The inadequate supervision by the flight instructor by allowing the student to lose excessive altitude resulting in a skid impacting the ground and subsequent roll over of the helicopter.

Read the full NTSB narrative

The certified flight instructor decided to let the student perform one more steep turn before returning to the hangar. On the last steep turn the student lost more altitude than on previous maneuvers. The instructor took over the controls; however, the helicopter touched down right skid lower than the left with forward left lateral movement resulting in a roll over of the helicopter. The flight instructor stated there were no mechanical failures or malfunctions to the helicopter or any of its systems prior to the accident.
