Airworthiness Directives; Airbus SAS Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to supersede Airworthiness Directive (AD) 
2022-18-01, which applies to certain Airbus SAS Model A330-200 series 
airplanes, A330-200 Freighter series airplanes, A330-300 series 
airplanes, Model A330-800 series airplanes, and A330-900 series 
airplanes. AD 2022-18-01 requires revising the existing maintenance or 
inspection program, as applicable, to incorporate new or more 
restrictive airworthiness limitations. Since the FAA issued AD 2022-18-
01, the FAA has determined that new or more restrictive airworthiness 
limitations are necessary. This proposed AD would require revising the 
existing maintenance or inspection program, as applicable, to 
incorporate new or more restrictive airworthiness limitations. The FAA 
is proposing this AD to address the unsafe condition on these products.

DATES: The FAA must receive comments on this proposed AD by July 31, 
2025.

ADDRESSES: You may send comments, using the procedures found in 14 CFR 
11.43 and 11.45, by any of the following methods:

designated as CBI will be placed in the public docket for this 
rulemaking.

Background

    The FAA issued AD 2022-18-01, Amendment 39-22152 (87 FR 54355, 
September 6, 2022) (AD 2022-18-01), for certain Airbus SAS Model A330-
200 series airplanes, A330-200 Freighter series airplanes, A330-300 
series airplanes, A330-800 series airplanes, and A330-900 series 
airplanes. AD 2022-18-01 was prompted by an MCAI originated by EASA, 
which is the Technical Agent for the Member States of the European 
Union. EASA issued AD 2021-0246, dated November 17, 2021 (EASA AD 2021-
0246) (which corresponds to FAA AD 2022-18-01), to correct an unsafe 
condition.
    AD 2022-18-01 requires revising the existing maintenance or 
inspection program, as applicable, to incorporate new or more 
restrictive airworthiness limitations. The FAA issued AD 2022-18-01 to 
address fatigue cracking, accidental damage, or corrosion in

[[Page 25164]]

principal structural elements, and possible failure of certain life-
limited parts, which could result in reduced structural integrity of 
the airplane. This proposed AD would supersede AD 2022-18-01.

Actions Since AD 2022-18-01 Was Issued

    Since the FAA issued AD 2022-18-01, EASA superseded AD 2021-0246R1, 
dated October 12, 2022 (which superseded EASA AD 2021-0246), and issued 
EASA AD 2024-0213, dated November 14, 2024 (EASA AD 2024-0213) (also 
referred to as the MCAI), for all Airbus SAS Model A330-200 series 
airplanes, A330-200 Freighter series airplanes, A330-300 series 
airplanes, A330-800 series airplanes, and A330-900 series airplanes. 
The MCAI states that new or more restrictive airworthiness limitations 
have been developed.
    Airplanes with an original airworthiness certificate or original 
export certificate of airworthiness issued after October 1, 2024, must 
comply with the airworthiness limitations specified as part of the 
approved type design and referenced on the type certificate data sheet; 
this proposed AD therefore does not include those airplanes in the 
applicability.
    The FAA is proposing this AD to address fatigue cracking, 
accidental damage, or corrosion in principal structural elements, and 
possible failure of certain life-limited parts. The unsafe condition, 
if not addressed, could result in reduced structural integrity of the 
airplane. You may examine the MCAI in the AD docket at regulations.gov 
under Docket No. FAA-2025-0925.

Material Incorporated by Reference Under 1 CFR Part 51

    The FAA reviewed EASA AD 2024-0213. This material specifies new or 
more restrictive airworthiness limitations for airplane structures and 
safe life limits.
    This proposed AD would also require EASA AD 2021-0246, which the 
Director of the Federal Register approved for incorporation by 
reference as of October 11, 2022 (87 FR 54355, September 6, 2022).
    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 retain certain requirements of AD 2022-18-
01. This proposed AD would also require revising the existing 
maintenance or inspection program, as applicable, to incorporate 
additional new or more restrictive airworthiness limitations, which are 
specified in EASA AD 2024-0213 already described, as proposed for 
incorporation by reference. Any differences with EASA AD 2024-0213 are 
identified as exceptions in the regulatory text of this proposed AD.
    This proposed AD would require revisions to certain operator 
maintenance documents to include new actions (e.g., inspections). 
Compliance with these actions is required by 14 CFR 91.403(c). For 
airplanes that have been previously modified, altered, or repaired in 
the areas addressed by this proposed AD, the operator may not be able 
to accomplish the actions described in the revisions. In this 
situation, to comply with 14 CFR 91.403(c), the operator must request 
approval for an alternative method of compliance (AMOC) according to 
paragraph (m)(1) 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 retain the incorporation by reference (IBR) of EASA AD 
2021-0246 and incorporate EASA AD 2024-0213 by reference in the FAA 
final rule. This proposed AD would, therefore, require compliance with 
EASA AD 2021-0246 and EASA AD 2024-0213 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 2021-0246 or EASA AD 2024-
0213 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 proposed AD requirement is 
not limited to the section titled ``Required Action(s) and Compliance 
Time(s)'' in EASA AD 2021-0246 or EASA AD 2024-0213. Material required 
by EASA AD 2021-0246 and EASA AD 2024-0213 for compliance will be 
available at regulations.gov by searching for and locating Docket No. 
FAA-2025-0925 after the FAA final rule is published.

Airworthiness Limitation ADs Using the New Process

    The FAA's process of incorporating by reference MCAI ADs as the 
primary source of information for compliance with corresponding FAA ADs 
has been limited to certain MCAI ADs (primarily those with service 
bulletins as the primary source of information for accomplishing the 
actions required by the FAA AD). However, the FAA is now expanding the 
process to include MCAI ADs that require a change to airworthiness 
limitation documents, such as airworthiness limitation sections.
    For these ADs that incorporate by reference an MCAI AD that changes 
airworthiness limitations, the FAA requirements are unchanged. 
Operators must revise the existing maintenance or inspection program, 
as applicable, to incorporate the information specified in the new 
airworthiness limitation document. The airworthiness limitations must 
be followed according to 14 CFR 91.403(c) and 91.409(e).
    The previous format of the airworthiness limitation ADs included a 
paragraph that specified that no alternative actions (e.g., 
inspections) or intervals may be used unless the actions and intervals 
are approved as an AMOC in accordance with the procedures specified in 
the AMOCs paragraph under ``Additional AD Provisions.'' This new format 
includes a ``New Provisions for Alternative Actions and Intervals'' 
paragraph that does not specifically refer to AMOCs, but operators may 
still request an AMOC to use an alternative action or interval.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 138 airplanes of U.S. registry. The FAA estimates the following 
costs to comply with this proposed AD:
    The FAA estimates the total cost per operator for the retained 
actions from AD 2022-18-01 to be $7,650 (90 work-hours x $85 per work-
hour).
    The FAA has determined that revising the existing maintenance or 
inspection

[[Page 25165]]

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.

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.
