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, A330-200 Freighter, A330-300, A330-800, and A330-900 
series airplanes. The NPRM was published in the Federal Register on 
February 13, 2025 (90 FR 9520). The NPRM was prompted by AD 2024-0200, 
dated October 21, 2024, issued by EASA, which is the Technical Agent 
for the Member States of the European Union (EASA AD 2024-0200) (also 
referred to as the MCAI). The MCAI states that an

[[Page 41289]]

incorrect shot peening application has been implemented in production 
starting from 2008. Fatigue life of affected parts (certain splice 
fittings) can consequently be lower than the certified value. This 
condition, if not detected and corrected, could adversely affect the 
structural integrity of the airplane.
    In the NPRM, the FAA proposed to require repetitive DET of certain 
splice fittings and, depending on findings, repair, as specified in 
EASA AD 2024-0200. 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-2025-0200.

Discussion of Final Airworthiness Directive

Comments

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

Request To Allow Non-Destructive Testing (NDT)

    Two individual commenters requested that the proposed AD be revised 
to allow NDT techniques, such as ultrasonic or eddy current 
inspections, rather than rely solely on detailed visual inspections. 
The commenters noted that NDT methods are widely used in aviation and 
can detect internal cracks that may not be visible, which reduces the 
risk of undetected structural failures and minimizes aircraft downtime.
    The FAA disagrees with the commenters' requests. EASA, as the state 
of design authority for these airplanes, analyzed the data, considered 
the recommendations of the manufacturer, and determined that detailed 
inspections are adequate to address the unsafe condition. The FAA 
concurs with EASA's determination. The FAA has not changed this AD in 
response to this comment.

Request To Allow a Risk-Based Inspection Schedule

    Two individual commenters suggested that a risk-based inspection 
schedule could optimize resources by allowing airplanes with fewer 
operational hours to undergo inspections at longer intervals. The 
commenters stated that this strategy is used in other airworthiness 
directives and would enhance the proposed rule's effectiveness without 
imposing an excessive burden on operators.
    The FAA disagrees with the commenters' requests. EASA, as the state 
of design authority for these airplanes, performed a risk assessment 
and determined the compliance time was appropriate based on the safety 
implications of the identified unsafe condition, as well as the 
practical aspect of completing the required actions during regular 
maintenance periods. However, the FAA will consider requests for an 
alternative method of compliance (AMOC) as specified in paragraph 
(i)(1) of this AD if sufficient data are submitted to substantiate that 
a risk-based inspection schedule would provide an acceptable level of 
safety. The FAA has not changed this AD in response to 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

    The FAA reviewed EASA AD 2024-0200, which specifies procedures for 
repetitive DET of affected parts (splice fittings at the front 
windshield side post, on left-hand (LH) and right-hand (RH) sides, 
having part number (P/N) F531-23024-200 and P/N F531-23024-201, 
respectively) for cracking, and depending on findings, repairing 
cracking. 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 58 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this AD:

                                      Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
                                                                                    Cost per       Cost on U.S.
                          Labor cost                              Parts cost        product         operators
----------------------------------------------------------------------------------------------------------------
5 work-hours x $85 per hour = $425...........................              $0             $425          $24,650
----------------------------------------------------------------------------------------------------------------

    The FAA has received no definitive data on which to base the cost 
estimates for the on-condition repairs specified in this AD.
    The FAA has included all known costs in its cost estimate. 
According to the manufacturer, however, some or all of the costs of 
this AD may be covered under warranty, thereby reducing the cost impact 
on affected operators.

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

[[Page 41290]]

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.
