## Analysis

THE PIC WAS FERRYING THE NAVION TO A DISTANT LOCATION TO UNDERGO AN ANNUAL INSP. ABT 20 MIN INTO THE FLT, THE PIC RPTD EXPERIENCING ENG PBLMS. THE PIC WAS ABLE TO FLY TO A NEARBY ARPT FOR A PRECAUTIONARY LNDG. INSTEAD OF MAKING THE LNDG THE PIC WENT AROUND TO GAIN A BETTER ANGLE FOR THE LNDG. WHILE IN THE PATTERN, THE PIC FELT THAT THE ROUGH RUNNING ENG WOULD NOT ALLOW THE ACFT TO REACH THE ARPT AND HE INTENTIONALLY STALLED THE ACFT INTO TREES SHORT OF THE RWY. A SUBSEQUENT INSP OF THE ACFT REVEALED THAT THE ENG CARB WAS LEAKING FUEL. EACH TIME THE PIC ADVANCED THE THROTTLE, FUEL LEAKED FM THE CARB RESULTING IN A DEGRADATION OF AVAILABLE ENG PWR. THE PLT WAS NOT RATED AND POSSESSED NO MEDICAL CERTIFICATE.
