Incident Overview
A pilot experienced a dual engine failure after leveling off from a descent for a visual approach. The aircraft subsequently impacted terrain approximately one-quarter mile from the airport.
Pilot Report
The pilot reported switching to the main fuel tanks 12 miles from the airport and stated that each of the four tanks contained about 150 pounds of fuel.
Inspection Findings
Post-impact inspection of the aircraft revealed that the left auxiliary fuel tank contained only 0.25 gallons of fuel. The remaining tanks were ruptured due to impact forces, preventing accurate fuel quantity measurement.
Fuel Management
The aircraft's auxiliary fuel tanks are designed for use during cruise flight only. However, the pilot reported using the auxiliary tanks during the descent for landing, contrary to this operational limitation.
