On January 26, 1996, at 1300 central standard time, a Stinson 108-3, N653C, piloted by a private pilot, was substantially damaged when the airplane struck a snowbank during takeoff on runway 17 (2900'x60' asphalt) at the Sandstone Municipal Airport, Sandstone, Minnesota. Visual meteorological conditions prevailed at the time of the accident. The personal 14 CFR Part 91 flight was not operating on a flight plan. The pilot and two passengers reported no injuries. The pilot was contacted by the investigator in charge (IIC) on February 7, 1996. The pilot said the runway was completely covered with ice, and snowbanks five to eight feet high were present on both sides of the runway. The pilot reported that during takeoff roll he could not maintain directional control of the airplane. The pilot said there were no mechanical malfunctions with the airplane. The airplane's right wing was bent back approximately four feet, and the cowling was also bent as a result of the impact with the snowbank.
