Analysis narrative
In a written statement the student pilot reported that the accident flight was his first attempt to hover the helicopter, solo. He reported that after his instructor exited the helicopter, and as he raised the collective in preparation for takeoff "The helicopter jumped into the air and moved to the right." He said that he inadvertently over corrected for the situation, and the helicopter started to move toward where his instructor was standing. In an effort to control the movement of the helicopter he "...immediately pulled the cyclic to rear." The helicopter's tail rotor subsequently struck the ground, and sustained substantial damage.
