Analysis

The aircraft was cruising at 3500 feet when it lost power and made a forced landing on a road. It struck a pothole during landing rollout and directional control was lost with the aircraft receiving substantial damage. On scene investigation by the FAA showed the gascolator full of ice and the right fuel drain was frozen. Later the aircraft was warmed up in a hangar and 1/2 gallon of water was removed from the right wing. Water was also found in the engine fuel control inlet screen.
