On June 22, 2004, approximately 2015 mountain daylight time, a Cessna 170B, N2555C, piloted by a private pilot, was substantially damaged when it struck a fence and impacted a ditch during an aborted landing at Heber City Municipal Airport (36U), Heber City, Utah. Visual meteorological conditions prevailed at the time of the accident. The personal cross-country flight was being conducted under the provisions of Title 14 CFR Part 91 without a flight plan. The pilot was not injured, but his two passengers sustained minor injuries. The flight departed the Salt Lake City International Airport (SLC), Salt Lake City, Utah, approximately 1930, and was destined for 36U. According to the pilot, he landed "smoothly" on runway 3. The tail wheel bounced slightly and the airplane became airborne and drifted to the left of runway centerline. He added power to abort the landing. The airplane settled back onto the runway, then veered off the left side. It struck the airport boundary fence, rolled into a ditch, and nosed over. The vertical stabilizer was crushed, and the wing rear carry-through spar was bent.
