Primary finding
Probable cause
The student pilot’s improper pitch control during landing, which resulted in a dynamic rollover.
Investigator assessment
Analysis narrative
The helicopter instructor reported that, during the approach to land, about 5 ft above the ground, the student pilot overcorrected and moved the cyclic "back hard and slightly right." The right rear skid contacted the ground, and the helicopter rolled to the right. The main rotor blades struck the ground, and the helicopter came to rest on its right side. The student reported that he believed the skid strike and unusual attitude were caused by his inexperience. The helicopter sustained substantial damage to the main rotor blades, the fuselage, and the tailboom. The flight instructor reported that there were no preaccident mechanical failures or malfunctions with the helicopter that would have precluded normal operation.
