According to the pilot, he was practicing touch and go landings on runway 5, a 6,404-foot-long, 150-foot-wide runway. During the takeoff roll following his eighth landing, the pilot felt "a gust of wind pushing…the plane to the left." He applied full right aileron, but could not arrest the turn. The pilot then applied the brakes, but the airplane departed the left side of the runway, impacted a ditch, and came to rest inverted, resulting in substantial damage to the firewall, wings, and vertical stabilizer. During a subsequent examination of the wreckage, a Federal Aviation Administration inspector found the flaps in the FULL, 30-degree position. The inspector also reported that there were no preexisting mechanical anomalies with the airplane. Winds, recorded at the airport about the time of the accident, were from 350 degrees true at 7 knots.
