The student pilot reduced engine power to initiate the maneuver, pushed forward on the cyclic, and the helicopter descended. The flight instructor stated that he assumed cyclic control, and then the helicopter impacted the ground "fairly hard and bounced." The student pilot subsequently pulled up on the collective, the left skid remained in contact with the ground, and the helicopter rolled over on its left side. The flight instructor stated that there were no mechanical or performance deficiencies with the helicopter.

Probable Cause and Findings
