NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

THE OWNER/PILOT OF A CESSNA 340A STATED THAT NEITHER HE NOR HIS INSTRUCTOR REPOSITIONED THE FUEL SELECTOR PRIOR TO FLIGHT AFTER A GROUND DEMONSTRATION OF THE FUEL CROSS-FEED SYSTEM, EVEN THOUGH A CHECK LIST HAD BEEN USED. DURING THE FLIGHT, BOTH ENGINES FAILED AND THE AIRCRAFT LANDED SHORT OF THE RUNWAY WHILE ATTEMPTING A FORCED LANDING AT THE STOCKTON AIRPORT. POST CRASH EXAMINATION OF THE FUEL SYSTEM REVEALED THAT THE LEFT TANK WAS EMPTY AND THE RIGHT TANK WAS FULL.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

THE PILOTS FAILURE TO PROPERLY POSITION THE FUEL SELECTOR PRIOR TO FLIGHT, AND THE FAILURE OF THE CHECK PILOT TO ADEQUATELY SUPERVISE THE CONDUCT OF THE FLIGHT.
