Manvel, TX, USA
N10935
Cessna 150L
During the cross-country flight, the pilot performed a forced landing following a loss of engine power. During the landing roll, the nose landing gear collapse in the rough terrain. Examination revealed there was fuel in both fuel tanks, and the fuel was blue in color with no visual evidence of debris or contamination. The fuel selector was found in the "ON" position. When the crankshaft was rotated, there was engine continuity to the accessory case, thumb compression on each cylinder, and operation of the magneto impulse coupling. The spark plugs exhibited moderate wear. Continuity was confirmed for the throttle and mixture cables from the cockpit to the carburetor. The carburetor bowl had impact damage. The carburetor accelerator pump operated. No debris was found on the fuel screens for the gascolator or the carburetor. The reason for the loss of engine power could not be determined.
