## Narrative

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

PILOT DEPARTED LEESBURG, FL (KLEE) AIRPORT AT APPROXIMATELY 12:30 EST FOR A FLIGHT TO CANNON CREEK AIRPARK, FL.  AFTER APPROXIMATELY ONE HOUR OF FLIGHT, AND 10 MILES SOUTH OF DESTINATION, PILOT EXPERIENCED A LOSS OF ENGINE POWER AT 2000 FEET, WHILE DESCENDING FROM CRUISE ALTITUDE.  PILOT NOTIFIED LAKE CITY MUNICIPAL AIRPORT THAT HE HAD AN EMERGENCY AND WAS PREPARING FOR AN EMERGENCY LANDING.  PILOT FOUND A SUITABLE LANDING AREA AND PREPARED AIRCRAFT FOR AN EMERGENCY LANDING.  AIRCRAFT TOUCHED DOWN ON A FRESHLY PLOWED FIELD AND KEPT NOSE LANDING GEAR OFF THE SURFACE AS LONG AS POSSIBLE.  AIRCRAFT SLOWED DOWN TO A POINT IN WHICH THE AIRSPEED COULD NO LONGER KEEP NOSE LANDING GEAR OFF THE SURFACE, WHEN IT CONTACTED THE SOFT SURFACE.  NOSE LANDING GEAR SANK INTO SOFT GROUND AND ABRUPTLY STOPPED THE FORWARD MOTION OF THE AIRCRAFT. REMAINING KINETIC ENERGY CAUSED THE AIRCRAFT TO ROTATE ABOUT THE NOSE LANDING GEAR, IN A FORWARD MOTION, COMING TO REST IN AN INVERTED POSITION.  PILOT EXITED AIRCRAFT WITHOUT SERIOUS INJURY.  PARTIAL DISASSEMBLY OF THE AIRCRAFT ENGINE REVEALED THAT SEVERAL TEETH WERE BROKEN OFF FROM BOTH THE CRANKSHAFT GEAR AND THE CAMSHAFT DRIVE GEAR.  THIS FAILURE PREVENTED THE PROPER OPERATION OF THE VALVE TRAIN WHICH CAUSED THE ENGINE TO STOP FUNCTIONING.
