Airworthiness Directives; Leonardo S.p.a. Helicopters

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) 
for certain Leonardo S.p.a Model AW189 helicopters. This proposed 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 proposed AD would require 
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 proposed for incorporation by 
reference (IBR). The FAA is proposing this AD to address the unsafe 
condition on these products.

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

[[Page 37259]]

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.

List of Subjects in 14 CFR Part 39

reference, Safety.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 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:

Leonardo S.p.a.: Docket No. FAA-2021-0565; Project Identifier 2018-
SW-111-AD.

(a) Comments Due Date

    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,

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.
    (4) Where EASA AD 2018-0279 identifies all Model AW189 
helicopters, all serial numbers in the applicability, this AD is 
only applicable to Model AW189 with an affected EFS assembly as 
defined in the definitions paragraph of the EASA AD.
    (5) This AD does not require the ``Remarks'' section of EASA AD 
2018-0279.

(i) No Reporting Requirement
