On November 13, 2004, approximately 1330 mountain standard time, a Bell 206B3, N130JH, operated by AV Enterprises, Inc., was substantially damaged when it struck a power transmission line while maneuvering near Eureka, Utah. Visual meteorological conditions prevailed at the time of the accident. The local flight was being conducted under the provisions of Title 14 CFR Part 91 without a flight plan. The commercial pilot and one passenger were not injured. The flight originated at Faust, Utah, at 1300. According to the pilot, he was following Highway 36 near Eureka, and was repositioning for a filming operation. As he approached a hill, he climbed to an altitude of approximately 100 feet agl. After cresting the hill, he scanned the area ahead. He stated that he noticed a series of power transmission poles, paralleling the right side of the road ahead, but did not see any on the left. The pilot descended to approximately 30 feet agl. As he leveled out, at approximately 40 knots, the helicopter struck a power transmission line that stretched across the road. The pilot stated that he saw a "flash," and felt the helicopter begin to "vibrate and shake." He stated that he had cyclic and collective control, and attempted a forced landing on the road. The helicopter impacted the road, slid approximately 50 yards into the right side ditch. When the helicopter came to a stop, it rocked up on its nose, and the main rotor blades struck the ground. As the main rotor assembly pitched backward, the main rotor blades severed the tail boom, and then the main rotor hub and blade assembly separated from the mast. The helicopter remained upright and on its landing skids. The pilot stated that after the accident, he surveyed the area and noticed a power transmission pole on the left side of the road that was approximately 190 yards from the series of power transmission poles that were paralleling the right side of the road.
