What happened
The flight began with approximately 40 gallons of fuel remaining in the main tanks. Before departure, the pilot added an additional 10 gallons to each of the auxiliary tanks. The aircraft departed under hazy weather conditions for a short flight lasting approximately 10 minutes. During the downwind leg of the traffic pattern while preparing to land, the pilot switched the fuel selection from the auxiliary tanks back to the main tanks. As the aircraft turned onto the final approach course, both engines lost power simultaneously. The pilot was unable to restart the engines and landed the aircraft short of the runway. During the landing roll, the left main landing gear collapsed.
The investigation
Post-accident examination of the engines and fuel system revealed no preimpact discrepancies that would explain the loss of power. The right engine was successfully started after the accident and operated normally. The left engine could not be started due to damage sustained during the impact with the ground.
