Incident Overview
The airplane was on final approach to a 3,559-foot-long, 60-foot-wide asphalt runway. The pilot observed a twin-engine airplane on a taxiway near the runway and, uncertain whether it would use the runway, elected to go-around.
Go-Around and Engine Sputter
The pilot pushed the throttle full forward and kept his right hand on the power quadrant. During the climb out, the engine began to sputter and lose power. Looking down at the power quadrant, the pilot noticed that the engine mixture control was pulled back. He pushed the mixture control in and lowered the airplane's nose to avoid a stall.
Collision with Trees
Despite these actions, the airplane struck trees about 1/2 mile beyond the departure end of the runway.
Examination
Examination of the engine and associated controls did not reveal any pre-impact mechanical malfunctions.
