According to the NTSB, the check airman, who was seated in the left seat, announced he wanted to simulate an engine failure and practice an autorotation. He took control of the helicopter, reduced power and lowered the collective control. As he initiated recovery, the helicopter struck terrain and rolled over on its left side. The rotor blades were destroyed and the tail boom was severed.
