The pilot took off on a cross-country flight with an estimated 6.5 hours of fuel on board. After about four hours of flight, he noted a total loss of engine power. He selected a forced landing area and maneuvered to land. During the final approach to touchdown, the nose of the airplane suddenly pitched up when the front seat passenger/pilot interfered with the flight control. Subsequently, the airplane collided with the ground in a nose low attitude. Examination of the airframe failed to reveal a mechanical problem. Functional examination of the engine revealed a plugged (blocked) fuel injector nozzle. Functional examination/check of the engine disclosed that the fuel consumption rate was high. With the injector plugged, fuel consumption was about 143 pounds per hour (pph). After it was repaired, the normal fuel rate was 107 pph. The airplane was equipped with a normal fuel quantity gage.
Probable Cause: a blocked fuel injector nozzle, which increased the engine fuel consumption; failure of the pilot to adequately monitor fuel consumption, which resulted in fuel exhaustion before the airplane reached the destination; and the passenger's interference with the flight controls during the emergency landing.
