ACTION : Final rule. SUMMARY : The FAA is adopting a new airworthiness directive (AD) for Robinson Helicopter Company (Robinson Helicopter) Model R22 Beta, R22 Mariner, R44, and R44 II helicopters with a certain governor controller installed. This AD was prompted by reports of engine governor failure, which was a result of water intrusion inside of the governor controller. This AD requires replacing certain governor controllers and prohibits installing those governor controllers on any helicopter. The FAA is issuing this AD to address the unsafe condition on these products. DATES : This AD is effective November 29, 2024. The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of November 29, 2024. ADDRESSES : AD Docket: You may examine the AD docket at regulations.gov under Docket No. FAA–2024–1886; or in person at Docket Operations between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays.

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 Robinson Helicopter Model R22 Beta, R22 Mariner, R44, and R44 II helicopters with a governor controller part number (P/N) D270–1, Revision A through E inclusive, installed. The NPRM published in the Federal Register on July 17, 2024 (89 FR 58084). The NPRM was prompted by three reports of governor controller failures involving Robinson Helicopter Model R22 Beta and R44 II helicopters. Prior to these governor controller failures, several operators notified Robinson Helicopter of a malfunction of the governor controller. As a result of an investigation, it has been determined VerDate Sep<11>2014 15:49 Oct 23, 2024 Jkt 265001 PO 00000 Frm 00010 Fmt 4700 Sfmt 4700 E:\FR\FM\24OCR1.SGM 24OCR1 lotter on DSK11XQN23PROD with RULES1

84809 Federal Register / Vol. 89, No. 206 / Thursday, October 24, 2024 / Rules and Regulations that the root cause for these malfunctions is water intrusion in the circuit board of the governor controller. In light of this, Robinson Helicopter issued service bulletins which specify exchanging the existing governor controller with a governor which provides additional moisture protection. In the NPRM, the FAA proposed to require removing any governor controller P/N D270–1, Revision A thru E inclusive, from service and installing a governor controller P/N D270–1, Revision F or later approved revision. In the NPRM, the FAA also proposed to prohibit installing governor controller P/N D270–1, Revision A through E inclusive, on any helicopter, since the affected parts may also be installed on Robinson Helicopter Model R22 Mariner and R44 helicopters. The unsafe condition, if not addressed, could result in loss of engine speed governing such as an engine overspeed or underspeed condition, and subsequent unexpected loss of power during critical phases of flight and landing. The FAA is issuing this AD to address the unsafe condition on these products. Discussion of Final Airworthiness Directive Comments The FAA received comments from one commenter, Robinson Helicopter, who stated that they had no comment. Conclusion The FAA reviewed the relevant data, considered the comment received, and determined that air safety requires adopting the AD as proposed. Accordingly, the FAA is issuing this AD to address the unsafe condition on these products. Except for minor editorial changes, this AD is adopted as proposed in the NPRM. Material Incorporated by Reference Under 1 CFR Part 51 The FAA reviewed Robinson Helicopter R22 Service Bulletin SB–121 and Robinson Helicopter R44 Service Bulletin SB–114, each dated June 28, 2023 (SB–121 and SB–114). This material specifies procedures for removing governor controller, part number D270–1, Revision A thru E, and replacing it with governor controller P/ N D270–1, Revision F (or subsequent). 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 also reviewed Robinson R22 and R44 Engine Monitoring Unit (EMU) Technician’s PC Software Guide, dated Oct 9, 2020. This material provides information to program the new EMU ID for the governor controller. Differences Between This AD and the Referenced Material The referenced material applies to Robinson Helicopter Model R22-series and R44-series helicopters with certain P/N D270–1 governor controllers installed and also identifies which serial-numbered helicopters the affected parts were factory installed on, whereas this AD applies to all Robinson Helicopter Model R22 Beta, R22 Mariner, R44, and R44 II helicopters with a certain P/N D270–1 governor controller installed. This AD requires accomplishing certain actions specified in SB–121 or SB–114, as applicable to your helicopter model, except the procedures in paragraph 4. of SB–121 and SB–114 must be accomplished by persons authorized under 14 CFR 43.3., instead of ‘‘an appropriately rated person.’’ Costs of Compliance The FAA estimates that this AD affects 140 helicopters of U.S. registry. Labor costs are estimated at $85 per work-hour. Based on these numbers, the FAA estimates the following costs to comply with this AD. Replacing the governor controller will take 2 work-hours and parts will cost $1,800 for an estimated cost of $1,970 per helicopter and $275,800 for the U.S. fleet. 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.

SUPPLEMENTARY INFORMATION : Authority for This Rulemaking The FAA’s authority to issue rules regarding aviation safety is found in Title 49 of the United States Code. 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. This rulemaking is promulgated under the authority described in Subtitle VII, Part A, Subpart I, Section 40103. Under that section, the FAA is charged with prescribing regulations to assign the use of the airspace necessary to ensure the safety of aircraft and the efficient use of airspace. This regulation is within the scope of that authority as it modifies the Air Traffic Service (ATS) route structure as necessary to preserve the safe and efficient flow of air traffic within the National Airspace System. History The FAA published a NPRM for Docket No. FAA 2024–0020 in the Federal Register (89 FR 3900; January 22, 2024), proposing to revoke J–179 and amend Q–10 in Alaska. Interested parties were invited to participate in this rulemaking effort by submitting written comments on the proposal to the FAA. One comment was received and was in favor of this action. Incorporation by Reference Jet Routes are published in paragraph 2004 and United States Area Navigation Routes are published in paragraph 2006 of FAA Order JO 7400.11, Airspace Designations and Reporting Points, which is incorporated by reference in 14 CFR 71.1 on an annual basis. This document amends the current version of that order, FAA Order JO 7400.11J, dated July 31, 2024, and effective September 15, 2024. FAA Order JO 7400.11J is publicly available as listed in the ADDRESSES section of this document. These amendments will be published in the next update to FAA Order JO 7400.11. FAA Order JO 7400.11J lists Class A, B, C, D, and E airspace areas, air traffic service routes, and reporting points.
