On July 9, 2000, at 1045 central daylight time, a Cessna 180, N4940A, piloted by a private pilot, sustained substantial damage during a nose over following a loss of control during landing rollout on runway 23 (3,000 feet by 75 feet, dry/asphalt) at the Saint Cloud Regional Airport, Saint Cloud, Minnesota. Visual metrological conditions prevailed at the time of the accident. The personal flight was operating under the provisions of 14 CFR Part 91 and was not on a flight plan. The pilot and three passengers reported no injuries. The flight departed the Ely Municipal Airport, Ely, Minnesota, at 0900. According to the pilot's written statement, "Entered pattern for runway 23. Perform[ed] 3-point full stall landing on runway 23. Twice during rollout the brakes grabbed hard enough to lift the tail off the ground. Toward the end of the rollout the right brake locked the tire." The pilot reported, "I maintained a straight ground track as long as possible with left full rudder and brake. When rudder effectiveness was lost the aircraft swiveled 90-degrees clockwise and skidded/slid down the runway and off into the grass." The pilot stated, "When aircraft slid into the grass the left main gear dug-in and was ripped out of the aircraft. The aircraft laid over on its left side breaking the left wing strut and wing." Post-accident examination of the wheel and brake assemblies revealed no anomalies that could have precluded the normal operation of the brake system. Examination of the tire treads on both main gear failed to reveal any flat spots in the tread pattern and no slippage was noted between the tires and the wheel assemblies.
