FRILING/COTHERN LONGEZE

Analysis

THE PILOT MADE A STEEP RIGHT BANK WHILE ENTERING THE DOWNWIND LEG ON APPROACH TO LAND WHEN THE ENGINE QUIT AND THE PILOT WAS FORCED TO MAKE AN EMERGENCY LANDING IN A FIELD SHORT OF THE RUNWAY. UPON EXAMINATION OF THE FUEL SYSTEM THERE WAS A LACK OF FUEL IN THE LINES BETWEEN THE IN-LINE FUEL FILTER, ELECTRIC FUEL PUMP, ENGINE DRIVEN FUEL PUMP AND CARBURETOR. THE FUEL SYSTEM WAS PURGED OF AIR BY LOOSENING THE FUEL LINE AT THE CARBURETOR AND HAND CRANKING THE ENGINE. THE ENGINE WAS THEN STARTED AND RAN SATISFACTORILY. THE BUILDER OF THE EXPERIMENTAL AIRCRAFT STATED THAT IT HAD BEEN HIS EXPERIENCE THAT DURING A STEEP BANKED RIGHT OR LEFT TURN THE FUEL WILL PULL AWAY FROM THE FUEL SUMP OUTLET OF THE ENGINE, ALLOWING AIR TO ENTER THE FUEL LINES.
