Aircraft Accident/Incident Report

Murrieta, California 92563
Monday, July 9, 2012 10:15 PDT

NTSB Narrative Summary Released at Completion of Accident

During an instructional flight, the student pilot reported that the instructor was demonstrating a “fast landing” approach to a hill. The instructor subsequently positioned the helicopter in a 3- to 4-foot hover above the ground and heading into the wind, then initiated a left pedal turn and started to lift off. The student stated that the helicopter suddenly rolled rapidly to the right and the main rotor blades contacted the ground, which resulted in a rollover. A postaccident examination of the airframe and engine revealed no evidence of mechanical malfunctions or failures that would have precluded normal operation. The terrain surrounding the accident site was covered with sporadic patches of sagebrush ranging from 1 to 4 feet high. It is likely that the helicopter contacted brush as the pilot performed the left hovering turn, which resulted in a dynamic rollover.

NTSB Probable Cause Narrative

The pilot's failure to maintain clearance from high vegetation while making a hovering turn, which resulted in a dynamic rollover.
