The flight instructor asked the student to demonstrate an autorotation from a hover approximately 2 to 3 feet high. The CFI stayed on the controls throughout the maneuver. After they closed the throttle, the helicopter moved backwards and to the left. As the helicopter touched the ground, the rear portion of the left skid became imbedded in the runway surface and the aircraft rolled over onto its left side. The aircraft came to rest approximately 180 degrees from its original heading. The winds at the time were reported to be from a direction of 310 degrees at a velocity of 18 knots gusting to 22 knots. The CFI reported that they conducted all their maneuvers into the wind.
Probable Cause: The flight instructor's inadequate compensation for wind conditions, and his failure to maintain aircraft control. Contributing was wind gusts.
