Aircraft: Rotorway EXEC 162F 
Aircraft Damage: Substantial
Defining Event: Loss of control in flight
Injuries: 2 None
Flight Conducted Under: Part 91: General aviation - Personal

Analysis

The pilot of the experimental amateur-built helicopter reported that during takeoff, when the left skid was coming off the ground, he felt a small jerk, so he moved the cyclic to the left and forward. When the cyclic moved it hit the passenger’s left knee. The passenger “jerked” and the cyclic moved back to the right and the helicopter “instantaneously” rolled over to the right side and struck the ground. The pilot and the passenger were not injured, and the helicopter’s main rotor and tail boom sustained substantial damage. The pilot reported that there were no mechanical failures or malfunctions of the helicopter that would have precluded normal operation.

Probable Cause and Findings

The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The pilot’s failure to maintain control of the helicopter during takeoff.

Findings

Personnel issues Aircraft control - Pilot
