Any commentary that the FAA receives which is not specifically designated as CBI will be placed in the public docket for this rulemaking. Background The FAA issued AD 2022–08–08, Amendment 39–22011 (87 FR 23755, April 21, 2022) (AD 2022–08–08), for certain Airbus SAS Model A318 series airplanes; Model A319–111, –112, –113, –114, –115, –131, –132, and –133 airplanes; Model A320–211, –212, –214, –216, –231, –232, and –233 airplanes; and Model A321–111, –112, –131, –211, –212, –213, –231, and –232 airplanes. AD 2022–08–08 requires repetitive special detailed inspections of certain areas and applicable on-condition actions. The FAA issued AD 2022–08– 08 to address cracks in the double joggle areas at frame (FR) 16 and FR20, righthand and left-hand sides, which, if not detected and corrected, could reduce the structural integrity of the fuselage. The FAA issued an NPRM to amend 14 CFR part 39 by adding an AD to supersede AD 2022–08–08 that would apply to certain Airbus SAS Model E:\FR\FM\18FEP1.SGM 18FEP1 9696 Federal Register / Vol. 90, No. 31 / Tuesday, February 18, 2025 / Proposed Rules airworthiness limitation items (ALIs), cracks were detected in the double joggle areas at frame (FR) 16 and FR20 in the nose forward fuselage. The unsafe condition, if not addressed, could result in reduced structural integrity of the fuselage. You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA–2024–1895. A318 series airplanes; Model A319–111, –112, –113, –114, –115, –131, –132, and –133 airplanes; Model A320–211, –212, –214, –216, –231, –232, and –233 airplanes; and Model A321–111, –112, –131, –211, –212, –213, –231, and –232 airplanes. The NPRM published in the Federal Register on July 24, 2024 (89 FR 59857). The NPRM was prompted by an MCAI issued by The European Union Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union. EASA issued AD 2023–0212, dated December 6, 2023 (EASA 2023–0212), to correct an unsafe condition. The NPRM proposed to continue to require repetitive special detailed inspections for cracking of double joggle areas at FR16 and FR20, right-hand and left-hand sides, and applicable on-condition actions (repair). The NPRM also proposed to provide an optional modification of the double joggle area that would terminate the repetitive inspections, and add airplanes to the applicability. Comments The FAA received a comment from Air Line Pilots Association, International (ALPA), who supported the NPRM without change. The FAA received an additional comment from American Airlines. The following presents the FAA’s response. lotter on DSK11XQN23PROD with PROPOSALS1 Actions Since the NPRM Was Issued Since the FAA issued the NPRM, EASA superseded AD 2023–0212 and issued EASA AD 2024–0217, dated November 18, 2024 (EASA AD 2024– 0217) (also referred to as the MCAI). The MCAI states that EASA AD 2023–0212 incorrectly terminated the AD-mandated repetitive inspections for all the Airbus repair instructions; only those in which the termination of the AD mandated inspection was explicitly written in the Airbus approved instructions should have been terminated. Therefore, additional requirements are necessary for airplanes that have been repaired after accomplishment of ALI tasks 531153–02 or 531155–02. The MCAI applies to certain Airbus SAS Model A318–111, –112, –121, –122 airplanes; Model 319–111, –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. The FAA is proposing this AD to address reports that, during inspections accomplished as specified in certain Request To Require New EASA AD In the proposed AD, the FAA would have required compliance with EASA AD 2023–0212 (with specified exceptions). American Airlines stated that EASA issued proposed AD (PAD) 24–085 to supersede EASA AD 2023– 0212. American Airlines requested that the FAA amend the proposed AD to require compliance with the new EASA AD to ensure that operators and the FAA are aligned with the latest EASA requirements. The FAA agrees with American Airlines’ request. This SNPRM would require the actions specified in EASA AD 2024–0217 including the additional requirements previously described relating to the terminating action for the repetitive inspections. Additional Changes Made to This Proposed AD Because the NPRM incorrectly allowed for termination of the mandated inspections for all Airbus repair instructions, this proposed AD revises the NPRM by requiring the actions specified in EASA AD 2024–0217, which in turn corrects the terminating action provisions. Material Incorporated by Reference Under 1 CFR Part 51 The FAA reviewed EASA AD 2024– 0217. This material specifies procedures for repetitive special detailed inspections for cracking of double joggle areas at FR16 and FR20, right-hand and left-hand sides, applicable on-condition actions (repair), and an optional modification of the double joggle area that terminates the repetitive inspections. The modification includes a rotating probe inspection of certain fastener holes for cracks, a check of the fastener holes for a minimum diameter, and applicable on-condition actions. EASA AD 2024–0217 also specifies that new SRM tasks have been developed that are acceptable for compliance with the corrective actions required by AD 2022–08–08 for airplanes affected by that AD. EASA AD 2024–0217 specifies additional requirements for airplanes that have been repaired after accomplishment of airworthiness limitations item (ALI) task 531153–02 or 531155–02. 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 and material referenced above. The FAA is issuing this SNPRM after determining that the unsafe condition described previously is likely to exist or develop on other products of the same type design. Certain changes described above expand the scope of the NPRM. As a result, it is necessary to reopen the comment period to provide additional opportunity for the public to comment on this SNPRM. Proposed Requirements of This SNPRM This proposed AD would retain all requirements of AD 2022–08–08. This proposed AD would add requirements for certain airplanes, add airplanes to the applicability, and require accomplishing the actions specified in the material described previously. Costs of Compliance The FAA estimates that this AD, if adopted as proposed, would affect 1,755 airplanes of U.S. registry. The FAA estimates the following costs to comply with this proposed AD: ESTIMATED COSTS FOR REQUIRED ACTIONS Labor cost Parts cost Up to 55 work-hours × $85 per hour = Up to $4,675 ................. VerDate Sep<11>2014 16:47 Feb 14, 2025 Jkt 265001 PO 00000 Frm 00002 $0 Fmt 4702 Cost per product Cost on U.S. operators Up to $4,675 ............................ Sfmt 4702 E:\FR\FM\18FEP1.SGM 18FEP1 Up to $8,204,625. Federal Register / Vol. 90, No. 31 / Tuesday, February 18, 2025 / Proposed Rules 9697 ESTIMATED COSTS FOR OPTIONAL ACTIONS Labor cost Parts cost Cost per product 60 work-hours × $85 per hour = $5,100 ............................................................................................................. $1,624 $6,724 The FAA has received no definitive data on which to base the cost estimates for the on-condition repairs specified in this proposed AD. 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 lotter on DSK11XQN23PROD with PROPOSALS1 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: Supplemental notice of proposed rulemaking (SNPRM).

-----------------------------------------------------------------------

SUMMARY: The FAA is revising a notice of proposed rulemaking (NPRM) to 
supersede Airworthiness Directive (AD) 2022-08-08, which applies to 
certain Airbus SAS Model A318-111, -112, -121, -122 airplanes; Model 
319-111, -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. This 
action revises the NPRM by adding requirements for certain airplanes. 
The FAA is proposing this AD to address the unsafe condition on these 
products. Since these actions would impose an additional burden over 
that in the NPRM, the FAA is reopening the comment period to allow the 
public the chance to comment on these changes.

Background

    The FAA issued AD 2022-08-08, Amendment 39-22011 (87 FR 23755, 
April 21, 2022) (AD 2022-08-08), for certain Airbus SAS Model A318 
series airplanes; Model A319-111, -112, -113, -114, -115, -131, -132, 
and -133 airplanes; Model A320-211, -212, -214, -216, -231, -232, and -
233 airplanes; and Model A321-111, -112, -131, -211, -212, -213, -231, 
and -232 airplanes. AD 2022-08-08 requires repetitive special detailed 
inspections of certain areas and applicable on-condition actions. The 
FAA issued AD 2022-08-08 to address cracks in the double joggle areas 
at frame (FR) 16 and FR20, right-hand and left-hand sides, which, if 
not detected and corrected, could reduce the structural integrity of 
the fuselage.
    The FAA issued an NPRM to amend 14 CFR part 39 by adding an AD to 
supersede AD 2022-08-08 that would apply to certain Airbus SAS Model

[[Page 9696]]

A318 series airplanes; Model A319-111, -112, -113, -114, -115, -131, -
132, and -133 airplanes; Model A320-211, -212, -214, -216, -231, -232, 
and -233 airplanes; and Model A321-111, -112, -131, -211, -212, -213, -
231, and -232 airplanes. The NPRM published in the Federal Register on 
July 24, 2024 (89 FR 59857). The NPRM was prompted by an MCAI issued by 
The European Union Aviation Safety Agency (EASA), which is the 
Technical Agent for the Member States of the European Union. EASA 
issued AD 2023-0212, dated December 6, 2023 (EASA 2023-0212), to 
correct an unsafe condition. The NPRM proposed to continue to require 
repetitive special detailed inspections for cracking of double joggle 
areas at FR16 and FR20, right-hand and left-hand sides, and applicable 
on-condition actions (repair). The NPRM also proposed to provide an 
optional modification of the double joggle area that would terminate 
the repetitive inspections, and add airplanes to the applicability.

Actions Since the NPRM Was Issued

    Since the FAA issued the NPRM, EASA superseded AD 2023-0212 and 
issued EASA AD 2024-0217, dated November 18, 2024 (EASA AD 2024-0217) 
(also referred to as the MCAI). The MCAI states that EASA AD 2023-0212 
incorrectly terminated the AD-mandated repetitive inspections for all 
the Airbus repair instructions; only those in which the termination of 
the AD mandated inspection was explicitly written in the Airbus 
approved instructions should have been terminated. Therefore, 
additional requirements are necessary for airplanes that have been 
repaired after accomplishment of ALI tasks 531153-02 or 531155-02. The 
MCAI applies to certain Airbus SAS Model A318-111, -112, -121, -122 
airplanes; Model 319-111, -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.
    The FAA is proposing this AD to address reports that, during 
inspections accomplished as specified in certain airworthiness 
limitation items (ALIs), cracks were detected in the double joggle 
areas at frame (FR) 16 and FR20 in the nose forward fuselage. The 
unsafe condition, if not addressed, could result in reduced structural 
integrity of the fuselage. You may examine the MCAI in the AD docket at 
regulations.gov under Docket No. FAA-2024-1895.

Comments

    The FAA received a comment from Air Line Pilots Association, 
International (ALPA), who supported the NPRM without change.
    The FAA received an additional comment from American Airlines. The 
following presents the FAA's response.

Request To Require New EASA AD

    In the proposed AD, the FAA would have required compliance with 
EASA AD 2023-0212 (with specified exceptions). American Airlines stated 
that EASA issued proposed AD (PAD) 24-085 to supersede EASA AD 2023-
0212. American Airlines requested that the FAA amend the proposed AD to 
require compliance with the new EASA AD to ensure that operators and 
the FAA are aligned with the latest EASA requirements.
    The FAA agrees with American Airlines' request. This SNPRM would 
require the actions specified in EASA AD 2024-0217 including the 
additional requirements previously described relating to the 
terminating action for the repetitive inspections.

Additional Changes Made to This Proposed AD

    Because the NPRM incorrectly allowed for termination of the 
mandated inspections for all Airbus repair instructions, this proposed 
AD revises the NPRM by requiring the actions specified in EASA AD 2024-
0217, which in turn corrects the terminating action provisions.

Material Incorporated by Reference Under 1 CFR Part 51

    The FAA reviewed EASA AD 2024-0217. This material specifies 
procedures for repetitive special detailed inspections for cracking of 
double joggle areas at FR16 and FR20, right-hand and left-hand sides, 
applicable on-condition actions (repair), and an optional modification 
of the double joggle area that terminates the repetitive inspections. 
The modification includes a rotating probe inspection of certain 
fastener holes for cracks, a check of the fastener holes for a minimum 
diameter, and applicable on-condition actions. EASA AD 2024-0217 also 
specifies that new SRM tasks have been developed that are acceptable 
for compliance with the corrective actions required by AD 2022-08-08 
for airplanes affected by that AD. EASA AD 2024-0217 specifies 
additional requirements for airplanes that have been repaired after 
accomplishment of airworthiness limitations item (ALI) task 531153-02 
or 531155-02. 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 and 
material referenced above. The FAA is issuing this SNPRM after 
determining that the unsafe condition described previously is likely to 
exist or develop on other products of the same type design.
    Certain changes described above expand the scope of the NPRM. As a 
result, it is necessary to reopen the comment period to provide 
additional opportunity for the public to comment on this SNPRM.

Proposed Requirements of This SNPRM

    This proposed AD would retain all requirements of AD 2022-08-08. 
This proposed AD would add requirements for certain airplanes, add 
airplanes to the applicability, and require accomplishing the actions 
specified in the material described previously.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 1,755 airplanes of U.S. registry. The FAA estimates the 
following costs to comply with this proposed AD:

                                      Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
                Labor cost                  Parts cost        Cost per product          Cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
Up to 55 work-hours x $85 per hour = Up             $0  Up to $4,675...............  Up to $8,204,625.
 to $4,675.
----------------------------------------------------------------------------------------------------------------


[[Page 9697]]


                  Estimated Costs for Optional Actions
------------------------------------------------------------------------
              Labor cost                Parts cost     Cost per product
------------------------------------------------------------------------
60 work-hours x $85 per hour = $5,100       $1,624               $6,724
------------------------------------------------------------------------

    The FAA has received no definitive data on which to base the cost 
estimates for the on-condition repairs specified in this proposed AD.

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
