## Narrative

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

PILOT WAS MAKING A DELIVERY FLIGHT FROM WATERVILLE, WA TO CHESTER, MONTANA.  APPROXIMATELY 10 MINUTES INTO FLIGHT THE ENGINE STARTED TO RUN ROUGH, SURGE,  AND BACKFIRE.  PILOT TURNED BACK TOWARDS AIRPORT AND TROUBLESHOOT.  PILOT COULD NOT FIGURE OUT ANYTHING AND DECIDED THAT THE AIRPORT WAS TOO FAR AWAY AND TO LAND THE AIRCRAFT IN A PLOWED FIELD.  THE PILOT SHUT THE ENGINE DOWN AND LANDED.  AS AIRCRAFT TRANSFERED WEIGHT TO GROUND THE WHEELS DUG INTO THE DIRT AND THE AIRCRAFT FLIPPED OVER AND SLID APPROXIMATELY 8 FEET.  PILOT EXITED THE AIRCRAFT WITHOUT INJURY.  INSPECTION OF THE AIRCRAFT DETERMINED THAT THE RIGHT 'P' LEAD HAD BROKEN THE MAIN/CENTER LEAD RIGHT AS THE WIRE ENTERS THE MAGNETO.  THE OUTER CLOTH COVERING AND THE WIRE SHIELDING SHOWED EVIDENCE OF HAVING BEEN BROKEN FOR QUITE SOME TIME.  SEVERAL STRANDS OF THE CLOTH WRAPPING ON THE 'P' LEAD HELD THE OUTER PORTION OF THE WIRE ATTACHED.  THE CENTER LEAD WAS ABLE TO INTERMITTENTLY GROUND TO THE WIRE SHIELDING CAUSING THE ENGINE TO SPUTTER AND BACKFIRE.  THE CHANGE IN ENGINE RPM CAUSED THE PROPELLER GOVERNOR TO FLUTUATE CAUSING THE ENGINE RPM TO SURGE BACK AND FORTH.
