NTSB investigators used data provided by various entities, including, but not limited to, the Federal Aviation Administration and/or the operator and did not travel in support of this investigation to prepare this aircraft accident report.
The instructor in the skid-equipped helicopter reported that during hover practice he transferred the flight controls to the student while the helicopter was hovering about 3-feet AGL, instead of a normal 5-foot AGL hover. After a short time, the hover became unstable and he took the flight controls. However, the instructor was not able to regain control of the helicopter. The left skid contacted the ground and the helicopter rolled onto its side.
