Accident Overview
A helicopter accident occurred during a training flight intended to demonstrate hover maneuvers to a prospective student with no prior helicopter flying experience. The flight, which had been uneventful for the first hour, involved a certified flight instructor (CFI) and the student.
Sequence of Events
After the initial uneventful flight, the CFI decided to practice hover maneuvers over a turf area adjacent to the airport helipad. The CFI briefed the student on the sensitivity of the helicopter controls during a hover and then passed over control. The student unsuccessfully attempted to perform a hover, after which the CFI regained control. Despite the earlier difficulty, the CFI elected to let the student try to hover again. As he relinquished control, the helicopter rolled to the left. The CFI attempted to correct the deviation, but during the recovery, the low rotor rpm warning horn sounded. He increased the throttle, but the skid made contact with the ground, and the helicopter rolled onto its side.
Damage
The helicopter sustained substantial damage to the rotor system and gearbox during the accident sequence.
