On October 30, 1994, about 1016 eastern standard time, a Cessna 150L, N19264, registered to Crystal Aero Group Inc., operating as a 14 CFR Part 91 instructional flight, experienced a partial loss of engine power on initial takeoff climb at about 200 feet msl from the Crystal River-Homosassa Air Terminal. The commercial pilot/certified flight instructor turned towards the most desirable fairway on a golf course, and observed golfers on the fairway. An alternate fairway was selected, full flaps were lowered, and a forced landing was made to the unsuitable landing area. The airplane rolled about 250 feet before the right wing collided with a tree. The airplane sustained substantial damage, and the commercial pilot/certified flight instructor, and student pilot reported no injuries. Visual meteorological conditions prevailed and no flight plan was filed. The flight originated about 2 minutes before the accident. Examination of the engine assembly and accessories by the FAA, and the Director of Maintenance for Crystal Aero Group Inc., revealed no evidence of a precrash failure or malfunction. The engine was started, and the partial loss of engine power could not be duplicated.
