SUPPLEMENTARY INFORMATION: Background EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2022–0214, dated October 21, 2022 (EASA AD 2022–0214), to correct an unsafe condition on certain serial-numbered Leonardo S.p.A. Model AW189 helicopters. The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain Leonardo S.p.a. Model AW189 helicopters. The NPRM published in the Federal Register on February 27, 2024 (89 FR 14420). The NPRM was prompted by a report of an uncommanded deployment of the ELS. Subsequent investigation determined incorrect installation of its control cable could have caused the occurrence. The NPRM proposed to require a one-time inspection of the life-raft installations and, depending on the results, PO 00000 Frm 00001 Fmt 4700 Sfmt 4700 accomplishing additional actions, as specified in EASA AD 2022–0214. The FAA is issuing this AD to address unintended activation and deployment of the ELS. The unsafe condition, if not addressed, could result in unintended activation and deployment of the ELS in flight with possible impact on the rotors, resulting in reduced control of the helicopter. 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 2022–0214 requires a onetime inspection of both the left- and right-side life-raft installations for certain serial-numbered helicopters and, depending on findings, replacing its control cable and checking the assembly, replacing a cable pulley cover, correcting the cable installation, and replacing the life-raft assembly, as applicable. 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. Other Related Service Information The FAA also reviewed Leonardo Helicopters Alert Service Bulletin No.189–315, dated October 20, 2022. This service information specifies procedures for inspecting the ELS. Differences Between This AD and the EASA AD The service information referenced in EASA AD 2022–0214 specifies taking pictures, completing an inspection report, and sending removed parts to the E:\FR\FM\17JNR1.SGM 17JNR1 51204 Federal Register / Vol. 89, No. 117 / Monday, June 17, 2024 / Rules and Regulations khammond on DSKJM1Z7X2PROD with RULES manufacturer, whereas this AD does not include those actions. The service information referenced in EASA AD 2022–0214 cautions that step 3.3 shall be performed by trained operators or by authorized service stations only, whereas this AD requires that step to be accomplished by persons authorized under 14 CFR 43.3. EASA AD 2022–0214 refers to the emergency life-raft assembly inspection as a ‘‘check,’’ whereas this AD refers to that action as an ‘‘inspection’’ because that action must be accomplished by persons authorized under 14 CFR 43.3. EASA AD 2022–0214 allows installing inoperative placard(s) in clear view of both pilots to defer certain corrective action, provided all flight crews are informed and, thereafter, the helicopter is operated accordingly. FAA regulations mandate compliance with placards. However, this AD does not require informing flight crews or operating the helicopter accordingly because compliance with such requirements in an AD is impracticable to demonstrate or track on an ongoing basis; therefore, a requirement to operate the aircraft in such a manner is unenforceable. Nonetheless, flight crews of the helicopters identified in the applicability must operate in accordance with the placard(s) in this AD. Costs of Compliance The FAA estimates that this AD affects 4 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. Inspecting the left- and right-hand side life-raft installations will take approximately 4 work-hours for an estimated cost of $340 per helicopter and $1,360 for the U.S. fleet. If required, replacing a control cable and inspecting the life-raft assembly will take approximately 1 work-hour and parts cost approximately $1,665 for an estimated cost of $1,750 per side. If required, replacing a pulley cover will take approximately 0.5 work-hour and parts cost approximately $100 for an estimated cost of $143 per side. If required, correcting the cable installation will take approximately 4 work-hours and cost approximately $340 per side. If required, replacing a life raft assembly will take approximately 4 work-hours and parts cost approximately $125,700 for an estimated cost of $126,040 per side. The FAA has included all known costs in its cost estimate. According to the manufacturer, however, some of the costs of this AD may be covered under VerDate Sep<11>2014 16:18 Jun 14, 2024 Jkt 262001 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 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. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. The Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: PART 39—AIRWORTHINESS DIRECTIVES 1.

SUPPLEMENTARY INFORMATION:

Background

    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2022-0214, dated October 21, 2022 
(EASA AD 2022-0214), to correct an unsafe condition on certain serial-
numbered Leonardo S.p.A. Model AW189 helicopters.
    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 by adding an AD that would apply to certain Leonardo S.p.a. 
Model AW189 helicopters. The NPRM published in the Federal Register on 
February 27, 2024 (89 FR 14420). The NPRM was prompted by a report of 
an uncommanded deployment of the ELS. Subsequent investigation 
determined incorrect installation of its control cable could have 
caused the occurrence. The NPRM proposed to require a one-time 
inspection of the life-raft installations and, depending on the 
results, accomplishing additional actions, as specified in EASA AD 
2022-0214.
    The FAA is issuing this AD to address unintended activation and 
deployment of the ELS. The unsafe condition, if not addressed, could 
result in unintended activation and deployment of the ELS in flight 
with possible impact on the rotors, resulting in reduced control of the 
helicopter.

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 2022-0214 requires a one-time inspection of both the left- 
and right-side life-raft installations for certain serial-numbered 
helicopters and, depending on findings, replacing its control cable and 
checking the assembly, replacing a cable pulley cover, correcting the 
cable installation, and replacing the life-raft assembly, as 
applicable.
    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.

Other Related Service Information

    The FAA also reviewed Leonardo Helicopters Alert Service Bulletin 
No.189-315, dated October 20, 2022. This service information specifies 
procedures for inspecting the ELS.

Differences Between This AD and the EASA AD

    The service information referenced in EASA AD 2022-0214 specifies 
taking pictures, completing an inspection report, and sending removed 
parts to the

[[Page 51204]]

manufacturer, whereas this AD does not include those actions.
    The service information referenced in EASA AD 2022-0214 cautions 
that step 3.3 shall be performed by trained operators or by authorized 
service stations only, whereas this AD requires that step to be 
accomplished by persons authorized under 14 CFR 43.3.
    EASA AD 2022-0214 refers to the emergency life-raft assembly 
inspection as a ``check,'' whereas this AD refers to that action as an 
``inspection'' because that action must be accomplished by persons 
authorized under 14 CFR 43.3.
    EASA AD 2022-0214 allows installing inoperative placard(s) in clear 
view of both pilots to defer certain corrective action, provided all 
flight crews are informed and, thereafter, the helicopter is operated 
accordingly. FAA regulations mandate compliance with placards. However, 
this AD does not require informing flight crews or operating the 
helicopter accordingly because compliance with such requirements in an 
AD is impracticable to demonstrate or track on an ongoing basis; 
therefore, a requirement to operate the aircraft in such a manner is 
unenforceable. Nonetheless, flight crews of the helicopters identified 
in the applicability must operate in accordance with the placard(s) in 
this AD.

Costs of Compliance

    The FAA estimates that this AD affects 4 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.
    Inspecting the left- and right-hand side life-raft installations 
will take approximately 4 work-hours for an estimated cost of $340 per 
helicopter and $1,360 for the U.S. fleet.
    If required, replacing a control cable and inspecting the life-raft 
assembly will take approximately 1 work-hour and parts cost 
approximately $1,665 for an estimated cost of $1,750 per side. If 
required, replacing a pulley cover will take approximately 0.5 work-
hour and parts cost approximately $100 for an estimated cost of $143 
per side. If required, correcting the cable installation will take 
approximately 4 work-hours and cost approximately $340 per side. If 
required, replacing a life raft assembly will take approximately 4 
work-hours and parts cost approximately $125,700 for an estimated cost 
of $126,040 per side.
    The FAA has included all known costs in its cost estimate. 
According to the manufacturer, however, some of the costs of this 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

    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.

The Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA amends 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

    Authority: 49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive:

2024-10-02 Leonardo S.p.a.: Amendment 39-22747; Docket No. FAA-2024-
0235; Project Identifier MCAI-2022-01376-R.

(a) Effective Date

    This airworthiness directive (AD) is effective July 22, 2024.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Leonardo S.p.a. Model AW189 helicopters, 
certificated in any category, as identified in European Union 
Aviation Safety Agency (EASA) AD 2022-0214, dated October 21, 2022 
(EASA AD 2022-0214).

(d) Subject

    Joint Aircraft Service Component (JASC) Code 2564, Life Raft.

(e) Unsafe Condition

    This AD was prompted by a report of an uncommanded deployment of 
the Emergency life-raft system (ELS), possibly due to an incorrect 
installation of its control cable. The FAA is issuing this AD to 
address unintended activation and deployment of the ELS. The unsafe 
condition, if not addressed, could result in unintended activation 
and deployment of the ELS in flight with possible impact on the 
rotors, resulting in reduced control of the helicopter.

(f) Compliance

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

(g) Requirements

    Except as specified in paragraphs (h) and (i) of this AD: Comply 
with all required actions and compliance times specified in, and in 
accordance with, EASA AD 2022-0214.

(h) Exceptions to EASA AD 2022-0214

    (1) Where EASA AD 2022-0214 refers to ``flight hours,'' this AD
