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. attachment studs on the AFT galley complex for damage (i.e., stress marks, dents, bumps, corrosion, contamination, cracks, and scratches) and correct installation and, depending on findings, replacement of the lower attachment stud. The FAA issued AD 2023–07–13 to address broken lower attachment studs having Part Number (P/N) XP14– 070–007800 on the AFT galley complex. The manufacturer’s investigation indicates that the broken lower attachment studs having P/N XP14– 070–007800 resulted from a hydrogeninduced failure. The unsafe condition, if not addressed, could lead to galley module detachment, resulting in injury to airplane occupants and reduced capacity for emergency evacuation of the airplane. 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 dat.v.le@faa.gov. Any commentary that the FAA receives that is not specifically designated as CBI will be placed in the public docket for this rulemaking. The preamble to AD 2023–07–13 explains that the FAA considers the requirements ‘‘interim action’’ and was considering further rulemaking. The FAA has now determined that further rulemaking is indeed necessary, and this proposed AD follows from that determination. Since the FAA issued AD 2023–07– 13, EASA superseded AD 2022–0196, dated September 20, 2022, and issued EASA AD 2024–0078, dated March 20, 2024 (EASA AD 2024–0078) (also referred to as the MCAI), to correct an unsafe condition for certain Airbus SAS Model A350–941 and –1041 airplanes. The MCAI states that additional airplanes are affected, and that all lower attachment studs having P/N XP14– 070–007800, on the AFT galley complex must be replaced. Broken lower attachment studs on the AFT galley complex, if not addressed, could lead to galley detachment, resulting in injury to airplane occupants and reduced capacity for emergency evacuation 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 regulations.gov under Docket No. FAA–2024–1892. Background The FAA issued AD 2023–07–13, Amendment 39–22415 (88 FR 31169, May 16, 2023) (AD 2023–07–13), for certain Airbus SAS Model A350–941 and –1041 airplanes. AD 2023–07–13 was prompted by an MCAI originated by EASA, which is the Technical Agent for the Member States of the European Union. EASA issued AD 2022–0196, dated September 20, 2022, to correct an unsafe condition. AD 2023–07–13 requires repetitive detailed inspections of the lower VerDate Sep<11>2014 18:02 Jul 22, 2024 Jkt 262001 Actions Since AD 2023–07–13 Was Issued Explanation of Retained Requirements Although this proposed AD does not explicitly restate the requirements of AD 2023–07–13, this proposed AD would retain all of the requirements of AD 2023–07–13. Those requirements are referenced in EASA AD 2024–0078, which, in turn, is referenced in paragraph (g) of this proposed AD. PO 00000 Frm 00019 Fmt 4702 Sfmt 4702 Material Incorporated by Reference Under 1 CFR Part 51 EASA AD 2024–0078 specifies repetitive detailed inspections for damaged and incorrectly installed lower attachment studs having P/N XP14– 070–007800 on the AFT galley complex and, depending on findings, replacement of the lower attachment studs, and eventual replacement of all affected lower attachment studs having P/N XP14–070–007800. The MCAI specifies that replacement of all lower attachment studs having P/N XP14– 070–007800 on all affected AFT galleys constitutes a terminating action for the repetitive detailed inspections. 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 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 require accomplishing the actions specified in EASA AD 2024–0078 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 2024–0078 by reference in the FAA final rule. This proposed AD would, therefore, require compliance with EASA AD 2024–0078 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 E:\FR\FM\23JYP1.SGM 23JYP1 59711 Federal Register / Vol. 89, No. 141 / Tuesday, July 23, 2024 / Proposed Rules ‘‘Required Action(s) and Compliance Time(s)’’ in EASA AD 2024–0078. Material required by EASA AD 2024– 0078 for compliance will be available at regulations.gov under Docket No. FAA– 2024–1892 after the FAA final rule is published. EASA AD 2024–0078 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 Costs of Compliance The FAA estimates that this AD, if adopted as proposed, would affect 13 airplanes of U.S. registry. The FAA estimates the following costs to comply with this proposed AD: ESTIMATED COSTS FOR REQUIRED ACTIONS Action Labor cost Retained actions from AD 2023–07–13 ............. New proposed actions ........................................ 2 work-hours × $85 per hour = $170 ................. 7 work-hours × $85 per hour = $595 ................. ddrumheller on DSK120RN23PROD with PROPOSALS1 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.

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) 
2023-07-13, which applies to certain Airbus SAS Model A350-941 and -
1041 airplanes. AD 2023-07-13 requires repetitive detailed inspections 
of the lower attachment studs on the AFT galley complex and, depending 
on findings, replacement of the lower attachment studs. Since the FAA 
issued AD 2023-07-13, it has been determined that additional airplanes 
are affected, and that all affected parts must be replaced with 
serviceable parts. This proposed AD would continue to require the 
actions in AD 2023-07-13, add airplanes to the applicability, and 
require the replacement of all affected parts, as specified in 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 September 
6, 2024.

ADDRESSES: You may send comments, using the procedures found in 14 CFR 
11.43 and 11.45, by any of the following methods:
     Federal eRulemaking Portal: Go to regulations.gov. Follow 
the instructions for submitting comments.

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 2023-07-13, Amendment 39-22415 (88 FR 31169, May 
16, 2023) (AD 2023-07-13), for certain Airbus SAS Model A350-941 and -
1041 airplanes. AD 2023-07-13 was prompted by an MCAI originated by 
EASA, which is the Technical Agent for the Member States of the 
European Union. EASA issued AD 2022-0196, dated September 20, 2022, to 
correct an unsafe condition.
    AD 2023-07-13 requires repetitive detailed inspections of the lower 
attachment studs on the AFT galley complex for damage (i.e., stress 
marks, dents, bumps, corrosion, contamination, cracks, and scratches) 
and correct installation and, depending on findings, replacement of the 
lower attachment stud. The FAA issued AD 2023-07-13 to address broken 
lower attachment studs having Part Number (P/N) XP14-070-007800 on the 
AFT galley complex. The manufacturer's investigation indicates that the 
broken lower attachment studs having P/N XP14-070-007800 resulted from 
a hydrogen-induced failure. The unsafe condition, if not addressed, 
could lead to galley module detachment, resulting in injury to airplane 
occupants and reduced capacity for emergency evacuation of the 
airplane.

Actions Since AD 2023-07-13 Was Issued

    The preamble to AD 2023-07-13 explains that the FAA considers the 
requirements ``interim action'' and was considering further rulemaking. 
The FAA has now determined that further rulemaking is indeed necessary, 
and this proposed AD follows from that determination.
    Since the FAA issued AD 2023-07-13, EASA superseded AD 2022-0196, 
dated September 20, 2022, and issued EASA AD 2024-0078, dated March 20, 
2024 (EASA AD 2024-0078) (also referred to as the MCAI), to correct an 
unsafe condition for certain Airbus SAS Model A350-941 and -1041 
airplanes. The MCAI states that additional airplanes are affected, and 
that all lower attachment studs having P/N XP14-070-007800, on the AFT 
galley complex must be replaced. Broken lower attachment studs on the 
AFT galley complex, if not addressed, could lead to galley detachment, 
resulting in injury to airplane occupants and reduced capacity for 
emergency evacuation 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 
regulations.gov under Docket No. FAA-2024-1892.

Explanation of Retained Requirements

    Although this proposed AD does not explicitly restate the 
requirements of AD 2023-07-13, this proposed AD would retain all of the 
requirements of AD 2023-07-13. Those requirements are referenced in 
EASA AD 2024-0078, which, in turn, is referenced in paragraph (g) of 
this proposed AD.

Material Incorporated by Reference Under 1 CFR Part 51

    EASA AD 2024-0078 specifies repetitive detailed inspections for 
damaged and incorrectly installed lower attachment studs having P/N 
XP14-070-007800 on the AFT galley complex and, depending on findings, 
replacement of the lower attachment studs, and eventual replacement of 
all affected lower attachment studs having P/N XP14-070-007800. The 
MCAI specifies that replacement of all lower attachment studs having P/
N XP14-070-007800 on all affected AFT galleys constitutes a terminating 
action for the repetitive detailed inspections.
    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

    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 require accomplishing the actions specified 
in EASA AD 2024-0078 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 2024-0078 by reference in the FAA 
final rule. This proposed AD would, therefore, require compliance with 
EASA AD 2024-0078 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

[[Page 59711]]

EASA AD 2024-0078 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 2024-0078. Material required by 
EASA AD 2024-0078 for compliance will be available at regulations.gov 
under Docket No. FAA-2024-1892 after the FAA final rule is published.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 13 airplanes of U.S. registry. The FAA estimates the following 
costs to comply with this proposed AD:

                                      Estimated Costs for Required Actions

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.
