Narrative:The private pilot was demonstrating an autorotation with power recovery to his passenger. The deceleration and initial collective pitch pull was late, and rotor rpm was low. The pilot lowered the collective pich to increase rotor rpm and the helicopter started spinning to the left. Right antitorque pedal was applied with negative results, and the helicopter continued to spin through 360 degrees. The pilot lowered collective pitch and the helicopter collided with the terrain and rolled over on its left side. The pilot stated he made no attempt to stop the rotation by increasing throttle before the helicopter collided with the terrain.
Probable Cause: The pilot-in-command's improper use of the flight controls (cyclic and collective) during a simulated autorotation, resulting in an in flight collision with terrain and subsequent roll over.
