The pilot of the helicopter was taking off from a field at farm, and attempted to clear a driveway, when the left skid toe caught on the top of a wire fence. The pilot applied aft cyclic in an attempt to climb; however, the helicopter rolled to the left and impacted the ground. The main rotor, tail rotor, and airframe sustained substantial damage. Subsequent examination of the helicopter did not reveal any preimpact mechanical malfunctions which would have precluded normal operation. The pilot reported about 3,900 hours of total flight experience in rotorcraft, which included 160 hours in the same make and model as the accident helicopter. He further reported that the accident could have been prevented had he conducted a walk around of the takeoff area to better evaluate prospective hazards.
