N107WB

The pilot stated that he departed the Augusta Regional Airport/Bush Field, Augusta, Georgia, enroute to the General Dewitt Spain Airport, Memphis, Tennessee. He departed using the fuel from both main fuel tanks. Approximately one half hour into the flight the pilot stated that he switched both engines to the auxiliary fuel tanks. Two hours into the flight the right engine ran out of fuel. He switched the right fuel selector back to the main tank and turned on the electric boost pump. The engine surged and quit again. The pilot contacted air traffic control for a heading to the nearest airport and turned 180 degrees toward Pryor Field, Decatur, Alabama. The left engine stopped, and he turned the left engine fuel selector to the left main tank. He turned on the electric fuel boost pump and the engine failed to start. The pilot advised air traffic control that he had a fuel problem, and would not make it to the airport. He feathered the propellers and made an emergency landing in a field. After the forced landing the pilot and occupants exited the airplane uninjured. The pilot inspected both right fuel tanks and found both tanks empty. He inspected the left auxiliary tank and found it full and the left main was found with a lot of fuel. He reported that when he switched the fuel tanks to auxiliary positions he must have accidentally place the left fuel selector in the cross feed position.
