Rotorway Executive 162F, G-FLIT
Whilst in the cruise, the helicopter suddenly yawed and the engine rpm increased rapidly. The pilot closed the throttle and entered an autorotative descent. The subsequent landing was achieved with only minor damage to the helicopter. It was found that the loss of drive to the main rotor system was caused by the fatigue failure of a drive shaft. There was a history of shaft failures on this helicopter type, mostly involving an earlier design; this aircraft was equipped with the latest design standard.
