During arrival, the pilot entered a left downwind for runway 11 and proceeded to make a low pass over the strip to chase off cows. At approximately midfield, he initiated a climb and according to the passenger, when power was applied, the engine did not respond properly. A witness reported that he observed the aircraft begin a climbing right turn, and at that time, the engine sounded as if it were sputtering, then quit. This witness said the aircraft made a descending left turn and hit the ground, he believed the pilot was avoiding a wooded area. Another witness stated that the plane pitched down abruptly. The pilot received a head injury and did not remember details of the accident, but believed the carburetor heat was on and full flaps were extended.
