Airworthiness Directives; Robinson Helicopter Company Helicopters
Summary
The FAA is adopting a new airworthiness directive (AD) for Robinson Helicopter Company (Robinson) Model R44 II helicopters. This AD requires inspecting the engine air induction hose (hose) and replacing any hose that is not airworthy. This AD was prompted by multiple reports of separation between the outer and inner layers of the hoses. The FAA is issuing this AD to address the unsafe condition on these products.
