The private pilot was receiving rotorcraft instruction and was on approach to land. As the helicopter passed through about 15 feet, the flight instructor was also on the flight controls. The airspeed was about 20 MPH, with a descent of 200-300 FPM. When the collective was raised the helicopter continued to descend, landed hard, and rolled over. When interviewed the flight instructor remembered the LOW ROTOR warning horn had sounded. Post accident examination of the engine and mechanical throttle compensator found no evidence of a mechanical failure. The helicopter manufacturer had published a safety notice which cautioned against airspeed of less than 30 knots until the descent rates were less than 300 FPM.
Probable Cause: the lack of supervision by the flight instructor which resulted in a low rotor condition and subsequent hard landing.
