Abstract

The FAA is adopting a new airworthiness directive (AD) for certain Leonardo S.p.a. Model A109S and AW109SP helicopters. This 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 AD requires 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 incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.

SUPPLEMENTARY INFORMATION:

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.
    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 by adding an AD that would apply to Leonardo S.p.a. Model 
A109S and AW109SP helicopters as identified in EASA AD 2021-0065. The 
NPRM published in the Federal Register on September 30, 2021 (86 FR 
54124). The NPRM was prompted by the discovery that rubber protection 
of certain electrical wiring had not been installed in the baggage 
avionics bay during production. The NPRM proposed to require installing 
protective rubber borders on the edge of the baggage avionics bay 
frames, as specified in EASA AD 2021-0065.
    The FAA is issuing this AD to prevent chafing of electrical wiring, 
which if not addressed, 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.

Discussion of Final Airworthiness Directive

Comments

    The FAA received no comments on the NPRM or on the determination of 
the costs.

Conclusion

    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 reviewed the relevant 
data and determined that air safety requires adopting this AD as 
proposed. Accordingly, the FAA is issuing this AD to address the unsafe 
condition on these helicopters.

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.

Costs of Compliance

    The FAA estimates that this AD affects 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 AD.
    Installing protective rubber borders on the edge of the baggage 
avionics bay frames will take about 2 work-hours and parts will 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 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

    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.
