On December 16, 2002, about 0945 eastern standard time, a Cessna A150M, N9852J, registered to and operated by Crystal Aero Group Inc., as a Title 14 CFR Part 91 instructional flight, ran off the runway and was damaged while landing at Crystal River, Florida. Visual meteorological conditions prevailed, and no flight plan was filed. The student pilot was not injured, and the airplane incurred substantial damage. The flight originated in Crystal River, Florida, the same day, about 0935. The student stated that he was performing a supervised solo flight, and had been told by his instructor to make full-stop landings each time. After an uneventful approach and landing, the student said he attempted to follow procedures as if it had been a touch-and-go landing. As he attempted to take off, he said his instructor called on the radio to remind him that it should have been a full-stop landing. He said he then closed the throttle, but applied "too much left brake" as he attempted to stop, and the airplane departed the runway, impacted the concrete structure supporting a runway light, and nosed over, incurring damage. Prior to the accident there were no mechanical failure or malfunctions to the airplane or any of its systems.
