THE NOSE GEAR AND LEFT MAIN GEAR SEPARATED FROM THE ACFT WHEN IT STRUCK THE FENCE. THE ACFT THEN TRAVELED A SHORT DISTANCE BEFORE STRIKING THE GROUND IN A FLAT ATTITUDE. THE NUMBER THREE PISTON, CONNECTING ROD, AND CAP HAD SEPARATED IN FLIGHT. A TOP OVERHAUL HAD BEEN PERFORMED ON THE ENGINE 11 MONTHS (163 FLIGHT HOURS) PRIOR TO THE ACCIDENT.
