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 A320-211, -212, -214, -216, -231, -232, and -233 airplanes; and 
Model A321-111, -112, -131, -211, -212, -213, -231, and -232 airplanes. 
The NPRM was published in the Federal Register on May 4, 2026 (91 FR 
23922). The NPRM was prompted by EASA AD 2025-0193, dated September 8, 
2025 (EASA AD 2025-0193) (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 during a fatigue test on a Model 
A320 airplane in support of the extended service goal (ESG) campaign, 
cracks were identified in the area of fastener holes at the forward and 
aft upper corner of the bulk cargo door at section 16 and 17, both 
left-hand (LH) and right-hand (RH) sides. This condition, if not 
addressed, could affect the structural integrity of the airplane.
    In the NPRM, the FAA proposed to require a rototest inspection for 
cracks and applicable on-condition actions, as specified in EASA AD 
2025-0193. The FAA is issuing this AD to address the unsafe condition 
on these products.
    You may examine the MCAI in the AD docket at <a href="http://regulations.gov">regulations.gov</a> under 
Docket No. FAA-2026-3879.

Discussion of Final Airworthiness Directive

Comments

    The FAA received and reviewed a comment that did not include a 
specific request to change the AD. This comment is outside the scope of 
this AD.

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

[[Page 55251]]

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

    EASA AD 2025-0193 specifies procedures for a rototest inspection 
for cracks in the area of the fastener holes at the forward and aft 
upper corner of the bulk cargo door at section 16 and 17, both LH and 
RH sides, and applicable on-condition actions. On-condition actions 
include contacting the manufacturer for repair instructions and doing 
the repair if cracks are detected, or modifying the affected area by 
cold working the fastener holes if no crack is detected.
    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 1,069 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with 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.

must include the DOA-authorized signature''.
    (4) This AD does not adopt the ``Remarks'' section of EASA AD 
2025-0193.

(i) Additional AD Provisions

    The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager, AIR-
520, FAA, has the authority to approve AMOCs for this AD, if 
requested using the procedures found in 14 CFR 39.19. In accordance 
with 14 CFR 39.19, send your request to your principal inspector or 
responsible Flight Standards Office, as appropriate. If sending 
information directly to the manager of the Continued Operational 
Safety Branch, send it to the attention of the person identified in 
paragraph (j) of this AD and email to: <a href="/cdn-cgi/l/email-protection#387975777b785e5959165f574e"><span class="__cf_email__" data-cfemail="094844464a496f6868276e667f">[email&#160;protected]</span></a>. Before using 
any approved AMOC, notify your 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
