Incident Description
During flight, the pilot switched the fuel tanks from the auxiliary to the main position. Following this action, the left engine lost power. The pilot reported that the left selector lever was 'very stiff and hard to move.' Attempts to recycle the selector lever did not resolve the problem. With only the right engine providing power, the aircraft could not maintain level flight.
Forced Landing
Realizing the aircraft would not reach an airport, the pilot selected a suitable landing area along a dirt road. As the aircraft entered the landing flare, the left engine suddenly produced a burst of power. This power surge induced a severe yaw and roll, causing the left wing to contact the ground.
Post-Incident Examination
An FAA inspector examined the aircraft and found that the cable for the left selector valve was binding. The valve was found in an intermediate position between the main and auxiliary fuel tank positions.
