Narrative:
The certified flight instructor (CFI) and student pilot had been performing hover practice. During an ascent to a hover, the helicopter drifted left and rearward, and the main rotor RPM decayed. The CFI took over the controls and attempted to stabilize the helicopter, when the helicopter's tail rotor struck the ground. The helicopter then spun 720 degrees, struck the ground and rolled over. Examination of the wreckage revealed no preimpact failure of the helicopter controls or drive train.

Probable Cause: the flight instructor's inadequate supervision in that he delayed corrective action in recovering the low rotor RPM resulting in a loss of control.
