THE PILOT WAS PERFORMING THE INITIAL TEST FLIGHT ON HIS HOMEBUILT AIRCRAFT. AFTER EXECUTING SEVERAL APPROACHES WITHOUT ACTUALLY LANDING THE AIRCRAFT, THE PILOT DECIDED TO MAKE A FINAL APPROACH TO A FULL STOP. AT APPROXIMATELY 800 FEET AGL, THE AIRCRAFT'S ENGINE EXPERIENCED A TOTAL LOSS OF POWER. THE PILOT EXECUTED A FORCED LANDING TO A FIELD. EXAMINATION BY THE FAA REVEALED THAT THE AIRCRAFT HAD ADEQUATE FUEL SUPPLY, BUT THE ENGINE FAILED AS A RESULT OF FUEL STARVATION CAUSED BY A MALFUNCTIONING FUEL SYSTEM VENT CHECK VALVE.
Probable Cause: THE FAILURE OF THE FUEL SYSTEM VENT CHECK VALVE, WHICH RESULTED IN FUEL STARVATION TO THE AIRCRAFT'S ENGINE.
