The helicopter pilot was attempting to take off from a trailer to conduct an aerial survey. During the liftoff from the trailer, the helicopter rolled right and impacted the ground. Postaccident examination of the helicopter revealed that the right skid trailer tie-down had not been removed before the takeoff attempt. Both main rotors, the fuselage, and the tailboom sustained substantial damage. The pilot reported that there were no preaccident mechanical malfunctions or failures with the helicopter that would have precluded normal operation.

Probable Cause: The pilot's failure to remove the right skid trailer tie-down before attempting to take off, which resulted in a dynamic roll-over.
