Abstract
This amendment adopts a new airworthiness directive (AD) for Kaman Model K-1200 helicopters. This action requires replacing certain unairworthy sprag clutches with airworthy sprag clutches. This amendment is prompted by two incidents of sprag clutch failure during external load operations. The actions specified in this AD are intended to prevent a malfunctioning transmission clutch, loss of drive to the main rotor system, and subsequent loss of control of the helicopter.
