On January 3, 2003, approximately 1200 cst, a Cessna 182S (Skylane), N2724R, piloted by a student pilot, was substantially damaged when it departed the runway surface and impacted a snowbank at the St. Louis Regional Airport (ALN), Alton, Illinois. The pilot was practicing takeoffs and landings on runway 35 (6,500 feet x 100 feet, asphalt) and was attempting a takeoff when the accident occurred. Visual meteorological conditions prevailed at the time of the accident. The solo-instructional flight was conducted under the provisions of 14 CFR Part 91 and was not on a flight plan. The pilot reported no injuries. In his written statement, the pilot noted that he was practicing takeoffs and landings in the local traffic pattern. He reported completing one takeoff and landing, and was attempting to takeoff again when the accident occurred. The pilot stated: "...after landing I straightened up and applied full power for takeoff .... Started veering to left and could not bring plane back to center. When I realized I was headed off of [the] runway, I pulled power and hit 15" high snow bank." He noted that he was afraid of overcontrolling and did not apply brakes. He estimated that the airplane's speed was 60 knots when it impacted the snowbank. The pilot noted that the ALN automatic terminal information service (ATIS) received prior to requesting a taxi clearance reported the braking action on runway 35 as "poor". In his statement, the pilot reported the runway conditions as "ice, wet". He reported no failures or malfunctions associated with the aircraft, either prior to, or at the time of the accident.
