The certified flight instructor was providing instruction to the private pilot, who was training for a commercial rating. While practicing a 180-degree autorotation, a downdraft was encountered approximately 200 feet above ground level (agl), and the helicopter made a hard landing. The flight instructor stated, "I said that I had [the] controls and proceeded to bring back the power at about 150 feet agl. Everything was good; rotor and engine rpm were in the green. I pulled collective up as I've done in previous situations, but this time it was different. I pulled collective, but it was almost as if the helicopter couldn't fly out of it." No anomalies were reported with the helicopter.
Probable Cause: The flight instructor's failure to maintain aircraft control during the flare/touchdown while practicing an autorotation which resulted in a hard landing. A factor which contributed to the accident was the downdraft wind condition.
