Narrative:
The commercial pilot, under the supervision of the flight instructor, initiated a full-touchdown autorotation in an unmowed, grassy practice area. After touchdown, the helicopter began a slow ground run for three to five feet with no abnormalities. The flight instructor and commercial pilot then reported a very hard hop, and the helicopter collided with the ground and began gyrating violently. Both pilots shut it down. Examination of the helicopter revealed the main rotor severed the tail boom, separating it from the airframe. The pilots reported no mechanical failures.

Probable Cause: The pilot's improper flare during practice autorotation.
