On February 16, 1995, at 1100 Pacific standard time, a Cessna 172M, N9512H, was found inverted off the runway at Corona, California. The aircraft was substantially damaged and the three occupants received minor injuries. Visual meteorological conditions existed at the time. No flight plan was filed for the local pleasure flight. Information from the pilot indicated that the initial takeoff on runway 25 was routine, but the acceleration was slow. About halfway down the runway, at a speed of about 50 to 55 knots indicated airspeed, the pilot decided to abort the takeoff. He reduced the throttle, retracted 10 degrees of flaps, and applied brakes. The right brake locked and caused skidding. The aircraft departed the runway and proceeded along the right side of the runway in soft grass. The nose gear caught in the grass and the aircraft came to rest inverted. The pilot reported that the winds were down the runway at 10 knots. A Federal Aviation Administration inspector examined the aircraft brake system and the airspeed indicator and found no malfunctions to either system.
