The flight instructor said, while practicing 180 degree autorotations, and "at approximately 150 feet agl, [the] descent rate increase[d] dramatically.' The flight instructor stated that he attempted to recover and flare with aft cyclic and down collective. He then added full throttle and raised the collective, in an attempt to land in a "skid level attitude." The helicopter, however, struck the ground hard, collapsing both skids and allowing the main rotor blade to sever the tail boom. The helicopter rotated "three or four times" before coming to rest off of the left side of the runway. An examination of the helicopters systems revealed no anomalies.
