Accident Summary

A private pilot was flying a multi-engine airplane and was approaching an airport for landing. During the approach, both engines began to surge. The pilot attempted to switch to the auxiliary fuel tanks, but inadvertently switched the left engine fuel selector to the off position. Subsequently, the left engine experienced a total loss of engine power. On final approach for landing, the airplane impacted terrain and was subsequently consumed by a postimpact fire. The fuel onboard the airplane at the time of the accident could not be determined.
