Primary finding
Probable cause
The pilot's failure to maintain adequate clearance from the ground, which resulted in a loss of control and subsequent dynamic rollover.
Investigator assessment
Analysis narrative
The pilot reported that while conducting a pedal turn at a hover over rough dirt and grass east of the taxiway, the right skid contacted the ground and became lodged. The helicopter subsequently spun and rolled on its right side. During the rollover, the helicopter's main rotor blades struck the ground which resulted in substantial damage to the main rotor blades and fuselage. The pilot reported no mechanical malfunction or failures with the helicopter that would have precluded normal operation.
