## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

PILOT STATED HE WAS ENROUTE TO MID CAROLINA REGIONAL AIRPORT (RUQ) FROM A PRIVATELY OWNED GRASS STRIP IN CONCORD, NC.  APPROXIMATELY 40 MINUTES INTO THE FLIGHT, THE ENGINE ?BURPED? AND SHORTLY AFTER BEGAN TO RUN ROUGH. THE FUEL SELECTOR WAS ROTATED FROM THE LEFT TANK TO BOTH WITH NO CHANGE IN ENGINE OPERATION.  CARBURETOR HEAT WAS NOT APPLIED. THE ENGINE QUIT 2 TO 3 MINUTES AFTER THE INITIAL TROUBLE BEGAN. AN ENGINE RESTART WAS UNSUCCESSFUL. THE PILOT MADE A HARD LANDING IN AN OPEN FIELD, WHERE THE NOSE WHEEL SEPARATED FROM THE GEAR, AND THE AIRCRAFT FLIPPED OVER COMING TO REST UPSIDE DOWN.

PRIOR TO FLIGHT, THE PILOT ADDED 8 GALLONS OF AUTOMOTIVE FUEL FROM GAS CANS THAT HAD BEEN SITTING FOR ABOUT SIX MONTHS. 14 GALLONS OF AVGAS WERE ALREADY PRESENT IN THE AIRCRAFT FUEL TANKS. AUTO FUEL AND AVGAS ARE APPROVED TO BE USED IN THIS ENGINE.

POST-ACCIDENT CONTINUITY OF CONTROLS WAS VERIFIED TO THE THROTTLE, MIXTURE AND CARB HEAT. THE FUEL HAD BEEN DRAINED FROM THE AIRCRAFT AND WINGS REMOVED BUT WAS PRESENT AT THE GASCOLATOR FUEL DRAIN. THE FUEL DID NOT HAVE A SMELL CONSISTENT WITH FRESH AUTO FUEL, POSSIBLY DUE TO ITS AGE OR BEING MIXED WITH THE AVGAS.

2 WEEKS POST-ACCIDENT THE ENGINE WAS SUCCESSFULLY RUN-UP USING AVGAS UNDER NTSB GUIDANCE.
