Amendment 39-21181; Docket No. FAA-2020-0215;
Product Identifier 2018-SW-088-AD.

TDATA NOTE: The FAA is correcting  a service bulletin reference  in the AD
            paragraph (g)(1).  This document corrects that error.  In  all
            other respects, the original document remains the same.

(a) EFFECTIVE DATE

    This AD is effective September 3, 2020.

(b) AFFECTED ADS

    None.

(c) APPLICABILITY

    This AD applies to the Leonardo S.p.A. helicopters identified in para-
    graphs (c)(1) through (3) of this AD, certificated in any category.

(1) Model AB139 and AW139 helicopters,  all serial numbers,  equipped with
    an emergency flotation system (EFS) float assembly  having part number
    (P/N) 3G9560V00332, 3G9560V00432, 3G9560V01432, or 3G9560V01532.

(2) Model AW169 helicopters,  all  serial  numbers,  equipped  with an EFS
    float assembly having any part number.

(3) Model AW189 helicopters,  all  serial  numbers,  equipped  with an EFS
    float assembly having P/N 8G9560V00331 or 8G9560V00431.

(d) SUBJECT

    Joint Aircraft Service Component (JASC) Code 3212, Emergency Flotation
    Section.

(e) REASON

    This AD was prompted by  reports of uncommanded deployment of  the EFS
    due to  improper accomplishment  of the  reset procedure  of the shape
    memory  alloy  (SMA) inflation  system  actuation device.  The  FAA is
    issuing this  AD to  address uncommanded  EFS deployment,  which could
    result in reduced control of the helicopter.

    ready done.

    helicopters) or P/N 8G9560V01751 (Model AW189 helicopters), as applic-
    able,  with a serial number specified  in Figure 1 to paragraph (g)(1)

Airworthiness Directives
; Leonardo S.p.A. Helicopters

AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).

ACTION: Final rule.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for
certain Leonardo S.p.A. (Leonardo) Model AB139, AW139, AW169, and AW189
helicopters. This AD was prompted by reports of uncommanded deployment
of the emergency flotation system (EFS) due to improper accomplishment
of the reset procedure of the shape memory alloy (SMA) inflation system
actuation device. This AD requires removal of affected SMA inflation
systems and installation of serviceable SMA inflation systems. The FAA
is issuing this AD to address the unsafe condition on these products.

DATES: This AD is effective September 3, 2020.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of September 3,
2020.

ADDRESSES: For service information identified in this final rule,

SUPPLEMENTARY INFORMATION:

Discussion

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 Model
AB139, AW139, AW169, and AW189 helicopters. The NPRM published in the
Federal Register on April 14, 2020 (85 FR 20618). The NPRM was prompted
by reports of uncommanded deployment of
the EFS due to improper accomplishment of the reset procedure of the
SMA inflation system actuation device. The NPRM proposed to require
removal of affected SMA inflation systems and installation of
serviceable SMA inflation systems. The FAA is issuing this AD to
address uncommanded EFS deployment, which could result in reduced
control of the helicopter.
The European Aviation Safety Agency (now European Union Aviation
Safety Agency) (EASA), which is the Technical Agent for the Member
States of the European Union, has issued EASA AD 2018-0208, dated
September 20, 2018 (referred to after this as the Mandatory Continuing
Airworthiness Information, or ``the MCAI''), to correct an unsafe
condition for certain Leonardo Model AB139, AW139, AW169, and AW189
helicopters. You may examine the MCAI in the AD docket on the internet
at https://www.regulations.gov by searching for and locating Docket No.
FAA-2020-0215.

Comments

The FAA gave the public the opportunity to participate in
developing this final rule. After the NPRM was published, the FAA
received a comment from one commenter. However, the comment addressed
neither the proposed actions nor the determination of the cost to the
public. Therefore, the FAA has made no changes based on this comment.

Conclusion

The FAA reviewed the relevant data and determined that air safety
and the public interest require adopting this final rule as proposed,
except for minor editorial changes. The FAA has determined that these
minor changes:
Are consistent with the intent that was proposed in the
NPRM for addressing the unsafe condition; and
Do not add any additional burden upon the public than was
already proposed in the NPRM.

Related Service Information Under 1 CFR Part 51


Leonardo Helicopters has issued Alert Service Bulletin (ASB) No.
139-533, dated August 30, 2018; ASB No. 169-099, dated August 30, 2018;
and ASB No. 189-195, dated August 30, 2018. This service information
describes procedures for removal of affected SMA inflation systems and
installation of serviceable SMA inflation systems (including correcting
the SMA inflation system by performing a reset procedure). These
documents are distinct since they apply to different helicopter models.
This service information 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.

Costs of Compliance

The FAA estimates that this AD affects 138 helicopters of U.S.
registry. The FAA estimates the following costs to comply with this AD:

Estimated Costs for Required Actions

Labor cost
Parts cost
Cost per product
Cost on U.S. operators
Up to 7 work-hours x $85 per hour = Up to $595
$*
Up to $595*
Up to $82,110*

* The FAA has received no definitive data that would enable the FAA to provide
parts cost estimates for the actions specified in this AD.

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.
