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) 
2021-24-20, which apply to all Airbus SAS Model A350-941 and -1041 
airplanes, and AD 2023-03-05, which apply to certain Airbus SAS Model 
A350-941 and -1041 airplanes. AD 2021-24-20 requires repetitive water 
drainage and plug cleaning of the left- and right-hand slat geared 
rotary actuators (SGRAs) having a certain part number installed on slat 
5 track 12 with certain functional item numbers. AD 2023-03-05 requires 
revising the existing maintenance or inspection program, as applicable, 
to incorporate new or more restrictive airworthiness limitations. Since 
the FAA issued AD 2021-24-20 and AD 2023-03-05, the FAA has determined 
that new or more restrictive airworthiness limitations are necessary. 
This proposed AD would continue to require certain actions in AD 2021-
24-20 and AD 2023-03-05 and would require revising the existing 
maintenance or inspection program, as applicable, to incorporate new or 
more restrictive airworthiness limitations, as specified in a European 
Union Aviation Safety Agency (EASA) AD, which is proposed for 
incorporation by reference (IBR). 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 January 29, 
2024.

this proposal because of those comments.
    Except for Confidential Business Information (CBI) as described in 
the following paragraph, and other information as described in 14 CFR 
11.35, the FAA will post all comments received, without change, to 
regulations.gov, including any personal information you provide. The 
agency will also post a report summarizing each substantive verbal 
contact received about this NPRM.

Confidential Business Information

    CBI is commercial or financial information that is both customarily 
and actually treated as private by its owner. Under the Freedom of 
Information Act (FOIA) (5 U.S.C. 552), CBI is exempt from public 
disclosure. If your comments responsive to this NPRM contain commercial 
or financial information that is customarily treated as private, that 
you actually treat as private, and that is relevant or responsive to 
this NPRM, it is important that you clearly designate the submitted 
comments as CBI. Please mark each page of your submission containing 
CBI as ``PROPIN.'' The FAA will treat such marked submissions as 
confidential under the FOIA, and they will not be placed in the public 
docket of this NPRM. Submissions containing CBI should be sent to Dat 
Le, Aviation Safety Engineer, FAA, 1600 Stewart Avenue, Suite 410, 
Westbury, NY 11590; telephone 516-228-7300; email [email protected]. Any commentary that the FAA receives that is not 
specifically designated as CBI will be placed in the public docket for 
this rulemaking.

Background

    The FAA issued AD 2021-24-20, Amendment 39-21841 (86 FR 72838, 
December 23, 2021) (AD 2021-24-20), for all Airbus SAS Model A350-941 
and -1041 airplanes. AD 2021-24-20 was prompted by an MCAI originated 
by EASA, which is the Technical Agent for the Member States of the 
European Union. EASA issued AD 2021-0130R1, dated June 10, 2021 (EASA 
2021-0130R1) (which corresponds to FAA AD

[[Page 86841]]

2021-24-20), to correct an unsafe condition.
    AD 2021-24-20 requires repetitive water drainage and plug cleaning 
of the left- and right-hand SGRAs having a certain part number 
installed on slat 5 track 12 with certain functional item numbers. The 
FAA issued AD 2021-24-20 to address SGRA jams, which could result in 
reduced control of the airplane.
    The FAA also issued AD 2023-03-05, Amendment 39-22330 (88 FR 10011, 
February 16, 2023) (AD 2023-03-05), for certain Airbus SAS Model A350-
941 and -1041 airplanes. AD 2023-03-05 was prompted by an MCAI 
originated by EASA, which is the Technical Agent for the Member States 
of the European Union. EASA issued AD 2022-0127, dated June 28, 2022 
(EASA 2022-0127) (which corresponds to FAA AD 2023-03-05), to correct 
an unsafe condition.
    AD 2023-03-05 requires revising the existing maintenance or 
inspection program, as applicable, to incorporate additional new or 
more restrictive airworthiness limitations. The FAA issued AD 2023-03-
05 to address hazardous or catastrophic airplane system failures. In 
addition, paragraph (m) of AD 2023-03-05 specifies terminating action 
for repetitive greasing of certain thrust reverser actuators required 
by paragraph (g) of AD 2019-20-01, Amendment 39-19754 (84 FR 55495, 
October 17, 2019). This proposed AD would therefore continue to allow 
that terminating action.

Actions Since AD 2021-24-20 and AD 2023-03-05 Were Issued

    Since the FAA issued AD 2021-24-20 and AD 2023-03-05, EASA 
superseded AD 2021-0130R1 and AD 2022-0127 and issued EASA AD 2023-
0157, dated July 31, 2023 (EASA AD 2023-0157) (referred to after this 
as the MCAI), for all Airbus SAS Model A350-941 and -1041 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 June 1, 2023, 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 hazardous or catastrophic 
airplane system failure. You may examine the MCAI in the AD docket at 
regulations.gov under Docket No. FAA-2023-2240.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed EASA AD 2023-0157. This service information 
specifies new or more restrictive airworthiness limitations for 
airplane structures and safe life limits.
    This proposed AD would also require EASA AD 2022-0127, dated June 
28, 2022, which the Director of the Federal Register approved for 
incorporation by reference as of March 23, 2023 (88 FR 10011, February 
16, 2023).
    This proposed AD would also require EASA AD 2021-0130R1, dated June 
10, 2021, which the Director of the Federal Register approved for 
incorporation by reference as of January 27, 2022 (86 FR 72838, 
December 23, 2021).
    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 ADDRESSES.

FAA's Determination

    This product has been approved by the aviation authority of another 
country and is approved for operation in the United States. Pursuant to 
the FAA's bilateral agreement with this 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 the same type design.

Proposed AD Requirements in This NPRM

    This proposed AD would retain certain requirements of AD 2021-24-20 
and AD 2023-03-05. 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 2023-0157 already 
described, as proposed for incorporation by reference. Any differences 
with EASA AD 2023-0157 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 (q)(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 ADs by reference in the FAA final 
rule. This proposed AD would, therefore, require compliance with EASA 
ADs 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 an 
EASA AD 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 2023-0157. Service information required by EASA 
ADs for compliance will be available at regulations.gov by searching 
for and locating Docket No. FAA-2023-2240 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 86842]]

    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 30 airplanes of U.S. registry. The FAA estimates the following 
costs to comply with this proposed AD:

                             Estimated Costs for Retained Actions From AD 2021-24-20
----------------------------------------------------------------------------------------------------------------
                                                                                    Cost per       Cost on U.S.
               Action                        Labor cost           Parts cost        product         operators
----------------------------------------------------------------------------------------------------------------
Retained actions from AD 2021-24-20.  4 work-hours x $85 per               $0             $340          $10,200
                                       hour = $340.
----------------------------------------------------------------------------------------------------------------

    The FAA estimates the total cost per operator for the retained 
actions from AD 2023-03-05 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.
