## Narrative

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

ON THE THIRD FLIGHT OF THE DAY, THE PILOT PERFORMED A PREFLIGHT INSPECTION AND BEFORE TAKEOFF RUNUP.  THE PILOT STATED TAKEOFF ACCELERATION WAS NORMAL WITH 10 DEGREES OF FLAPS.

UPON ROTATION AND FLAP RETRACTION, THE PILOT NOTICED A PERFORMANCE DEGRADATION.  10 DEGREES OF FLAPS WERE AGAIN SELECTED; HOWEVER, ALTITUDE COULD NOT BE MAINTAINED EVEN WITH THE ENGINE APPEARING TO DEVELOP NORMAL RPM.  THE PILOT DECIDED TO PERFORM AN EMERGENCY LANDING IN A PASTURE AND HIT A FENCE DURING LANDING.

INVESTIGATION REVEALED THE REAR EXHAUST MUFFLER WAS APPROXIMATELY 90 % RESTRICTED DUE TO INTERNAL FLAME TUBE FAILURE.
