraph (m) of this AD, no alternative

unless they are approved as specified in the provisions of the 
``Ref. Publications'' section of EASA AD 2025-0030.
