Prior to departing for a planned round-trip flight, the pilot visually ascertained the quantity of fuel in the airplane's main fuel tanks, but relied on the fuel gauges to ascertain the quantity of fuel in the auxiliary fuel tanks. Prior to taking off for the return flight, the pilot did not look in any of the fuel tanks and estimated the airplane contained a total of 30 gallons of fuel that was distributed among the two main and two auxiliary tanks. Approaching the airport, the left engine sputtered and the pilot repositioned both fuel selectors from the main tanks to the auxiliary tanks position. The left engine did not restart. The pilot then attempted to provide fuel to the left engine by positioning its fuel selector into the cross-feed position. Moments later, both engines lost all power. At the time, the airplane was on short final approach for landing. As the airplane continued descending, the pilot again attempted to restore engine power and he switched the right engine's fuel selector to the right auxiliary tank. The right engine's power surged to red line and the airplane began to uncontrollably roll left. The pilot reduced the right engine's throttle to regain directional and lateral control, and the airplane impacted the underlying homes, coming to rest 2,100 feet short of the landing threshold. An examination of the airplane revealed no evidence of a preimpact mechanical malfunction with the airplane's fuel control system or engines. Only ounces of fuel were observed in fuel lines, and no evidence of fuel was found in tanks or in the underlying terrain.
