Aerospatiale SE 3130 Alouette II crash near Mokelumne Hills, CA, United States

The pilot reported that after about 20 minutes of flight, he returned to a private runway. The pilot descended to the runway and he began a hover-taxi to the other end. While hovering, the right skid made contact with the grass adjacent to the runway. The helicopter rolled over on its right ride, damaging the main rotor blades. The pilot reported that he thought that the accident could have been prevented if he had a faster and quicker reaction time. The pilot reported that there were no pre-accident mechanical failures or malfunctions with the helicopter that would have precluded normal operation.
