On August 31, 2001, at 1415 central daylight time, a Piper PA-28 airplane, N525Z, registered to and operated by the pilot, was substantially damaged during a forced landing following a partial loss of power after takeoff from runway 35 at the Harvey Young Municipal Airport, Tulsa, Oklahoma. The commercial pilot and his passenger were not injured. Visual meteorological conditions prevailed and a flight plan was not filed for the 14 Code of Federal Regulations Part 91 personal flight. The local flight was originating at the time of the accident. On the NTSB Pilot/Operator Aircraft Accident Report, the pilot reported that shortly after takeoff at an altitude estimated to be between 100 to 150 feet agl, the engine lost power but continued to run. A gradual turn was initiated as he prepared for a forced landing. "Enough power was being developed to turn the airplane and get it over airport property." The airplane impacted rough sloping terrain, where the left main gear broke off, and skidded into a thick brush area. The reason for the partial loss of engine power was not determined.
