    The FAA must receive comments on this airworthiness directive (AD)  by
    August 30, 2021.

(b) AFFECTED ADS

    None.

(c) APPLICABILITY

    This  AD   applies  to   Leonardo  S.p.a.   Model  AW189  helicopters,
    certificated in  any category,  with an  affected emergency  flotation
    system (EFS) assembly  as defined in  European Aviation Safety  Agency
    (now European Union Aviation Safety Agency) (EASA) AD 2018-0279, dated
    December 14, 2018 (EASA AD 2018-0279).

    of the inflation hoses to the  tee manifolds of the inflation line  on
    the  EFS assembly.  The FAA  is issuing  this AD  to detect  incorrect
    installation of the  inflation hoses on  the EFS assembly.  The unsafe
    condition, if not addressed, could result in partial inflation of  the
    flotation bags in  a ditching event,  preventing a timely  egress from
    the helicopter and consequent injury to the helicopter occupants.

(f) COMPLIANCE

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

(g) REQUIREMENTS

    Except  as specified  in paragraph  (h) of  this AD:  Comply with  all
    required actions and compliance times specified in, and in  accordance
    with, EASA AD 2018-0279.

(h) EXCEPTIONS TO EASA AD 2018-0279

(1) Where EASA AD 2018-0279  requires compliance in terms of flight hours,
    this AD requires using hours time-in-service.

(2) Where EASA AD 2018-0279  requires compliance  from its effective date,
    this AD requires using the effective date of this AD.

(3) Where the service information required  by EASA AD 2018-0279 specifies
    recording  compliance  with  the service  bulletin  in  the helicopter
    logbook, this AD does not include that requirement.

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.

This proposed AD 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 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 FAA is proposing 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.

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.

FAA's Determination

These products 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 is proposing this AD
after evaluating all known relevant information and determining that
the unsafe condition described previously is likely to exist or develop
on other helicopters of the same type design.

Proposed AD Requirements in This NPRM

This proposed AD would 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 the EASA AD."

Explanation of Required Compliance Information

In the FAA's ongoing efforts to improve the efficiency of the AD
process, the FAA developed a process to use certain civil aviation
authority (CAA) ADs as the primary source of information for compliance
with requirements for corresponding FAA ADs. The FAA has been
coordinating this process with manufacturers and CAAs. As a result, the
FAA proposes to incorporate EASA AD 2018-0279 by reference in the FAA
final rule. This proposed AD would, therefore, require compliance with
EASA AD 2018-0279 in its entirety through that incorporation, except
for any differences identified as exceptions in the regulatory text of
this proposed AD. Using common terms that are the same as the heading
of a particular section in EASA AD 2018-0279 does not mean that
operators need comply only with that section. For example, where the AD
requirement refers to "all required actions and compliance times,"
compliance with this AD requirement is not limited to the section
titled "Required Action(s) and Compliance Time(s)" in EASA AD 2018-
0279. Service information specified in EASA AD 2018-0279 that is
required for compliance with it will be available at https://www.
regulations.gov by searching for and locating Docket No. FAA-2021-
0565 after the FAA final rule is published.

Differences Between This Proposed AD and the EASA AD

EASA AD 2018-0279 applies to Model AW189 helicopters, all serial
numbers (S/Ns), whereas this proposed AD would only apply 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, if adopted as proposed, would
affect 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 proposed AD.

Visually inspecting each EFS assembly would take 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 would take
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 products identified in this rulemaking action.

Regulatory Findings

The FAA determined that this proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD would 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 this proposed
regulation:

(1) Is not a "significant regulatory action" under Executive
Order 12866,

(2) Would not affect intrastate aviation in Alaska, and

(3) Would not have a significant economic impact, positive or
negative, on a substantial number of small entities under the criteria
of the Regulatory Flexibility Act.
