Airworthiness Directives; Robinson Helicopter Company Helicopters Federal Register ↗

Abstract

The FAA proposes to adopt 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 proposed AD was prompted by reports of engine governor failure, which was a result of water intrusion inside of the governor controller. This proposed AD would require removing certain governor controllers from service and installing a part eligible for installation. This proposed AD would also prohibit installing certain governor controllers on any helicopter. The FAA is proposing this AD to address the unsafe condition on these products.
