The flight instructor initiated a demonstration of a low altitude auto-rotation while moving forward in a hover at a "brisk walk." The planned touchdown site was to a grassy area slightly east of the runway environment and upon touchdown, the helicopter's skids encountered soft terrain and dug in and the helicopter rocked forward up onto the toes of the skids. Immediately thereafter, the main rotor blades contacted the ground and the helicopter came to rest on the forward skid toes and the main rotor mast. The instructor reported that there was no mechanical malfunction with the helicopter at the time of the event and the terrain at the selected site for the auto rotation was soft.
Probable Cause: The pilot's selection of unsuitable terrain for a practice auto rotation landing. A contributing factor was the soft terrain.
