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 A330-200, -200 Freighter, -300, -800, and -900 
series airplanes. This AD was prompted by the identification of an 
incorrect shot peening application implemented in production. This AD 
requires repetitive special detailed inspections (SDIs) of affected 
central windshield frames and applicable corrective actions. The FAA is 
issuing this AD to address the unsafe condition on these products.

DATES: This AD is effective July 6, 2026.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of July 6, 
2026.

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 A330-200, -200 Freighter, -300, -800, and -900 series airplanes. 
The NPRM was published in the Federal Register on November 17, 2025 (90 
FR 51222). The NPRM was prompted by AD 2025-0071, dated March 31, 2025 
(EASA AD 2025-0071) (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 an incorrect shot peening application was 
implemented in production and the fatigue life of affected central 
windshield frames could consequently be lower than the certified value. 
This condition, if not addressed, could adversely affect the structural 
integrity of the airplane.
    In the NPRM, the FAA proposed to require repetitive SDIs of 
affected central windshield frames and applicable corrective actions, 
as specified in EASA AD 2025-0071. 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-2025-3988.

Discussion of Final Airworthiness Directive

Comments

    The FAA received a comment from Air Line Pilots Association, 
International (ALPA) who supported the NPRM without change.
    The FAA received additional comments from the Citizens Rulemaking 
Alliance. The following presents the comments received on the NPRM and 
the FAA's response to each comment.

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 to extend the 
comment period at least 60 days. The commenter asserted the FAA has not 
adequately justified use of the good cause exemption.
    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 Comply With the Paperwork Reduction Act (PRA)

    The Citizens Rulemaking Alliance requested that the FAA revise the 
AD to comply with the PRA if reporting is required or remove any 
reporting provisions until PRA requirements are satisfied. If reporting 
is not required, the commenter requested the FAA clarify that in the 
AD.
    The FAA notes paragraph (i) of this AD specifies that reporting is 
not required. If an AD were to require reporting, the preamble of the 
AD would include a paragraph titled ``Paperwork Reduction Act'' that 
would provide the applicable OMB control number, required PRA 
statements, and the estimated time to collect the required information 
(burden). Any costs associated with the reporting requirement would be 
included in the Costs of Compliance section in the preamble of the AD. 
Therefore, 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 11 domestic entities, of which three 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 AD affects a 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 airplane to be $340 (4 work-hours x $85 per work-hour). The 
total cost burden is less than 1 percent of average annual revenue for 
all small entities. 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 add to the 
AD docket the methodology and assumptions supporting the estimated cost 
of the proposed AD and 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, aggregate costs, and 
any assumption that the manufacturer would provide parts free of 
charge.
    In the Costs 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 the requirements of 
this AD can be performed during regularly scheduled maintenance. 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. The 
FAA

[[Page 31879]]

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, 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 2025-0071 specifies procedures for repetitive SDIs (i.e., 
high frequency eddy current inspections) for cracking of the windshield 
central lower framing fillet radius on the left-hand and right-hand 
sides and applicable corrective actions. Corrective actions include 
repair.
    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 85 airplanes of U.S. 
registry. The FAA estimates the following total costs to comply with 
this AD:

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

    The FAA has received no definitive data on which to base the cost 
estimates for the on-condition repairs specified in this AD.

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.
