The operator reported that the student pilot had completed three solo touch and go landings and was returning to land on the ramp. While approaching the parking area, he was distracted by two aircraft on the ramp, and the helicopter began an uncontrolled yaw. The student pilot lowered the collective and arrested the yaw, but as the helicopter entered ground effect, he raised the collective, and the uncontrolled yaw resumed. The helicopter impacted the ground and sustained substantial damage to the fuselage, main rotor, and tail rotor.
The operator reported that there were no preaccident mechanical malfunctions or failures with the helicopter that would have precluded normal operation.
Probable Cause: The student pilot’s failure to maintain helicopter control which resulted in impact with the ground.
