[Docket No. FAA-2021-0834; Project Identifier MCAI-2021-00298-R]
RIN 2120-AA64


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 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. This proposed AD would require 
installing protective rubber borders on the edge of the baggage 
avionics bay frames, as specified in a 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 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

[[Page 54125]]

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.
