On February 15, 1995, about 1145 eastern standard time, N63HB, a Cessna CE-525, overran the runway on landing at Wauchula, Florida, while on a 14 CFR Part 91 Executive flight. The airplane is registered to and operated by M & M Air Inc. Visual meteorological conditions prevailed at the time and no flight plan was filed. The airplane was substantially damaged and the crew of two and one passenger reported no injuries. The flight originated from Crystal River, Florida, about 20 minutes earlier. The pilot-in-command stated that he crossed the runway threshold at an approach speed of 130 knots. He said normal Vref speed was 110 knots for the airplane, but he wanted to carry extra speed to compensate for the wind and turbulence encountered on final. He landed long and could not stop the airplane on the runway remaining. The airplane departed the end of the runway and came to rest after crossing a drainage ditch about 200 feet from the end of runway 18. FAA personnel examined the crash site and found evidence indicating the airplane touched down 2,304 feet from the approach end of the 4,000 foot runway. The Vref speed for the day should have been 108 knots which would result in a landing roll of 2,650 feet. The examination of the aircraft showed no evidence to indicate preimpact malfunctions of either the control, engine, fuel, or throttle systems.
