NTSB Narrative Summary Released at Completion of Accident

The certified flight instructor (CFI) was providing flight instruction to the student pilot, who had accumulated about 3 hours of helicopter flight experience. According to the CFI, the student pilot was practicing hovering, when the helicopter descended "too low." The helicopter momentarily contacted the ground while drifting to the right, and rolled over. The CFI further stated he did not experience any mechanical malfunctions.

NTSB Probable Cause Narrative

The certified flight instructor's failure to maintain ground clearance and his delayed remedial action, which resulted in a rollover.
