The purpose of these notices is to give interested persons an opportunity to participate in the rule making prior to the adoption of the final rules. DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA–2024–1694; Project Identifier MCAI–2024–00016–T] RIN 2120–AA64 Airworthiness Directives; Airbus SAS Airplanes Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). AGENCY: The FAA proposes to supersede Airworthiness Directive (AD) 2023–12–03 and AD 2023–04–05, which apply to certain Airbus SAS Model A350–941 and –1041 airplanes. AD 2023–12–03 and AD 2023–04–05 require revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. Since the FAA issued AD 2023–12–03 and AD 2023–04–05, the FAA has determined that new or more restrictive airworthiness limitations are necessary. This proposed AD would continue to require all actions in AD 2023–12–03 and certain actions in AD 2023–04–05 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 August 12, 2024.

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 2023–12–03, Amendment 39–22461 (88 FR 42598, July 3, 2023; corrected August 7, 2023 (88 FR 52024)) (AD 2023–12–03), for certain Airbus SAS Model A350–941 and –1041 airplanes. AD 2023–12–03 was prompted by an MCAI originated by EASA, which is the Technical Agent for the Member States of the European Union. EASA issued AD 2023–0004, dated January 6, 2023 (EASA AD 2023– 0004) (which corresponds to FAA AD 2023–12–03), to correct an unsafe condition. AD 2023–12–03 requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. The FAA issued AD 2023– 12–03 to address reduced structural integrity of the airplane. AD 2023–12– 03 specifies that accomplishing the E:\FR\FM\26JNP1.SGM 26JNP1 Federal Register / Vol. 89, No. 123 / Wednesday, June 26, 2024 / Proposed Rules revision required by that AD terminates certain requirements of AD 2023–04–05, Amendment 39–22352 (88 FR 13668, March 6, 2023) (AD 2023–04–05). This proposed AD would therefore continue to allow that terminating action. AD 2023–04–05 corresponds to EASA AD 2022–0125, dated June 28, 2022 (EASA AD 2022–0125) and requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. The FAA issued AD 2023– 04–05 to address reduced structural integrity of the airplane. ddrumheller on DSK120RN23PROD with PROPOSALS1 Actions Since ADs 2023–12–03 and 2023–04–05 Were Issued Since the FAA issued ADs 2023–12– 03 and 2023–04–05, EASA superseded ADs 2023–0004 and 2022–0125 and issued EASA AD 2024–0005, dated January 5, 2024 (EASA AD 2024–0005) (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 November 30, 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 reduced structural integrity of the airplane. You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA– 2024–1694. Related Service Information Under 1 CFR Part 51 The FAA reviewed EASA AD 2024– 0005. 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 2023–0004, which the Director of the Federal Register approved for incorporation by reference as of August 7, 2023 (88 FR 42598, July 3, 2023; corrected August 7, 2023 (88 FR 52024)). This proposed AD would also require EASA 2022–0125, which the Director of the Federal Register approved for incorporation by reference as of April 10, 2023 (88 FR 13668, March 6, 2023). 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. VerDate Sep<11>2014 17:00 Jun 25, 2024 Jkt 262001 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 all requirements of AD 2023–12–03 and certain requirements of AD 2023–04–05. 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 2024– 0005 already described, as proposed for incorporation by reference. Any differences with EASA AD 2024–0005 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 retain the IBR of EASA AD 2022–0125 and EASA AD 2023–0004 and incorporate EASA AD 2024–0005 by reference in the FAA final rule. This proposed AD would, therefore, require compliance with EASA AD 2022–0125, EASA AD 2023–0004, and EASA AD 2024–0005 through that incorporation, PO 00000 Frm 00002 Fmt 4702 Sfmt 4702 53365 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 2022– 0125, EASA AD 2023–0004, or EASA AD 2024–0005 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 2024–0005. Service information required by EASA AD 2024–0005 for compliance will be available at regulations.gov by searching for and locating Docket No. FAA–2024– 1694 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 31 airplanes of U.S. registry. The FAA E:\FR\FM\26JNP1.SGM 26JNP1 53366 Federal Register / Vol. 89, No. 123 / Wednesday, June 26, 2024 / Proposed Rules estimates the following costs to comply with this proposed AD: The FAA estimates the total cost per operator for the retained actions from AD 2023–12–03 to be $7,650 (90 workhours × $85 per work-hour). The FAA has determined that revising the existing maintenance or inspection program takes an average of 90 workhours 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 × $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. ddrumheller on DSK120RN23PROD with PROPOSALS1 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 VerDate Sep<11>2014 17:00 Jun 25, 2024 Jkt 262001 under the criteria of the Regulatory Flexibility Act.

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) 
2023-12-03 and AD 2023-04-05, which apply to certain Airbus SAS Model 
A350-941 and -1041 airplanes. AD 2023-12-03 and AD 2023-04-05 require 
revising the existing maintenance or inspection program, as applicable, 
to incorporate new or more restrictive airworthiness limitations. Since 
the FAA issued AD 2023-12-03 and AD 2023-04-05, the FAA has determined 
that new or more restrictive airworthiness limitations are necessary. 
This proposed AD would continue to require all actions in AD 2023-12-03 
and certain actions in AD 2023-04-05 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 August 12, 
2024.

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

SUPPLEMENTARY INFORMATION:

Comments Invited

    The FAA invites you to send any written relevant data, views, or 
arguments about this proposal. Send your comments to an address listed 
under ADDRESSES. Include ``Docket No. FAA-2024-1694; Project Identifier 
MCAI-2024-00016-T'' at the beginning of your comments. The most helpful 
comments reference a specific portion of the proposal, explain the 
reason for any recommended change, and include supporting data. The FAA 
will consider all comments received by the closing date and may amend 
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 516-228-7317; 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 2023-12-03, Amendment 39-22461 (88 FR 42598, July 
3, 2023; corrected August 7, 2023 (88 FR 52024)) (AD 2023-12-03), for 
certain Airbus SAS Model A350-941 and -1041 airplanes. AD 2023-12-03 
was prompted by an MCAI originated by EASA, which is the Technical 
Agent for the Member States of the European Union. EASA issued AD 2023-
0004, dated January 6, 2023 (EASA AD 2023-0004) (which corresponds to 
FAA AD 2023-12-03), to correct an unsafe condition.
    AD 2023-12-03 requires revising the existing maintenance or 
inspection program, as applicable, to incorporate new or more 
restrictive airworthiness limitations. The FAA issued AD 2023-12-03 to 
address reduced structural integrity of the airplane. AD 2023-12-03 
specifies that accomplishing the

[[Page 53365]]

revision required by that AD terminates certain requirements of AD 
2023-04-05, Amendment 39-22352 (88 FR 13668, March 6, 2023) (AD 2023-
04-05). This proposed AD would therefore continue to allow that 
terminating action. AD 2023-04-05 corresponds to EASA AD 2022-0125, 
dated June 28, 2022 (EASA AD 2022-0125) and requires revising the 
existing maintenance or inspection program, as applicable, to 
incorporate new or more restrictive airworthiness limitations. The FAA 
issued AD 2023-04-05 to address reduced structural integrity of the 
airplane.

Actions Since ADs 2023-12-03 and 2023-04-05 Were Issued

    Since the FAA issued ADs 2023-12-03 and 2023-04-05, EASA superseded 
ADs 2023-0004 and 2022-0125 and issued EASA AD 2024-0005, dated January 
5, 2024 (EASA AD 2024-0005) (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 November 30, 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 reduced structural 
integrity of the airplane. You may examine the MCAI in the AD docket at 
regulations.gov under Docket No. FAA-2024-1694.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed EASA AD 2024-0005. 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 2023-0004, which the 
Director of the Federal Register approved for incorporation by 
reference as of August 7, 2023 (88 FR 42598, July 3, 2023; corrected 
August 7, 2023 (88 FR 52024)).
    This proposed AD would also require EASA 2022-0125, which the 
Director of the Federal Register approved for incorporation by 
reference as of April 10, 2023 (88 FR 13668, March 6, 2023).
    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 all requirements of AD 2023-12-03 and 
certain requirements of AD 2023-04-05. 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 2024-0005 
already described, as proposed for incorporation by reference. Any 
differences with EASA AD 2024-0005 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 retain the IBR of EASA AD 2022-0125 and EASA AD 2023-
0004 and incorporate EASA AD 2024-0005 by reference in the FAA final 
rule. This proposed AD would, therefore, require compliance with EASA 
AD 2022-0125, EASA AD 2023-0004, and EASA AD 2024-0005 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 2022-0125, 
EASA AD 2023-0004, or EASA AD 2024-0005 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 2024-
0005. Service information required by EASA AD 2024-0005 for compliance 
will be available at regulations.gov by searching for and locating 
Docket No. FAA-2024-1694 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 31 airplanes of U.S. registry. The FAA

[[Page 53366]]

estimates the following costs to comply with this proposed AD:
    The FAA estimates the total cost per operator for the retained 
actions from AD 2023-12-03 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.
