Background


EASA, which is the Technical Agent for the Member States of the
European Union, has issued EASA AD 2021-0065, dated March 8, 2021 (EASA
AD 2021-0065), to correct an unsafe condition for certain serial-
numbered Leonardo S.p.A. Helicopters, formerly Finmeccanica S.p.A.,
AgustaWestland S.p.A., Agusta S.p.A., Model A109S and AW109SP helicopters.

This proposed AD was prompted by the discovery that rubber
protection of certain electrical wiring had not been installed in the baggage
avionics bay during production. The FAA is proposing this AD to prevent
chafing of electrical wiring, which could result in fire ignition and
smoke in the baggage compartment and subsequent loss of control of the
helicopter. See EASA AD 2021-0065 for additional background
information.

Related Service Information Under 1 CFR Part 51


EASA AD 2021-0065 requires installing rubber protections on the
electrical wiring in the baggage/avionics compartment.
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.

Other Related Service Information


The FAA reviewed Leonardo Helicopters Alert Service Bulletin (ASB)
No. 109S-100, dated February 2, 2021, for Model A109S helicopters, and
Leonardo Helicopters ASB No. 109SP-142, also dated February 2, 2021,
for Model AW109SP helicopters. This service information specifies
procedures for installing protective rubber borders on the edge of the
baggage avionics bay frames.

FAA's Determination


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 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 these same type designs.

Proposed AD Requirements in This NPRM


This proposed AD would require accomplishing the actions specified
in EASA AD 2021-0065, described previously, as incorporated by
reference, except for any differences identified as exceptions in the
regulatory text of this proposed 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 some 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 2021-0065 by reference in the FAA
final rule. This proposed AD would, therefore, require compliance with
EASA AD 2021-0065 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 2021-0065 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 2021-
0065. Service information referenced in EASA AD 2021-0065 for
compliance will be available at https://www.regulations.gov by
searching for and locating Docket No. FAA-2021-0834 after the FAA final
rule is published.

Costs of Compliance


The FAA estimates that this AD, if adopted as proposed, would
affect 3 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.

Installing protective rubber borders on the edge of the baggage
avionics bay frames would take about 2 work-hours and parts would cost
about $24 for an estimated cost of $194 per helicopter and $582 for the
U.S. fleet.

The FAA has included all known costs in its cost estimate.
According to the manufacturer, however, some of the costs of this
proposed AD may be covered under warranty, thereby reducing the cost
impact on affected operators.

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
