Docket No. 2003-SW-46-AD
Abstract
This amendment adopts a new airworthiness directive (AD) for Kaman Aerospace Corporation (Kaman) Model K-1200 helicopters. This action requires certain initial and repetitive visual inspections of the main rotor blade (blade) grips for a crack. If a crack is found, this AD requires replacing the blade grip before further flight. This amendment is prompted by an accident involving the loss of all blades because of a crack in a blade grip on the upper surface around the bolthole. The actions specified in this AD are intended to prevent failure of a blade grip, loss of a blade, and subsequent loss of control of the helicopter.
