FAA-2024-1477; Project Identifier AD-2023-01015-R; Amendment 39-22880; AD 2024-23-01] RIN 2120-AA64 Airworthiness Directives; Robinson Helicopter Company AGENCY: Federal Aviation Administration (FAA), DOT. ACTION: Final rule. SUMMARY: The FAA is adopting a new airworthiness directive

(AD)for certain Robinson Helicopter Company Model R44 and R44 II helicopters. This AD was prompted by several reports of failed clutch actuators and failed rivets attaching the belt tension clutch actuator brackets (bracket) to the fan scroll housing. This AD requires inspecting each bracket and, depending on the results, accomplishing additional inspections or taking any necessary corrective actions. The FAA is issuing this AD to address the unsafe condition on these products. DATES: This AD is effective January 7, 2025. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of January 7, 2025. ADDRESSES: *AD Docket:* You may examine the AD docket at *regulations.gov* under Docket No. FAA-2024-1477; or in person at Docket Operations between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays.

(562)627-5226; email: *Charles.L.Ayala@faa.gov.* SUPPLEMENTARY INFORMATION: Background The FAA issued a notice of proposed rulemaking

(NPRM)to amend 14 CFR part 39 by adding an AD that would apply to certain serial-numbered Robinson Helicopter Company Model R44 and Model R44 II helicopters. The NPRM published in the **Federal Register** on June 27, 2024 (89 FR 53534). The NPRM was prompted by five reports of failed clutch actuators and failed rivets attaching the clutch actuator bracket, part number A185-1, A185-2, and A185-5 (bracket), to the fan scroll housing on Robinson Helicopter Company Model R44 II helicopters. According to Robinson Helicopter Company, in all of these occurrences, the bracket separated from the fan scroll housing. In four of the reports, this separation of the bracket caused a failure of the belt tension actuator. Further investigation revealed the failure of the rivets attaching the bracket to the fan scroll housing was caused by excessive vibration of the fan scroll housing due to the design of the fan scroll housing, including the quantity and size of the rivets. Because of design similarity, Robinson Helicopter Company Model R44 helicopters are also affected by this unsafe condition. In the NPRM, the FAA proposed to require, with the fanwheel removed, inspecting each bracket for looseness and fretting. Depending on the results of the inspection in the NPRM, the FAA proposed to require additional actions such as inspecting the fiberglass and rivet holes of the fan scroll housing for delamination, inspecting the quantity and size of the fan scroll housing rivets, replacing the fan scroll housing, replacing brackets and rivets, and applying a horizontal torque stripe to each rivet. The FAA is issuing this AD to address the unsafe condition on these products. Discussion of Final Airworthiness Directive Comments The FAA received a comment from one commenter, Robinson Helicopter Company. The following presents the comment received on the NPRM and the FAA's response to the comment. Request To Change the Applicability Robinson Helicopter Company requested the FAA revise the applicability paragraph to identify only riveted A185-1, A185-2, and A185-5 brackets. Robinson Helicopter Company stated that some helicopters within the applicable serial number ranges have been retrofitted with the latest design installation that utilizes screws as the method of attachment to the fan scroll housing instead of rivets and are not subject to this AD. The FAA agrees and has revised the applicability paragraph of this AD to clarify that only certain riveted brackets are applicable. The FAA also added a note to the applicability paragraph of this AD to further clarify that brackets installed to the fan scroll housing with screws are not applicable to this AD. Conclusion The FAA reviewed the relevant data, considered the comment received, 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 products. Except for minor editorial changes and other changes described previously, this AD is adopted as proposed in the NPRM. None of the changes will increase the economic burden on any operator. Material Incorporated by Reference Under 1 CFR Part 51 The FAA reviewed Robinson Helicopter Company R22 Service Letter SL-74B (SL-74B), and R44 Service Letter SL-61B (SL-61B), each Revision B and dated March 16, 2023 (co-published as one document). This material specifies procedures for inspecting the A185 brackets for looseness and ensuring that a total of 12 rivets attach the A185 brackets to the fan scroll housing, and corrective actions as necessary including repairing rivet holes; replacing the scroll; replacing any 1/8 -inch rivets with 5/32 -inch rivets; enlarging rivet holes; and applying a torque seal. SL-61B is incorporated by reference in this AD. SL-74B is not incorporated by reference in this AD because this AD does not apply to Robinson Helicopter Company Model R22 helicopters. 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 Material The FAA reviewed Robinson Helicopter Company R44 Service Bulletin SB-113, dated March 16, 2023 (SB-113). This material specifies procedures for inspecting the A185 brackets to ensure the brackets are attached to the fan scroll housing with 5/32 -inch rivets. This material also specifies repairing the scroll if there are less than 12 rivets, if 5/32 -inch rivets are not installed, if the brackets are loose, or if there is any fretting. Differences Between This AD and the Referenced Material This AD requires inspecting the brackets for fretting, and the fiberglass and rivet holes for delamination, whereas SL-61B does not contain those actions. SL-61B specifies procedures for repairing the fan scroll housing rivet holes, whereas this AD requires making that repair in accordance with FAA-approved procedures. Costs of Compliance The FAA estimates that this AD affects 1,686 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 brackets (three brackets per helicopter) for looseness and fretting will take 0.25 work-hour, for an estimated cost of $21 per helicopter and $35,406 for the U.S. fleet. If required, inspecting the fiberglass for delamination will take 0.25 work-hour, for an estimated cost of $21 per helicopter. If required, replacing the fan scroll housing will take 5 work-hours and parts will cost $3,720, for an estimated cost of $4,145 per helicopter. If required, inspecting all brackets, each inner plate, and each fan scroll housing rivet hole will take 1 work-hour, for an estimated cost of $85 per helicopter. If required, replacing a bracket or inner plate will take 1 work-hour and parts will cost $175, for an estimated cost of $260 per part replacement. If required, repairing each rivet hole (per bracket) will take 1.5 work-hours for an estimated cost of $128 per bracket. Replacing a rivet (if required) and applying a torque stripe to each rivet will each take a minimal amount of time with a nominal parts cost. 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.
