On September 9, 2000, at 2000 central daylight time, a Mooney M20 airplane, N866B, was substantially damaged when it impacted a fence during a forced landing following the loss of engine power during takeoff from the Gundys Airport near Owasso, Oklahoma. The private pilot and his two passengers were not injured. The airplane was registered to and operated by the pilot. Night visual meteorological conditions prevailed and a flight plan was not filed for the 14 Code of Federal Regulations Part 91 personal flight. The flight was originating at the time of the accident and was destined for Woodward, Oklahoma. During a telephone interview conducted by the NTSB investigator-in-charge, the 590-hour pilot stated that the flight departed Runway 17 and was approximately 20 feet above the ground when the engine lost power. The pilot attempted to land on the remaining part of the 2,600-foot runway; however, the airplane overran the runway, crossed a road, went through a fence, struck a tree, and came to rest in a field. According to the pilot, the landing gear and right wing separated from the airplane. The pilot reported that the Lycoming O-320-A3A engine, serial number 2102-27, had accumulated 230.0 hours since its last overhaul, and 60.0 hours since its last annual inspection. Moreover, the pilot stated that he drained a total of 30 gallons of fuel from the aircraft subsequent to the accident. The FAA inspector, who traveled to the accident site, was able to rotate the constant-speed propeller and achieve thumb compression on all four cylinders. The right magneto was removed, rotated manually, and found to be in working order. The propeller, throttle and mixture control cables were verified to be operational by the FAA inspector.
