PIC STATED HE SPENT ANOTHER 1.5HRS ON THE GROUND WITH THE AIRCRAFT, AFTER WHICH HE DEPARTED FOR MORE AERIAL SURVEY.

THE PIC TURNED ON CARBURETOR HEAT, RICHENED THE MIXTURE, AND PERFORMED THE ENGINE-TROUBLESHOOT CHECKLIST. THE PIC WAS UNABLE TO RESTART THE ENGINE. THE PIC WAS ABLE TO RELAY HIS POSITION AND EMERGENCY STATUS TO ANOTHER AIRCRAFT OVER THE RADIO. THE PIC CHOSE A LANDING SPOT AND WAS ABLE TO MANEUVER THE AIRCRAFT TO THE INTENDED POINT OF LANDING. THE PIC LOWERED FLAPS FOR LANDING AND MOVED THE MIXTURE TO IDLE-CUT-OFF PRIOR TO TOUCHDOWN. THE PIC REPORTED THE AIRCRAFT BOUNCED ONCE AND HE WAS ABLE TO FLARE IT TO A SOFT TOUCHDOWN AFTER THE BOUNCE. THE AIRCRAFT CAME TO REST IN WATERLOGGED TUNDRA/SWAMP UPRIGHT WITH MINIMAL DAMAGE. THE PIC AND HIS PASSENGER WERE NOT INJURED. THE FUEL TANKS SHOWED APPROXIMATELY 1/2 FULL AFTER THE LANDING. PRELIMINARY INVESTIGATION HAS REVEALED NO APPARENT CAUSE. THE COMPANY SENT THE ENGINE FOR TEARDOWN AND INSPECTION. ENGINE TEARDOWN REVEALED THE CRANKSHAFT HAD PARTIALLY MELTED THE CRANKSHAFT MAIN BEARINGS AND THERE WAS SCORING PRESENT ON THE CRANKSHAFT. CONNECTING ROD BEARINGS SHOWED ABNORMAL WEAR. THE ENGINE PRESUMABLY LOST POWER DUE TO METAL EXPANSION AS THE ENGINE HEATED UP AND THE DAMAGE IMPEDED THE ENGINE FROM TURNING.
