Abstract
The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus SAS Model A330-200, -200 Freighter, -300, -800, and -900 series airplanes. This proposed AD was prompted by the identification of an incorrect shot peening application implemented in production. This proposed AD would require repetitive special detailed inspections (SDIs) of affected central windshield frames and applicable corrective actions. The FAA is proposing this AD to address the unsafe condition on these products.

Background
EASA, which is the Technical Agent for the Member States of the
European Union, has issued EASA AD 2025-0071, dated March 31, 2025
(EASA AD 2025-0071) (also referred to as the MCAI), to correct an
unsafe condition for certain Airbus SAS Model A330-200, -200 Freighter,
-300, -800, and -900 series airplanes. 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.
The FAA is proposing 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-2025-3988.
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.
FAA's Determination
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 is issuing this NPRM
after determining that the unsafe condition described previously is
likely to exist or develop in other products of the same type design.
Proposed AD Requirements in This NPRM
This proposed AD would require accomplishing the actions specified
in EASA AD 2025-0071 described previously, except for any differences
identified as exceptions in the regulatory text of this proposed AD.
Explanation of Required Compliance Information
In the FAA's ongoing efforts to improve the efficiency of the AD
process, the FAA developed a process to use some civil aviation
authority (CAA) ADs as the primary source of information for compliance
with requirements for corresponding FAA ADs. The FAA has been
coordinating this process with manufacturers and CAAs. As a result, the
FAA proposes to incorporate EASA AD 2025-0071 by reference in the FAA
final rule. This proposed AD would, therefore, require compliance with
EASA AD 2025-0071 in its entirety through that incorporation, except
for any differences identified as exceptions in the regulatory text of
this proposed AD. Using common terms that are the same as the heading
of a particular section in EASA AD 2025-0071 does not mean that
operators need comply only with that section. For example, where the AD
requirement refers to ``all required actions and compliance times,''
compliance with this AD requirement is not limited to the section
titled ``Required Action(s) and Compliance Time(s)'' in EASA AD 2025-
0071. Material required by EASA AD 2025-0071 for compliance will be
available at <a href="http://regulations.gov">regulations.gov</a> under Docket No. FAA-2025-3988 after the
FAA final rule is published.
Costs of Compliance
The FAA estimates that this AD, if adopted as proposed, would
affect 145 airplanes of U.S. registry. The FAA
[[Page 51224]]
estimates the following costs to comply with this proposed AD:
Estimated Costs for Required Actions
--------------------------------------------------------------------------------------------------------------------------------------------------------
Labor cost Parts cost Cost per product Cost on U.S. operators
--------------------------------------------------------------------------------------------------------------------------------------------------------
4 work-hours x $85 per hour = $340......................... $0 $340 $49,300
--------------------------------------------------------------------------------------------------------------------------------------------------------
The FAA has received no definitive data on which to base the cost
estimates for the on-condition repairs specified in this proposed 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
The FAA determined that this proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD would 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 this proposed
regulation:
(1) Is not a ``significant regulatory action'' under Executive
Order 12866,
(2) Would not affect intrastate aviation in Alaska, and
(3) Would not have a significant economic impact, positive or
negative, on a substantial number of small entities under the criteria
of the Regulatory Flexibility Act.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Incorporation by
reference, Safety.
The Proposed Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
0
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
0
2. The FAA amends Sec. 39.13 by adding the following new airworthiness
directive:
Airbus SAS: Docket No. FAA-2025-3988; Project Identifier MCAI-2025-
00443-T.
(a) Comments Due Date
The FAA must receive comments on this airworthiness directive
(AD) by January 2, 2026.
(b) Affected ADs
None.
(c) Applicability
This AD applies to Airbus SAS airplanes identified in paragraphs
(c)(1) through (5) of this AD, certificated in any category, as
identified in European Union Aviation Safety Agency (EASA) AD 2025-
0071, dated March 31, 2025 (EASA AD 2025-0071).
(1) Model A330-201, -202, -203, -223, and -243 airplanes.
(2) Model A330-223F and -243F airplanes.
(3) Model A330-301, -302, -303, -321, -322, -323, -341, -342 and

(4) Model A330-841 airplanes.
(5) Model A330-941 airplanes.
(d) Subject
Air Transport Association (ATA) of America Code 53, Fuselage.
(e) Unsafe Condition
This AD was prompted by the identification of an incorrect shot
peening application that was implemented in production. The FAA is
issuing this AD to address the fatigue life of affected central
windshield frames that might be lower than the certified value. This
condition, if not addressed, could adversely affect the structural
integrity of the airplane.
(f) Compliance
Comply with this AD within the compliance times specified,
unless already done.
(g) Requirements
Except as specified in paragraphs (h) and (i) of this AD: Comply
with all required actions and compliance times specified in, and in
accordance with, EASA AD 2025-0071.
(h) Exceptions to EASA AD 2025-0071
(1) This AD does not adopt the ``Remarks'' section of EASA AD
2025-0071.
(2) Where paragraph (2) of EASA AD 2025-0071 specifies if ``any
crack is found on an affected part, before next flight, contact
Airbus for repair instructions and, within the compliance time
specified in those instructions, accomplish those instructions
accordingly'', this AD requires replacing that text with ``any
cracking is found on an affected part, the cracking must be repaired
before further flight using a method approved by the Manager, AIR-
520, Continued Operational Safety Branch, FAA; or EASA; or Airbus
SAS's EASA Design Organization Approval (DOA). If approved by the
DOA, the approval must include the DOA-authorized signature.''
(i) No Reporting Requirement
Although the material referenced in EASA AD 2025-0071 specifies
to submit certain information to the manufacturer, this AD does not
include that requirement.
(j) Additional AD Provisions
The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager, AIR-
520, Continued Operational Safety Branch, 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 Operational Safety Branch, send it to the attention of the
person identified in paragraph (k) of this AD and email to:

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
accomplished using a method approved by the Manager, AIR-520,
Continued Operational Safety Branch, FAA; or EASA; or Airbus SAS's
EASA Design Organization Approval (DOA). If approved by the DOA, the
approval must include the DOA-authorized signature.
(3) Required for Compliance (RC): Except as required by
paragraph (j)(2) of this AD, if
[[Page 51225]]
any material contains procedures or tests that are identified as RC,
those procedures and tests must be done to comply with this AD; any
procedures or tests that are not identified as RC are recommended.
Those procedures and tests that are not identified as RC may be
deviated from using accepted methods in accordance with the
operator's maintenance or inspection program without obtaining
approval of an AMOC, provided the procedures and tests identified as
RC can be done and the airplane can be put back in an airworthy
condition. Any substitutions or changes to procedures or tests
identified as RC require approval of an AMOC.
