Analysis

According to the pilot, while maneuvering from base to final, he noticed the fuel control condition lever was in the cut-off position, which subsequently resulted in fuel starvation and a total loss of engine power. He immediately pushed the power, propeller, and condition levers full forward, but did not observe an expected increase in power. After an unsuccessful attempt to restart the engine, the airplane landed in a cotton field short of the intended runway. Postaccident examination of the airplane revealed that substantial damage to the left wing and aileron. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
