The 42-hour student pilot was performing solo touch-and-go crosswind landings to Runway 09. On the fifth and final landing, the single-engine airplane swerved unintentionally and exited the right side of the 3,455-feet long, by 40-feet wide asphalt runway. Moments later the nose landing gear fork fractured and the airplane nosed over, coming to rest in the inverted position. The pilot was able to exit the airplane unassisted. The vertical stabilizer and rudder sustained structural damage. An examination of the airplane's flight controls revealed no mechanical failure or malfunction. The weather observation facility located about sixteen nautical miles west from the site of the accident reported winds from 170 degrees at 5 knots.
