According to the flight instructor (CFI), he and the student pilot were on an instructional flight, and the student was performing hovering autorotations to a clear, moist, sandy area of a river bed. The CFI reported that the student began an autorotation from a 3-foot hover when, about 1 foot above the ground, the helicopter began to drift to the left. The CFI took the controls and applied right cyclic as the rotor rpm continued to decay. His control input did not stop the helicopter's accelerating leftward movement. As the left skid touched down on sandy terrain, the helicopter experienced a dynamic rollover and rolled onto its left side. The wind at the accident site was estimated to be westerly at about 10 knots.
Probable Cause: the flight instructor's inadequate supervision and delay in taking remedial action to stop the aircraft's lateral movement, which resulted in a dynamic rollover after touchdown.
