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) 
2016-26-05 and AD 2019-21-02, which apply to certain Airbus SAS Model 
A330-200, A330-200 Freighter, and A330-300 series airplanes. AD 2016-
26-05 and AD 2019-21-02 require revising the existing maintenance or 
inspection program, as applicable, to incorporate new or more 
restrictive airworthiness limitations. Since the FAA issued AD 2016-26-
05 and AD 2019-21-02, the FAA has determined that new or more 
restrictive airworthiness limitations are necessary, and new airplanes 
have been added to the applicability. This proposed AD would continue 
to require the actions in AD 2019-21-02 and require revising the 
existing maintenance or inspection program, as applicable, to 
incorporate additional new or more restrictive airworthiness 
limitations, as specified in a European Union Aviation Safety Agency 
(EASA) AD, which is proposed for incorporation by reference. 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 5, 
2022.

Background

    The FAA issued AD 2019-21-02, Amendment 39-19768 (84 FR 57313, 
October 25, 2019) (AD 2019-21-02), which applies to certain Airbus SAS 
Model A330-200, A330-200 Freighter, and A330-300 series airplanes. AD 
2019-21-02 requires revising the existing maintenance or inspection 
program, as applicable, to incorporate new or more restrictive 
airworthiness limitations. The FAA issued AD 2019-21-02 to address a 
safety-significant latent failure (that is not annunciated) that, in 
combination with one or more other specific failures or events, could 
result in a hazardous or catastrophic failure condition. AD 2019-21-02 
specifies that accomplishing the revision required by that AD 
terminates all requirements of 2016-26-05, Amendment 39-18763 (82 FR 
1170, January 5, 2017) (AD 2016-26-05).

Actions Since AD 2019-21-02 Was Issued

    Since the FAA issued AD 2019-21-02, the FAA has determined that new 
or more restrictive airworthiness limitations are necessary.
    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2021-0248, dated November 15, 2021 
(EASA AD 2021-0248) (also referred to as the MCAI), to correct an 
unsafe condition for all Airbus SAS Model Airbus A330-201, A330-202, 
A330-203, A330-223, A330-223F, A330-243, A330-243F, A330-301, A330-302, 
A330-303, A330-321, A330-322, A330-323, A330-341, A330-342, A330-343, 
A330-841, and A330-941 airplanes.
    Airplanes with an original airworthiness certificate or original 
export certificate of airworthiness issued after July 1, 2021, 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.
    This proposed AD was prompted by a determination that new or more 
restrictive airworthiness limitations are necessary, and that EASA AD 
2021-0248 has added Airbus SAS Model A330-841 and A330-941 airplanes to 
the applicability. The FAA is proposing this AD to address a safety-
significant latent failure (that is not annunciated) that, in 
combination with one or more other specific failures or events, could 
result in a hazardous or catastrophic failure condition. See the MCAI 
for additional background information.

Related Service Information Under 1 CFR Part 51

    EASA AD 2021-0248 describes new or more restrictive airworthiness 
limitations for airplane structures and safe life limits, and adds new 
models to the applicability.
    This proposed AD would also require Airbus A330 Airworthiness 
Limitations Section (ALS) Part 3-Certification Maintenance Requirements 
(CMR), Revision 06, dated October 15, 2018; and Airbus A330 ALS Part 3-
Certification Maintenance Requirements (CMR), Variation 6.1, dated June 
28, 2019; which the Director of the Federal Register approved for 
incorporation by reference as of November 29, 2019 (84 FR 57313, 
October 25, 2019).
    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 aviation authority of 
another country and are approved for operation in the United States. 
Pursuant to the FAA's bilateral agreement with the State of Design 
Authority, it 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 these same type designs.

Proposed AD Requirements in This NPRM

    This proposed AD would retain the requirements of AD 2019-21-02. 
This proposed AD would also require revising the existing maintenance 
or inspection program, as applicable, to incorporate new or more 
restrictive airworthiness limitations, which are specified in EASA AD 
2021-0248 described previously, as proposed for incorporation by 
reference. Any differences with EASA AD 2021-0248 are identified as 
exceptions in the regulatory text of this 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 (l)(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 incorporate EASA AD 2021-0248 by reference in the FAA 
final rule. This proposed AD would, therefore, require compliance with 
EASA AD 2021-0248 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 2021-0248 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 2021-
0248. Service information required by EASA AD 2021-0248 for compliance 
will be available at https://www.regulations.gov by searching for and 
locating Docket No. FAA-2022-0586 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).

[[Page 30842]]

    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 FAA 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 proposed AD affects 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 2019-21-02 to be $7,650 (90 work-hours x $85 per work-
hour).
    The FAA has determined that revising the existing maintenance or 
inspection 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.
    The FAA estimates the total cost per operator for the new proposed 
actions to be $7,650 (90 work-hours x $85 per work-hour).

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
