Full official abstract

This amendment adopts a new airworthiness directive (AD), applicable to Robinson Helicopter Company (RHC) Model R22 helicopters. This action requires replacing certain serial number sprag clutches with an airworthy sprag clutch as specified in this AD. This amendment is prompted by several reports of clutch assemblies with cracked or fractured sprag ends. The actions specified by this AD are intended to prevent a sprag clutch failure, loss of main rotor RPM during autorotation, and subsequent loss of control of the helicopter.
