## Analysis

WHILE EN ROUTE AT 10,000 FT MSL, THE #3 CYLINDER, PISTON & ROD SEPARATED FROM THE ENG & DEPARTED THRU THE COWLING. THE PLT SAID THAT ALTHOUGH THE OIL LEFT THE ENG RAPIDLY, HE WAS ABLE TO MAINTAIN PARTIAL POWER FOR APRX 12 MINS. DURING THAT TIME, HE WAS ABLE TO FIND A SEMI-CIRCLED AREA FOR AN EMERGENCY LANDING. DURING THE LANDING, THE NOSE & LEFT MAIN GEAR COLLAPSED WHEN THE ACFT HIT A STUMP & A LOG. THE PISTON, ROD & CYLINDER WERE NOT RECOVERED, THUS THE CYCLE OF EVENTS THAT LED TO THE FAILURE WAS NOT VERIFIED. IT WAS NOTED THAT ONE OF THE ROD END CAP BOLTS WAS STILL IN THE CAP, BUT ITS ASSOCIATED NUT WAS MISSING. THE OTHER BOLT HAD FAILED FROM TENSILE OVERLOAD. THE ENG HAD ACCUMULATED 1107 HRS SINCE A MAJOR OVERHAUL.
