Airworthiness Directives; Leonardo S.p.a. Helicopters

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
certain Leonardo S.p.a Model AW189 helicopters. This AD was prompted by 
a report of an incorrect connection of the inflation hoses to the tee 
manifolds of the inflation line on the emergency flotation system (EFS) 
assembly. This AD requires visually inspecting the yellow sleeves and 
hoses installed on each EFS assembly and depending on the inspection 
results, accomplishing the corrective actions in the applicable service 
information as specified in a European Aviation Safety Agency (now 
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 November 22, 2021.
    The Director of the Federal Register approved the incorporation by 
reference of a certain document listed in this AD as of November 22, 
2021.

SUPPLEMENTARY INFORMATION:

Background

    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2018-0279, dated December 14, 2018 
(EASA AD 2018-0279), to correct an unsafe condition for Leonardo S.p.a. 
(formerly Finmeccanica Helicopter Division, AgustaWestland) 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 
July 15, 2021 (86 FR 37258). The NPRM was prompted by a report of a 
discrepancy found during a maintenance inspection related to the 
connection of the inflation hoses to the helicopter tee manifolds. EASA 
AD 2018-0279 states the yellow sleeve on the right-hand (RH) aft EFS 
assembly was installed on the straight-to-straight hose instead of the 
straight-to-45 degree hose, which caused the two hoses to be 
incorrectly connected to the tee manifolds at the inflation line. The

[[Page 57580]]

NPRM proposed to require accomplishing the actions specified in EASA AD 
2018-0279, described previously, as incorporated by reference, except 
for any differences identified as exceptions in the regulatory text of 
this proposed AD and except as discussed under ``Differences Between 
this Proposed AD and EASA AD 2018-0279.''
    The FAA is issuing this AD to prevent partial inflation of the 
flotation bags which could prevent a timely egress from the helicopter 
and consequent injury to helicopter occupants. See EASA AD 2018-0279 
for additional background information.

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 2018-0279 requires a visual inspection of each affected EFS 
assembly for correct installation of the yellow sleeves and proper 
connection of the inflation hoses to the float assembly and the bottle 
assembly. Depending on these inspection results, if an incorrect 
installation of the yellow sleeve or an incorrect connection of the 
inflation hoses is detected, EASA AD 2018-0279 requires, before next 
flight, removing incorrectly installed yellow sleeves, and incorrectly 
installed hoses, restoring markings on re-installed yellow sleeves, and 
re-connecting or re-installing hoses in accordance with the applicable 
service information. EASA AD 2018-0279 also prohibits installing any 
affected EFS assembly on any helicopter.
    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.

Differences Between This AD and EASA AD 2018-0279

    EASA AD 2018-0279 applies to Model AW189 helicopters, all serial 
numbers (S/Ns), whereas this AD only applies to Model AW189 helicopters 
with EFS assemblies having certain part-numbered aft assemblies with 
certain S/Ns installed.

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.
    Visually inspecting each EFS assembly takes about 0.75 work-hours 
for an estimated cost of $64 per inspection and $260 for the U.S. 
fleet.
    Performing the corrective actions on each EFS assembly takes about 
1.25 work-hours for an estimated cost of $113 per EFS assembly.

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 helicopters 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.
