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.
