On Monday, July 19, 1993, at about 1400 eastern daylight time, N5817P, a Mooney M20J, operated by K L I Aero Services Inc. of Lauderdale Lakes, Florida, and piloted by Gary Wolf of Lauderhill, Florida, crashed during landing at Cooperstown Westville Airport, Cooperstown, New York. Instrument meteorological conditions prevailed and no flight plan had been filed. The certificated private pilot and passenger were not injured. The aircraft was substantially damaged. The flight was operated under 14 CFR 91 and originated in Albany, New York. The pilot made three unsuccessful attempts to land on runway 2. A witness reported that the pilot landed long with about 500 feet of runway remaining. He also stated that the pilot with 30 feet of runway remaining tried to go around. The pilot stated that his last approach seemed to be satisfactory. He stated that his airspeed was 70 knots and he touched down 1/4 way down the runway. "Raised flaps, applied brakes. Plane continued down runway skidding and locked brakes. When end of runway in view, attempted go- around. Unable to obtain speed...lowered nose to gain speed and then raised to avoid terrain. Stalled and dropped." The pilot stated that there was no mechanical malfunction and the accident could have been prevented if he had aborted the landing and diverted to an alternate airport with better conditions. According to an FAA inspector, the pilot was landing on a 2300 foot long, wet grass strip. The pilot reported that he applied the brakes, but he was unable to stop and exited the runway.
