While on a 2 mile final approach to a runway, the airplane's engine lost power. The pilot was unable to restore full power, and could not maintain altitude. The airplane then struck trees about 50 feet above the ground. During preflight inspection, the right wing fuel tank drain was frozen, and had to be heated. The first two fuel samples revealed a small amount of water, but the third and fourth samples were clear. The left tank drain was not frozen, and contained a small amount of water. No water was detected in the filter drain. Examination of the wreckage, while the outside ambient temperature (OAT) was below freezing, revealed a small amount of water and contaminants in the carburetor bowl, and the fuel drain. When the fuel caps were removed, the sounds of the tanks expanding from the in rushing air were heard. After the wings were removed and placed in a heated hanger, approximately 1 cup of dirty water was found in the fuel tanks. The engine was test run satisfactorily. At the time of the accident, the OAT had been below freezing for the last 24 hours.
Probable Cause: Fuel vents blocked by frozen moisture which resulted in restricted fuel flow to the engine and subsequent loss of engine power.
