This amendment adopts a new Airworthiness Directive (AD) which imposes an inspection schedule on the overrunning clutch assembly P/N 369A5350-601 and -603 and a Retirement life on the P/N 369A5364 sprag assembly, which it contains, used in the Hughes Helicopter Model 369 Series Helicopters equipped with any cargo hook. This AD is needed to prevent an overrunning clutch assembly failure which will result in the loss of engine power to the main rotor resulting in a hazardous emergency landing.
