Analysis

The flight instructor stated that the student, who had 13 hours of total flight time, completed the runup and the pre-takeoff check, and lifted the helicopter into a hover. As they started to hover-taxi forward, the student suddenly applied left cyclic, and the left skid struck the ground. Before the instructor could overpower the student, the helicopter went into a dynamic rollover, and came to rest on its left side.

The student pilot and certified flight instructor were not injured. The helicopter sustained substantial damage. Visual Meteorological conditions prevailed and no flight plan was filed for the local flight. The instructional flight was conducted under 14 CFR Part 91.
