SUPPLEMENTARY INFORMATION: Background EASA, which is the Technical Agent for the Member States of the European Union, has issued a series of ADs with the most recent being EASA AD 2023– 0160, dated August 16, 2023 (EASA AD 2023–0160), to correct an unsafe condition for Leonardo S.p.A. Model AW169 helicopters. The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to all Leonardo S.p.a. Model AW169 helicopters. The NPRM published in the Federal Register on December 21, 2023 (88 FR 88274). The NPRM was prompted by a determination that new or more restrictive airworthiness limitations are necessary. The NPRM proposed to require accomplishing the actions specified in EASA AD 2023–0160, as incorporated by reference, except for any differences identified as exceptions in the regulatory text of this AD and except as discussed under ‘‘Differences Between this AD and the EASA AD.’’ The FAA is issuing this AD to address the unsafe condition on these products. You may examine the EASA AD in the AD docket at regulations.gov under Docket No. FAA–2023–2244. Discussion of Final Airworthiness Directive Comments The FAA received no comments on the NPRM or on the determination of the costs. PO 00000 Frm 00002 Fmt 4700 Sfmt 4700 Conclusion These helicopters have been approved by EASA and are approved for operation in the United States. Pursuant to the FAA’s bilateral agreement with the European Union, EASA has notified the FAA about the unsafe condition described in its AD. The FAA reviewed the relevant data and determined that air safety requires adopting this AD as proposed. Accordingly, the FAA is issuing this AD to address the unsafe condition on these helicopters. Related Service Information Under 1 CFR Part 51 EASA AD 2023–0160 requires replacing components before exceeding their life limits and accomplishing maintenance tasks within thresholds and intervals specified in the applicable ALS as defined in EASA AD 2023–0160. Depending on the results of the maintenance tasks, EASA AD 2023– 0160 requires accomplishing corrective action(s) or contacting Leonardo [Leonardo S.p.a.] for approved instructions and accomplishing those instructions. EASA AD 2023–0160 also requires revising the Aircraft Maintenance Programme (AMP) by incorporating the limitations, tasks, and associated thresholds and intervals described in the specified ALS as applicable to the helicopter model and configuration. Revising the AMP constitutes terminating action for the requirement to record accomplishment of the actions of replacing components before exceeding their life limits and accomplishing maintenance tasks within the thresholds and intervals specified in the applicable ALS as required by EASA AD 2023–0160 for demonstration of AD compliance on a continued basis. 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 section. Other Related Service Information The FAA also reviewed AW169 Air vehicle maintenance planning information, 69–A–AMPI–00–P, Chapter 04, ALS, Issue 21, dated July 7, 2023. This service information specifies airworthiness limitations, tasks, and associated thresholds and intervals for various parts, and specifies new or more restrictive airworthiness limitations for certain components installed on the tail rotor system. Differences Between This AD and the EASA AD EASA AD 2023–0160 requires replacing certain components before E:\FR\FM\09APR1.SGM 09APR1 ddrumheller on DSK120RN23PROD with RULES1 Federal Register / Vol. 89, No. 69 / Tuesday, April 9, 2024 / Rules and Regulations exceeding applicable life limits, accomplishing certain maintenance tasks within thresholds and intervals as specified in the ALS, as defined within, and depending on the results, accomplishing corrective action within the compliance time specified in that ALS. EASA AD 2023–0160 also requires revising the approved AMP to incorporate the limitations, tasks, and associated thresholds and intervals described in that ALS within 12 months after its effective date. Whereas, this AD requires revising existing documents and programs within 30 days to incorporate the limitations, tasks, and associated thresholds and intervals described in that ALS, and clarifies that if an incorporated limitation or threshold therein is reached before 30 days after the effective date of this final rule, you still have up to 30 days after the effective date of this final rule to accomplish the corresponding task. 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. Costs of Compliance The FAA estimates that this AD affects 10 helicopters of U.S. Registry. Labor rates are estimated at $85 per work-hour. Based on these numbers, the FAA estimates the following costs to comply with this AD. Revising the ALS of the existing helicopter maintenance manual or ICA for your helicopter and the existing approved maintenance or inspection program for your helicopter, as applicable, will take 2 work-hours for an estimated cost of $170 per helicopter and $1,700 for the U.S. fleet. The Amendment 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.

SUPPLEMENTARY INFORMATION:

Background

    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued a series of ADs with the most recent being 
EASA AD 2023-0160, dated August 16, 2023 (EASA AD 2023-0160), to 
correct an unsafe condition for Leonardo S.p.A. Model AW169 
helicopters.
    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 by adding an AD that would apply to all Leonardo S.p.a. 
Model AW169 helicopters. The NPRM published in the Federal Register on 
December 21, 2023 (88 FR 88274). The NPRM was prompted by a 
determination that new or more restrictive airworthiness limitations 
are necessary. The NPRM proposed to require accomplishing the actions 
specified in EASA AD 2023-0160, as incorporated by reference, except 
for any differences identified as exceptions in the regulatory text of 
this AD and except as discussed under ``Differences Between this AD and 
the EASA AD.'' The FAA is issuing this AD to address the unsafe 
condition on these products.
    You may examine the EASA AD in the AD docket at regulations.gov 
under Docket No. FAA-2023-2244.

Discussion of Final Airworthiness Directive

Comments

    The FAA received no comments on the NPRM or on the determination of 
the costs.

Conclusion

    These helicopters have been approved by EASA and are approved for 
operation in the United States. Pursuant to the FAA's bilateral 
agreement with the European Union, EASA has notified the FAA about the 
unsafe condition described in its AD. The FAA reviewed the relevant 
data and determined that air safety requires adopting this AD as 
proposed. Accordingly, the FAA is issuing this AD to address the unsafe 
condition on these helicopters.

Related Service Information Under 1 CFR Part 51

    EASA AD 2023-0160 requires replacing components before exceeding 
their life limits and accomplishing maintenance tasks within thresholds 
and intervals specified in the applicable ALS as defined in EASA AD 
2023-0160. Depending on the results of the maintenance tasks, EASA AD 
2023-0160 requires accomplishing corrective action(s) or contacting 
Leonardo [Leonardo S.p.a.] for approved instructions and accomplishing 
those instructions. EASA AD 2023-0160 also requires revising the 
Aircraft Maintenance Programme (AMP) by incorporating the limitations, 
tasks, and associated thresholds and intervals described in the 
specified ALS as applicable to the helicopter model and configuration. 
Revising the AMP constitutes terminating action for the requirement to 
record accomplishment of the actions of replacing components before 
exceeding their life limits and accomplishing maintenance tasks within 
the thresholds and intervals specified in the applicable ALS as 
required by EASA AD 2023-0160 for demonstration of AD compliance on a 
continued basis.
    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 section.

Other Related Service Information

    The FAA also reviewed AW169 Air vehicle maintenance planning 
information, 69-A-AMPI-00-P, Chapter 04, ALS, Issue 21, dated July 7, 
2023. This service information specifies airworthiness limitations, 
tasks, and associated thresholds and intervals for various parts, and 
specifies new or more restrictive airworthiness limitations for certain 
components installed on the tail rotor system.

Differences Between This AD and the EASA AD

    EASA AD 2023-0160 requires replacing certain components before

[[Page 24683]]

exceeding applicable life limits, accomplishing certain maintenance 
tasks within thresholds and intervals as specified in the ALS, as 
defined within, and depending on the results, accomplishing corrective 
action within the compliance time specified in that ALS. EASA AD 2023-
0160 also requires revising the approved AMP to incorporate the 
limitations, tasks, and associated thresholds and intervals described 
in that ALS within 12 months after its effective date. Whereas, this AD 
requires revising existing documents and programs within 30 days to 
incorporate the limitations, tasks, and associated thresholds and 
intervals described in that ALS, and clarifies that if an incorporated 
limitation or threshold therein is reached before 30 days after the 
effective date of this final rule, you still have up to 30 days after 
the effective date of this final rule to accomplish the corresponding 
task.

Costs of Compliance

    The FAA estimates that this AD affects 10 helicopters of U.S. 
Registry. Labor rates are estimated at $85 per work-hour. Based on 
these numbers, the FAA estimates the following costs to comply with 
this AD.
    Revising the ALS of the existing helicopter maintenance manual or 
ICA for your helicopter and the existing approved maintenance or 
inspection program for your helicopter, as applicable, will take 2 
work-hours for an estimated cost of $170 per helicopter and $1,700 for 
the U.S. fleet.

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 
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.

system.

(e) Unsafe Condition

    This AD was prompted by a determination that new or more 
restrictive airworthiness limitations are necessary. The FAA is 
issuing this AD to address fatigue cracking, damage, and corrosion 
in principle structural elements. The unsafe condition, if not 
addressed, could result in failure of a part and loss of control of 
the helicopter.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Required Actions

    Except as specified in paragraphs (h) and (i) of this AD: Comply

after the effective date of this AD, revise the airworthiness 
limitations section of your existing helicopter maintenance manual 
or instructions for continued airworthiness and your existing 
approved maintenance or inspection program, as applicable.''
    (4) The initial compliance time for doing the tasks specified in 
paragraph (3) of EASA AD 2023-0160 is on or before the applicable
