## Analysis

AFTER COMPLETING SEVERAL AEROBATIC FLIGHTS, THE PILOT PROCEEDED TO ANOTHER AIRPORT TO OBTAIN FUEL. WHILE EN ROUTE, THE ENGINE LOST ALL POWER AND WOULD NOT RESTART. SUBSEQUENTLY, THE AIRCRAFT WAS DAMAGED DURING A FORCED LANDING IN A SOYBEAN FIELD. AN EXAMINATION REVEALED THERE WAS 12 GALS OF FUEL REMAINING. NO CONTAMINATION WAS FOUND IN THE FUEL SYSTEM. A CHECK OF THE ENGINE REVEALED NO DISCREPANCIES. AN INVERTED FUEL SYSTEM WAS INCORPORATED IN THE HOME BUILT AIRCRAFT. THE FLAP SYSTEM IN THE INVERTED FUEL SYSTEM WAS NOT STICKING. THE FUEL CAP WAS NOT VENTED, BUT THERE WAS A 1/4 INCH VENT LINE FROM THE TOP OF THE TANK TO THE BOTTOM OF THE FUSELAGE. THE VENT LINE WAS FOUND OPEN; HOWEVER, THE DRAIN TUBE ON THE BOTTOM OF THE FUSELAGE FACED AFT INSTEAD OF FORWARD.
