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 2022–24–05, Amendment 39–22245 (87 FR 74291, December 5, 2022) (AD 2022–24–05), for all Airbus SAS Model A318–111, –112, –121, and –122 airplanes; Model A319– 111, –112, –113, –114, –115, –131, –132, –133, –151N, –153N, and –171N airplanes; Model A320–211, –212, –214, –216, –231, –232, –233, –251N, –252N, –253N, –271N, –272N, and –273N airplanes; and Model A321–111, –112, –131, –211, –212, –213, –231, –232, –251N, –251NX, –252N, –252NX, –253N, –253NX, –271N, –271NX, –272N, and –272NX airplanes. AD 2022–24–05 was prompted by an MCAI VerDate Sep<11>2014 16:31 Jul 16, 2024 Jkt 262001 58087 originated by EASA, which is the Technical Agent for the Member States of the European Union. EASA issued AD 2021–0183R1, dated September 20, 2021, to correct an unsafe condition. AD 2022–24–05 requires repetitive inspections of certain galleys for corrosion of trolley retainer aluminum blocks and delamination of the upper panel of the trolley compartment, and applicable corrective actions. The FAA issued AD 2022–24–05 to address damage that could affect the galley’s capability to hold the trolley under emergency landing loads, which could lead to trolley detachment, possibly resulting in blocking of an escape path during an emergency exit. • Corrective actions including repeating the inspection at an earlier interval, repairing the trolley compartment upper panel, and limiting the trolley weight; • Procedures for modifying the affected galleys as optional terminating action for the repetitive inspections; • A revised the list of affected galleys; and • Prohibition of the installation of affected parts unless the parts are inspected and corrected. 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. Actions Since AD 2022–24–05 Was Issued 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. Since the FAA issued AD 2022–24– 05, EASA superseded EASA AD 2021– 0183R1, dated September 20, 2021, and issued EASA AD 2024–0038, dated February 5, 2024 (EASA AD 2024–0038) (also referred to as the MCAI), to correct an unsafe condition for all Airbus SAS Model A318, A319, A320, and A321 series airplanes. EASA AD 2024–0038 states that the list of affected galleys has been revised, and Airbus and the galley manufacturer have developed a modification to restore the design integrity of the affected galleys. The FAA is proposing this AD to detect and correct damage that could affect the galley’s capability to hold the trolley under emergency landing loads, which could lead to trolley detachment, possibly resulting in blocking of an escape path during an emergency exit. 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–2024–1890. Explanation of Retained Requirements Although this proposed AD does not explicitly restate the requirements of AD 2022–24–05, this proposed AD would retain all of the requirements of AD 2022–24–05. Those requirements are referenced in EASA AD 2024–0038, which, in turn, is referenced in paragraph (g) of this proposed AD. Material Incorporated by Reference Under 1 CFR Part 51 EASA AD 2024–0038 includes the following provisions: • Procedures for repetitive general visual inspections of certain galleys for discrepancies including corrosion of trolley retainer aluminum blocks and delamination of upper panel of trolley compartment; PO 00000 Frm 00008 Fmt 4702 Sfmt 4702 Proposed AD Requirements in This NPRM This proposed AD would require accomplishing the actions specified in EASA AD 2024–0038 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 2024–0038 by reference in the FAA final rule. This proposed AD would, therefore, require compliance with EASA AD 2024–0038 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 2024–0038 does not mean that operators need comply only with that section. For example, where the AD requirement refers to ‘‘all required E:\FR\FM\17JYP1.SGM 17JYP1 58088 Federal Register / Vol. 89, No. 137 / Wednesday, July 17, 2024 / Proposed Rules 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 2024–0038. Material required by EASA AD 2024– 0038 for compliance will be available at regulations.gov under Docket No. FAA– 2024–1890 after the FAA final rule is published. Costs of Compliance The FAA estimates that this AD, if adopted as proposed, would affect 1,425 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 Parts cost Cost per product Cost on U.S. operators Retained actions from AD 2022-24-05 ............... 2 work-hours × $85 per hour = $170 per hour .. $0 $170 $242,250 ESTIMATED COSTS FOR OPTIONAL ACTIONS Labor cost Parts cost Up to 40 work-hours × $85 per hour = $3,400 ............................................................................................... (*) Cost per product Up to $3,400.* * The FAA has received no definitive data on which to base the cost estimates for the parts associated with the modification specified in this proposed AD. The FAA estimates the following costs to do any necessary on-condition actions that would be required based on the results of any required actions. The FAA has no way of determining the number of aircraft that might need these on-condition actions: ESTIMATED COSTS OF ON-CONDITION ACTIONS Labor cost Parts cost Cost per product 1 work-hour × $85 per hour = $85 ...................................................................................................................... $0 $85 The FAA has included all known costs in its cost estimate. According to the manufacturer, however, some or all of the costs of this proposed AD may be covered under warranty, thereby reducing the cost impact on affected operators. 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. VerDate Sep<11>2014 16:31 Jul 16, 2024 Jkt 262001 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. The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: PO 00000 Frm 00009 Fmt 4702 Sfmt 4702 PART 39—AIRWORTHINESS DIRECTIVES 1.

(2) Where EASA AD 2024–0038 refers to its effective date, this AD requires using the effective date of this AD. (3) This AD does not adopt the ‘‘Remarks’’ section of EASA AD 2024–0038. (4) Where EASA AD 2024–0038 does not specify corrective action after a post-repair inspection that has findings of damage, this AD requires obtaining repair instructions before further flight from the FAA, EASA, or Airbus SAS’s EASA Design Organization Approval (DOA), and accomplishing those actions accordingly. Any approval by the DOA must include the DOA-authorized signature. ddrumheller on DSK120RN23PROD with PROPOSALS1 (i) No Reporting Requirement Although material referenced in EASA AD 2024–0038 specifies to submit certain information to the manufacturer, this AD does not include that requirement.

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) 
2022-24-05, which applies to all Airbus SAS Model A318, A319, A320, and 
A321 series airplanes. AD 2022-24-05 requires repetitive inspections of 
certain galleys for corrosion of trolley retainer aluminum blocks and 
delamination of the upper panel of the trolley compartment, and 
applicable corrective action. Since the FAA issued AD 2022-24-05, the 
list of affected galleys has been revised, and a modification has been 
developed to restore the design integrity of the affected galleys. This 
proposed AD would continue to require the actions in AD 2022-24-05, 
provide optional terminating action for the repetitive inspections,

Background

    The FAA issued AD 2022-24-05, Amendment 39-22245 (87 FR 74291, 
December 5, 2022) (AD 2022-24-05), for all Airbus SAS Model A318-111, -
112, -121, and -122 airplanes; Model A319-111, -112, -113, -114, -115, 
-131, -132, -133, -151N, -153N, and -171N airplanes; Model A320-211, -
212, -214, -216, -231, -232, -233, -251N, -252N, -253N, -271N, -272N, 
and -273N airplanes; and Model A321-111, -112, -131, -211, -212, -213, 
-231, -232, -251N, -251NX, -252N, -252NX, -253N, -253NX, -271N, -271NX, 
-272N, and -272NX airplanes. AD 2022-24-05 was prompted by an MCAI 
originated by EASA, which is the Technical Agent for the Member States 
of the European Union. EASA issued AD 2021-0183R1, dated September 20, 
2021, to correct an unsafe condition.
    AD 2022-24-05 requires repetitive inspections of certain galleys 
for corrosion of trolley retainer aluminum blocks and delamination of 
the upper panel of the trolley compartment, and applicable corrective 
actions. The FAA issued AD 2022-24-05 to address damage that could 
affect the galley's capability to hold the trolley under emergency 
landing loads, which could lead to trolley detachment, possibly 
resulting in blocking of an escape path during an emergency exit.

Actions Since AD 2022-24-05 Was Issued

    Since the FAA issued AD 2022-24-05, EASA superseded EASA AD 2021-
0183R1, dated September 20, 2021, and issued EASA AD 2024-0038, dated 
February 5, 2024 (EASA AD 2024-0038) (also referred to as the MCAI), to 
correct an unsafe condition for all Airbus SAS Model A318, A319, A320, 
and A321 series airplanes. EASA AD 2024-0038 states that the list of 
affected galleys has been revised, and Airbus and the galley 
manufacturer have developed a modification to restore the design 
integrity of the affected galleys.
    The FAA is proposing this AD to detect and correct damage that 
could affect the galley's capability to hold the trolley under 
emergency landing loads, which could lead to trolley detachment, 
possibly resulting in blocking of an escape path during an emergency 
exit.
    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-2024-1890.

Explanation of Retained Requirements

    Although this proposed AD does not explicitly restate the 
requirements of AD 2022-24-05, this proposed AD would retain all of the 
requirements of AD 2022-24-05. Those requirements are referenced in 
EASA AD 2024-0038, which, in turn, is referenced in paragraph (g) of 
this proposed AD.

Material Incorporated by Reference Under 1 CFR Part 51

    EASA AD 2024-0038 includes the following provisions:
     Procedures for repetitive general visual inspections of 
certain galleys for discrepancies including corrosion of trolley 
retainer aluminum blocks and delamination of upper panel of trolley 
compartment;
     Corrective actions including repeating the inspection at 
an earlier interval, repairing the trolley compartment upper panel, and 
limiting the trolley weight;
     Procedures for modifying the affected galleys as optional 
terminating action for the repetitive inspections;
     A revised the list of affected galleys; and
     Prohibition of the installation of affected parts unless 
the parts are inspected and corrected.
    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 2024-0038 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 2024-0038 by reference in the FAA 
final rule. This proposed AD would, therefore, require compliance with 
EASA AD 2024-0038 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 2024-0038 does not mean that 
operators need comply only with that section. For example, where the AD 
requirement refers to ``all required

[[Page 58088]]

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 2024-0038. Material required by EASA AD 2024-0038 
for compliance will be available at regulations.gov under Docket No. 
FAA-2024-1890 after the FAA final rule is published.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 1,425 airplanes of U.S. registry. The FAA estimates the 
following costs to comply with this proposed AD:

                                      Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
                                                                                     Cost per      Cost on U.S.
                 Action                          Labor cost           Parts cost      product       operators
----------------------------------------------------------------------------------------------------------------
Retained actions from AD                 2 work-hours x $85 per               $0          $170         $242,250
 2022[dash]24[dash]05.                    hour = $170 per hour.
----------------------------------------------------------------------------------------------------------------


                  Estimated Costs for Optional Actions
------------------------------------------------------------------------
          Labor cost              Parts cost        Cost per product
------------------------------------------------------------------------
Up to 40 work-hours x $85 per             (*)   Up to $3,400.*
 hour = $3,400.
------------------------------------------------------------------------
* The FAA has received no definitive data on which to base the cost
  estimates for the parts associated with the modification specified in
  this proposed AD.

    The FAA estimates the following costs to do any necessary on-
condition actions that would be required based on the results of any 
required actions. The FAA has no way of determining the number of 
aircraft that might need these on-condition actions:

                 Estimated Costs of On-Condition Actions
------------------------------------------------------------------------
              Labor cost                Parts cost     Cost per product
------------------------------------------------------------------------
1 work-hour x $85 per hour = $85.....           $0                  $85
------------------------------------------------------------------------

    The FAA has included all known costs in its cost estimate. 
According to the manufacturer, however, some or all of the costs of 
this proposed AD may be covered under warranty, thereby reducing the 
cost impact on affected operators.

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.

the DOA must include the DOA-authorized signature.

(i) No Reporting Requirement

    Although material referenced in EASA AD 2024-0038 specifies to 
submit certain information to the manufacturer, this AD does not 
include that requirement.

(j) Additional AD Provisions

    The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager, 
International Validation Branch, FAA, has the authority to approve 
AMOCs for this AD, if requested using the procedures found in 14 CFR

    (3) Required for Compliance (RC): Except as required by 
paragraph (j)(2) of this AD, if any material contains procedures or 
tests that are identified as RC, those procedures and tests must be 
done to comply with this AD; any procedures or tests that are not 
identified as RC are recommended. Those procedures and tests that 
are not identified as RC may be deviated from using accepted methods 
in accordance with the operator's maintenance or inspection program 
without obtaining approval of an AMOC, provided the procedures and 
tests identified as RC can be done and the airplane can be put back 
in an airworthy condition. Any substitutions or changes to 
procedures or tests identified as RC require approval of an AMOC.
