The pilot made an off airport forced landing following a loss of engine power about 2 minutes after departure. The pilot preflighted the airplane, drained fuel, and completed an extensive run-up. He taxied to the fuel pumps and added over 18 gallons of fuel. He did another run-up and departed. About 75 feet agl the engine sputtered and lost power. The pilot was unable to regain power so he attempted to land on a dirt road. The left wing contacted upsloping terrain; the right wing contacted trees and separated from the airplane. All engine controls and the carburetor air box were secure and functioning. The magnetos were timed to within 1 degree of each other, and the spark plugs were not discolored. All cylinders except cylinder No. 5 had compression greater than 70/80; cylinder No.5 was 25/80. Mechanics staked the valve, but the compression did not change. The gascolator contained 3 ounces of fuel. The carburetor contained a small amount of water; however, the fuel selector valve and main fuel line to the carburetor only contained fuel. The tank vents were clear.
Probable Cause: a loss of engine power due to water contamination forced the pilot to land in an unsuitable area resulting in collision with a tree.
