On March 3, 2001, at 0832 mountain standard time, a Cessna 152, N24950, was substantially damaged when it nosed over during landing rollout at Walker Field, Grand Junction, Colorado. The student pilot, the sole occupant in the airplane, was not injured. The airplane was being operated by I Fly Strand Aviation, Inc., under Title 14 CFR Part 91. Visual meteorological conditions prevailed for the solo-instructional local flight that originated approximately 30 minutes before the accident. The pilot had not filed a flight plan. According to the flight instructor, the student was practicing touch and go landings. The student said the landing appeared "normal," but the airplane "bounced up" following initial touchdown. The student said that the airplane bounced again, started going to the right, and then the "nose buckled." The airplane nosed over and came to rest inverted. The left wing, the engine mount, and the vertical stabilizer were bent.
