THE PILOT REPORTED THAT AFTER TAKEOFF, HE REMAINED AT A LOW ALTITUDE TO MANEUVER AROUND CLASS B AIRSPACE. ABOUT TEN MINUTES INTO THE FLIGHT, 'THE FUEL PRESSURE DROPPED TO ZERO' AND THE ENGINE LOST POWER. DURING THE FORCED LANDING, THE 'GEAR CAUGHT IN MUD,' COLLAPSED AND THE AIRPLANE NOSED OVER. IN HIS WRITTEN STATEMENT, THE PILOT REPORTED THAT 'PRIOR TO TAKEOFF, ON SEVERAL PREVIOUS FLIGHTS, FUEL SELECTOR WAS HARD TO MOVE.' EXAMINATION OF THE FUEL SYSTEM REVEALED NO EVIDENCE OF PREIMPACT MALFUNCTION. THE FUEL SELECTOR VALVE FUNCTIONED NORMALLY WHEN TESTED, HOWEVER, THE VALVE WAS VERY DIFFICULT TO OPERATE FROM THE PILOT'S SEAT. IT WAS POSITIONED NEAR THE FRONT LEFT CORNER OF THE SEAT, AND ACCORDING TO A FEDERAL AVIATION ADMINISTRATION INSPECTOR, WAS 'DIFFICULT TO MANIPULATE, AND IT WAS DIFFICULT TO DETERMINE WHICH TANK WAS SELECTED OR IF THE VALVE WAS IN THE PROPER POSITION.'
Probable Cause: the pilot's operation of the airplane with a known deficiency in the fuel selector, and his improper positioning of the fuel selector. A factor relating to the accident was: the fuel selector's restriction of movement.
