The FAA is adopting a new airworthiness directive (AD) for certain Robinson Helicopter Company Model R22 BETA, R44 and R44 II helicopters. This AD requires inspecting the engine RPM sensor wiring and installing a wiring kit. Even though this is considered an interim AD with the FAA still accepting comments, it still goes into effect within 15 hours time-in-service or 15 days after the effective date of June 29, 2022.
The AD requires inspecting the engine RPM sensor wiring for damage and, depending on the outcome, accomplishing repairs. This AD also requires modifying the governor wiring connection to the airframe harness by installing wiring kit KI-288 for Model R22 BETA helicopters and wiring kit KI-287 for Model R44 and R44 II helicopters. These inspections and repairs are also addressed in Robinson Helicopter Company R22 Service Bulletin SB-119 and Robinson Helicopter Company R44 Service Bulletin SB-111.
The complete AD is available here. To submit comments, follow the links in the AD or click here. Comments must be received by July 29.
