Analysis narrative
The pilot was lifting off from a field near a road with obstructions to the north, east, and south. During the departure to the west, the helicopter collided with a transmission line and the helicopter landed hard on the highway. The fuselage and main rotor blades sustained substantial damage. The pilot reported that there were no preaccident mechanical malfunctions or failures with the helicopter that would have precluded normal operation. He stated that the accident could have been prevented if he had performed a confined area takeoff.
