Analysis

The pilot stated that when the flight was on final approach, 'the aircraft suddenly stopped flying and contacted the snow...came to a stop about 500 feet down the runway on the centerline. All 3 gears were folded back.' The airplane had been washed the night before and then rolled outside into -5 degree temperature. Ice was found in the airplane static system.
