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.

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
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.
