Narrative:
The flight instructor and his student were practicsing 180-degree autorotation landings. Prior to initiating their last autorotation to the left, they climbed to 500 ft. agl. The student was at the controls and began a steeper turn in an attempt to reach the aiming spot, and the helicopter entered a slight dive. As the student rolled out to begin the flare, the helicopter was below 100 ft. agl.

The instructor then took control of the helicopter. He pushed forward to level the helicopter, then rolled the throttle and tried to pull up on the collective. The helicopter hit the ground in a level attitude, then became airborne again. During the impact sequence, the tail boom was severed.

The helicopter then spun three or four times and landed on its left side. According to the instructor, there was no mechanical malfunction with the helicopter.
