NTSB Factual Report

The certified flight instructor (CFI) and student pilot were practicing hovering. The student pilot had 6 hours total flight time, with all of his flight time being accrued in the accident make/model helicopter. During the hover, the right skid contacted the ground and the helicopter rolled onto its right side. The CFI reported that he delayed assuming control of the helicopter and allowed the helicopter to get too low during the maneuver.

NTSB Probable Cause

The student pilot's failure to maintain an adequate drift control and skid clearance from the ground and the CFI's inadequate supervision while hovering, resulting in dynamic rollover.
