During approach to landing the pilot entered a steep (45 degree bank) left turn from base to final. The pilot stated that he did not realize it at the time, but this action unported the fuel line to the left engine, causing the engine to fail due to fuel starvation. When the pilot decided that he was too low on final approach, he elected to go-around and added power. At this time he became aware of the failure of the left engine, and retarded the throttles for an emergency landing short of the runway. The pilot was unable to control the aircraft and dragged the left wing tip and left main landing gear across the ground before coming to an abrupt stop. The aircraft flight manual warned against steep bank turns/slips/landings/takeoffs when the fuel tanks contain 17 gallons or less per tank. The pilot stated that he believed the aircraft fuel tanks contained 17-18 gallons each at the time of the accident.
