Airworthiness Directives; Leonardo S.p.a. Helicopters

AGENCY:

Federal Aviation Administration (FAA), DOT.

ACTION:

Final rule.

SUMMARY:

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.

DATES:

This AD is effective January 24, 2022.

The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of January 24, 2022.

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.
