On August 30, 1998, about 1730 eastern daylight time, a Cessna 172F, N7832U, registered to Hartford Holding Corporation, collided with a dirt mound when it overran the runway during landing at Pilot Country Airport, Spring Hill, Florida, while on a Title 14 CFR Part 91 personal flight. Visual meteorological conditions prevailed at the time and no flight plan was filed. The aircraft received substantial damage and the private-rated pilot and one passenger were not injured. The flight originated from Spring Hill, the same day, about 1700. The pilot stated he was performing a touch-and-go landing and the aircraft floated and touched down over half the way down the runway. He elected to make a go-around. When the aircraft would not climb to clear trees and telephone wires at the end of the runway, he aborted the go-around. The aircraft touched back down on the runway and he was unable to stop the aircraft before overrunning the runway. The aircraft collided with a dirt bank and nosed over.
