ACTION: Final rule. The FAA is superseding Airworthiness Directive (AD) 2018–14– 09, which applied to certain Airbus SAS Model A318 series airplanes; Model A319 series 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 2018–14–09 required repetitive inspections for cracking of the fastener holes in certain fuselage frames, and depending on airplane configuration, provides an optional terminating action to the repetitive inspections. This AD was prompted by reports of early cracking on the four holes of the crossbeam splicing at certain fuselage frames (FR). This AD continues to require the actions in AD 2018–14–09 at modified compliance times, requires further inspections, and provides optional terminating actions for certain airplanes; as specified in European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products. DATES: This AD is effective April 22, 2024. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of April 22, 2024.

SUPPLEMENTARY INFORMATION: Background The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2018–14–09, Amendment 39–19329 (83 FR 34034, July 19, 2018) (AD 2018–14–09). AD 2018–14–09 applied to certain Airbus SAS Model A318 series airplanes; Model A319 series 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 2018–14–09 required repetitive inspections for cracking of the fastener holes in certain fuselage frames, and depending on airplane configuration, provides an optional terminating action to the repetitive inspections. The FAA issued AD 2018–14–09 to address cracking at two upper rows of fasteners of the crossbeam splicing at frame (FR)16 and FR20, on both the left-hand (LH) and right-hand (RH) sides, which can result in reduced structural integrity of the airplane due to the failure of structural components. The NPRM published in the Federal Register on November 6, 2023 (88 FR 76147). The NPRM was prompted by AD 2023–0150, dated July 20, 2023 (EASA AD 2023–0150) (also referred to as the MCAI), issued by EASA, which is the Technical Agent for the Member States of the European Union. The MCAI states that repetitive inspections were instituted due to reports of cracks on the four holes of the crossbeam splicing at FR16 and FR20 on both LH and RH sides. Following further assessments, the need was determined for additional inspections, reduced E:\FR\FM\18MRR1.SGM 18MRR1 19232 Federal Register / Vol. 89, No. 53 / Monday, March 18, 2024 / Rules and Regulations be changed to allow the use of previously issued AMOCs including global AMOC AIR–731–23–00448, dated September 19, 2023, for certain actions of AD 2018–14–09 that are retained in this AD. The FAA agrees and has redesignated paragraph (j)(1) of the proposed AD as paragraphs (j)(1) and (j)(1)(i) of this AD and has added paragraph (j)(1)(ii) of this AD to allow the use of applicable previously issued AMOCs. compliance times, and an additional terminating action option. In the NPRM, the FAA proposed to continue to require repetitive inspections for cracking of the fastener holes in certain fuselage frames, and depending on airplane configuration, to provide an optional terminating action to the repetitive inspections, as specified in EASA AD 2023–0150. The FAA is issuing 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–2023–2144. Conclusion 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 reviewed the relevant data, considered the comments received, and determined that air safety requires adopting this AD as proposed. Accordingly, the FAA is issuing this AD to address the unsafe condition on this product. Except for minor editorial changes, and any other changes described previously, this AD is Discussion of Final Airworthiness Directive Comments The FAA received comments from American Airlines and United Airlines. The following presents the comments received on the NPRM and the FAA’s response. Request To Allow Previously Issued Alternative Methods of Compliance (AMOCs) American Airlines and United Airlines requested that the proposed AD adopted as proposed in the NPRM. None of the changes will increase the economic burden on any operator. Related Service Information Under 1 CFR Part 51 EASA AD 2023–0150 specifies procedures for repetitive rototest inspections for cracking of the holes in certain fuselage frames and crossbeams and applicable corrective actions (including repairing cracking and replacing fasteners); and, for certain airplanes, procedures for modifying the airplane, including cold working instructions in certain fuselage frames and crossbeams, which would terminate the inspections (optional terminating action). 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. Costs of Compliance The FAA estimates that this AD affects 1,680 airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD: ESTIMATED COSTS FOR REQUIRED ACTIONS Action Labor cost Parts cost Retained actions from AD 2018–14–09 ........... 31 work-hours × $85 per hour = $2,635 .......... $0 Cost per product $2,635 Cost on U.S. operators $4,426,800 ESTIMATED COSTS FOR OPTIONAL ACTIONS Labor cost Parts cost Cost per product 28 work-hours × $85 per hour = $2,380 ................................................................................................................. $3,020 $5,400 The FAA estimates the following costs to do any necessary on-condition actions that would be required based on the results of any required or optional actions. The FAA has no way of determining the number of aircraft that might need this on-condition action: ESTIMATED COSTS OF ON-CONDITION REPLACEMENTS Labor cost Parts cost Cost per product 14 work-hours × $85 per hour = $1,190 ................................................................................................................. $50 $1,240 lotter on DSK11XQN23PROD with RULES1 The FAA has received no definitive data on which to base the cost estimates for the on-condition repairs specified in this 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: VerDate Sep<11>2014 16:01 Mar 15, 2024 Jkt 262001 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 PO 00000 Frm 00008 Fmt 4700 Sfmt 4700 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 This AD will not have federalism implications under Executive Order E:\FR\FM\18MRR1.SGM 18MRR1 Federal Register / Vol. 89, No. 53 / Monday, March 18, 2024 / Rules and Regulations 13132. This AD will 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 that this AD: (1) Is not a ‘‘significant regulatory action’’ under Executive Order 12866, (2) Will not affect intrastate aviation in Alaska, and (3) Will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.

Discussion of Final Airworthiness Directive Comments The FAA received a comment from The Air Line Pilots Association, International (ALPA), who supported the NPRM without change. The FAA also received comments from Delta Air Lines. The following presents the comments received on the NPRM and the FAA’s response to each comment. Request for Clarification of Paragraph (i) Referencing Service Information Delta requested clarification of the statement in paragraph (i) of the proposed AD that references laterapproved revisions within the ‘‘Ref. Publications’’ section of EASA AD 2023–0138. Delta requested adding an exception in paragraph (h) of the proposed AD that replaces the language in the EASA AD 2023–0138 section ‘‘Ref. Publications’’ from ‘‘the abovementioned document, or of an ALS revision’’ to ‘‘the above-mentioned document, or of an ALS revision or variation.’’ Delta stated this change would help clarify whether an AMOC (alternative method of compliance) is required to use future variations of Airbus A318/A319/A320/A321 ALS Part 3 Certification Maintenance Requirements (CMR), Revision 08 (Var 8.3 or later). Delta also requested clarification of the statement within the section ‘‘Ref. Publications’’ of EASA AD 2023–0138, referred to in paragraph (i) of the proposed AD, that references laterapproved revisions ‘‘which include the technical content of the variation.’’ Delta wanted to know if a laterapproved variation or revision is acceptable to use if the technical content of the variation is updated in some way, and not exactly the same. The commenter requested this clarification to better understand the allowance provided by the provisions of the ‘‘Ref. Publications’’ section of EASA AD 2023–0138. The FAA disagrees with changing paragraph (h) of this AD. The later version of Airbus A318/A319/A320/ A321 ALS Part 3 Certification Maintenance Requirements (CMR) would be acceptable for compliance as E:\FR\FM\18MRR1.SGM 18MRR1

Airworthiness Directives; Airbus SAS Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2018-14-
09, which applied to certain Airbus SAS Model A318 series airplanes; 
Model A319 series 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 2018-14-09 required repetitive 
inspections for cracking of the fastener holes in certain fuselage 
frames, and depending on airplane configuration, provides an optional 
terminating action to the repetitive inspections. This AD was prompted 
by reports of early cracking on the four holes of the crossbeam 
splicing at certain fuselage frames (FR). This AD continues to require

SUPPLEMENTARY INFORMATION:

Background

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to supersede AD 2018-14-09, Amendment 39-19329 (83 FR 
34034, July 19, 2018) (AD 2018-14-09). AD 2018-14-09 applied to certain 
Airbus SAS Model A318 series airplanes; Model A319 series 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 2018-14-09 required repetitive inspections for cracking of the 
fastener holes in certain fuselage frames, and depending on airplane 
configuration, provides an optional terminating action to the 
repetitive inspections. The FAA issued AD 2018-14-09 to address 
cracking at two upper rows of fasteners of the crossbeam splicing at 
frame (FR)16 and FR20, on both the left-hand (LH) and right-hand (RH) 
sides, which can result in reduced structural integrity of the airplane 
due to the failure of structural components.
    The NPRM published in the Federal Register on November 6, 2023 (88 
FR 76147). The NPRM was prompted by AD 2023-0150, dated July 20, 2023 
(EASA AD 2023-0150) (also referred to as the MCAI), issued by EASA, 
which is the Technical Agent for the Member States of the European 
Union. The MCAI states that repetitive inspections were instituted due 
to reports of cracks on the four holes of the crossbeam splicing at 
FR16 and FR20 on both LH and RH sides. Following further assessments, 
the need was determined for additional inspections, reduced

[[Page 19232]]

compliance times, and an additional terminating action option.
    In the NPRM, the FAA proposed to continue to require repetitive 
inspections for cracking of the fastener holes in certain fuselage 
frames, and depending on airplane configuration, to provide an optional 
terminating action to the repetitive inspections, as specified in EASA 
AD 2023-0150. The FAA is issuing 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-2023-2144.

Discussion of Final Airworthiness Directive

Comments

    The FAA received comments from American Airlines and United 
Airlines. The following presents the comments received on the NPRM and 
the FAA's response.

Request To Allow Previously Issued Alternative Methods of Compliance 
(AMOCs)

    American Airlines and United Airlines requested that the proposed 
AD be changed to allow the use of previously issued AMOCs including 
global AMOC AIR-731-23-00448, dated September 19, 2023, for certain 
actions of AD 2018-14-09 that are retained in this AD.
    The FAA agrees and has redesignated paragraph (j)(1) of the 
proposed AD as paragraphs (j)(1) and (j)(1)(i) of this AD and has added 
paragraph (j)(1)(ii) of this AD to allow the use of applicable 
previously issued AMOCs.

Conclusion

    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 reviewed the relevant data, considered the 
comments received, and determined that air safety requires adopting 
this AD as proposed. Accordingly, the FAA is issuing this AD to address 
the unsafe condition on this product. Except for minor editorial 
changes, and any other changes described previously, this AD is adopted 
as proposed in the NPRM. None of the changes will increase the economic 
burden on any operator.

Related Service Information Under 1 CFR Part 51

    EASA AD 2023-0150 specifies procedures for repetitive rototest 
inspections for cracking of the holes in certain fuselage frames and 
crossbeams and applicable corrective actions (including repairing 
cracking and replacing fasteners); and, for certain airplanes, 
procedures for modifying the airplane, including cold working 
instructions in certain fuselage frames and crossbeams, which would 
terminate the inspections (optional terminating action). 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.

Costs of Compliance

    The FAA estimates that this AD affects 1,680 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this AD:

                                      Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
                                                                                     Cost per      Cost on U.S.

28 work-hours x $85 per hour = $2,380.          $3,020           $5,400
------------------------------------------------------------------------

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

------------------------------------------------------------------------
14 work-hours x $85 per hour = $1,190.             $50           $1,240
------------------------------------------------------------------------

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

    This AD will not have federalism implications under Executive Order

[[Page 19233]]

13132. This AD will 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 that this AD:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Will not affect intrastate aviation in Alaska, and
    (3) Will not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.
