THE PILOT (OR PILOT-RATED PASSENGER) REPORTED AN 'INDICATION' PROBLEM & SAID THEY INTENDED TO LAND AT OKEECHOBEE, BUT COULDN'T FIND THE AIRPORT. THEY THEN REPORTED ENGINE TROUBLE & SAID THAT THEY WOULD TRY TO LAND ON A ROAD. THEY CIRCLED THE AREA & APPROACHED A DIRT ROAD WITH LANDING LIGHTS ON. A CAR WAS PROCEEDING ON THE ROAD IN THE OPPOSITE DIRECTION. THE PLANE BEGAN TO CLIMB, & IT ENTERED A LEFT TURN. IT THEN ROLLED INTO A STEEP RIGHT BANK, DESCENDED NOSE DOWN, CRASHED & WAS CONSUMED BY FIRE. AN EXAM REVEALED INDICATIONS THAT BOTH ENGINES WERE OPERATING AT HIGH RPM. A TEARDOWN REVEALED A RIGHT ENGINE FUEL CONTROL BEARING HAD FAILED, WHICH WOULD HAVE ALLOWED IMPROPER MOVEMENT OF THE FUEL CONTROL DRIVE SHAFT. THE PLANE WAS LAST INSPECTED ON 11/25/92 & WAS 13 HRS OVER A REQUIRED 150 HR INSPECTION. A SERVICE BULLETIN FOR MAINTENANCE OF THE FUEL CONTROL BEARINGS HAD NOT BEEN COMPLIED WITH. THE OWNER/PILOT HAD NOT COMPLETED FORMAL GROUND SCHOOL INSTRUCTION ON THE AIRPLANE SYSTEMS & OPERATION. THE PLANE HAD 9 SEATS; 10 OCCUPANTS WERE ABOARD.
Probable Cause: THE PILOT'S IMPROPER REMEDIAL ACTION CONCERNING A RIGHT ENGINE POWER ANOMALY, AND HIS FAILURE TO MAINTAIN ADEQUATE AIRSPEED DURING GO-AROUND FROM AN ABORTED PRECAUTIONARY LANDING, WHICH RESULTED IN A LOSS OF AIRCRAFT CONTROL AND AN UNCONTROLLED DESCENT. FACTORS RELATED TO THE ACCIDENT WERE: FAILURE OF THE OWNER/OPERATOR/PILOT TO ASSURE PROPER MAINTENANCE INSPECTION OF THE AIRCRAFT, FAILURE TO COMPLY WITH A SERVICE BULLETIN CONCERNING THE ENGINE FUEL CONTROLS, SUBSEQUENT BEARING FAILURE IN THE RIGHT ENGINE FUEL CONTROL, AND THE PILOT'S LACK OF FAMILIARITY WITH THIS MAKE AND MODEL OF AIRCRAFT.
