NTSB Narrative Summary Released at Completion of Accident

According to the student pilot, he lifted the collective control of the helicopter and it began to turn left. The pilot lowered the collective control, applied right anti-torque input, and added power. The helicopter began spinning to the right, collided with a fence, and the helicopter rolled over on its right side and came to a stop. Examination of the helicopter revealed the tail boom separated from the airframe and the man rotor blades were buckled at the main rotor mass. The student pilot did not report a mechanical problem with the helicopter.

NTSB Probable Cause Narrative

The pilot's improper use of flight controls which resulted in a collision with a fence.
