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 AW189 helicopters. This AD was prompted by a report of an uncommanded deployment of the emergency life-raft system (ELS). This AD requires a one-time inspection of the life-raft installations and, depending on the results, accomplishing additional actions, 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 July 22, 2024.

The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of July 22, 2024.

ADDRESSES:

AD Docket: You may examine the AD docket at regulations.gov under Docket No. FAA-2024-0235; or in person at Docket Operations between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays.

SUPPLEMENTARY INFORMATION:

Background

EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2022-0214, dated October 21, 2022 (EASA AD 2022-0214), to correct an unsafe condition on certain serial-numbered Leonardo S.p.A. Model AW189 helicopters.

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 S.p.a. Model AW189 helicopters. The NPRM published in the Federal Register on February 27, 2024 (89 FR 14420). The NPRM was prompted by a report of an uncommanded deployment of the ELS. Subsequent investigation determined incorrect installation of its control cable could have caused the occurrence. The NPRM proposed to require a one-time inspection of the life-raft installations and, depending on the results, accomplishing additional actions, as specified in EASA AD 2022-0214.

The FAA is issuing this AD to address unintended activation and deployment of the ELS. The unsafe condition, if not addressed, could result in unintended activation and deployment of the ELS in flight with possible impact on the rotors, resulting in reduced control of the helicopter.

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 2022-0214 requires a one-time inspection of both the left- and right-side life-raft installations for certain serial-numbered helicopters and, depending on findings, replacing its control cable and checking the assembly, replacing a cable pulley cover, correcting the cable installation, and replacing the life-raft assembly, as applicable.

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 also reviewed Leonardo Helicopters Alert Service Bulletin No.189-315, dated October 20, 2022. This service information specifies procedures for inspecting the ELS.

Differences Between This AD and the EASA AD


[top] The service information referenced in EASA AD 2022-0214 specifies taking pictures, completing an inspection report, and sending removed parts to the page 51204 manufacturer, whereas this AD does not include those actions.

The service information referenced in EASA AD 2022-0214 cautions that step 3.3 shall be performed by trained operators or by authorized service stations only, whereas this AD requires that step to be accomplished by persons authorized under 14 CFR 43.3.

EASA AD 2022-0214 refers to the emergency life-raft assembly inspection as a "check," whereas this AD refers to that action as an "inspection" because that action must be accomplished by persons authorized under 14 CFR 43.3.

EASA AD 2022-0214 allows installing inoperative placard(s) in clear view of both pilots to defer certain corrective action, provided all flight crews are informed and, thereafter, the helicopter is operated accordingly. FAA regulations mandate compliance with placards. However, this AD does not require informing flight crews or operating the helicopter accordingly because compliance with such requirements in an AD is impracticable to demonstrate or track on an ongoing basis; therefore, a requirement to operate the aircraft in such a manner is unenforceable. Nonetheless, flight crews of the helicopters identified in the applicability must operate in accordance with the placard(s) in this AD.

Costs of Compliance

The FAA estimates that this AD affects 4 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.

Inspecting the left- and right-hand side life-raft installations will take approximately 4 work-hours for an estimated cost of $340 per helicopter and $1,360 for the U.S. fleet.

If required, replacing a control cable and inspecting the life-raft assembly will take approximately 1 work-hour and parts cost approximately $1,665 for an estimated cost of $1,750 per side. If required, replacing a pulley cover will take approximately 0.5 work-hour and parts cost approximately $100 for an estimated cost of $143 per side. If required, correcting the cable installation will take approximately 4 work-hours and cost approximately $340 per side. If required, replacing a life raft assembly will take approximately 4 work-hours and parts cost approximately $125,700 for an estimated cost of $126,040 per side.

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.
