## Analysis

THE ACFT HIT A TREE AND A DITCH DURING A FORCED LANDING ON A ROAD AFTER THE ENGINE LOST POWER. EXAMINATION OF THE ENGINEAFTER THE ACCIDENT REVEALED THAT THE THROTTLE ROD HAD DISCONNECTED FROM THE THROTTLE CONTROL ARM AT THE BOLT HOLE. THE HOLE HAD WORN THROUGH AND THE ROD HAD VIBRATED LOOSE. THE ACFT HAD A 100 HOUR INSPECTION ONLY 22 HOURS PRIOR TO THE ACCIDENT. THE WORN SURFACES HAD TAKEN LONGER THAN 22 HOURS TO REACH THEIR DEGREE OF WEAR. ALSO, THE THROTTLE CABLE HAD BEEN REPLACED AT 850 HOURS. THE ACFT NOW HAD 1188 HOURS TOTAL TIME. THE C-206 SERVICE MANUAL INDICATES THAT THE ENGINE CONTROLS AND LINKAGE ARE TO BE INSPECTED EVERY 100 HOURS. THE ENGINE WAS SUCCESSFULLY RUN AFTER INSTALLING A NEW THROTTLE ARM AND REPAIRING IMPACT DAMAGE.
