## Analysis

THE HOMEBUILT ACFT COLLIDED WITH A DITCH DURING A FORCED LNDG SHORT OF THE RWY AFTER A POWER LOSS DURING A TEST FLT. THE PLT HAD NOTED SMOKE IN THE COCKPIT AND A LOSS OF OIL PRESSURE. AS HE RETURNED TO THE ARPT THE ENG BEGAN TO RUN ROUGH AND SURGE BEFORE QUITTING. DURING THE LNDG THE LNDG GEAR SEPARATED FROM THE ACFT. DURING ENG EXAM THE CRANKCASE BREATHER TUBE WAS KINKED AND THE OIL SUMP WAS EMPTY OF OIL. THE ENG TURNED FREELY WITH COMPRESSION ON ALL CYLINDERS. NO SIGN OF MECHANICAL FAILURE WAS NOTED. THE LOWER SECTION OF THE ENG WAS COVERED WITH OIL FROM OIL BEING PUMPED OVERBOARD THRU A SEPARATED CRANKCASE OIL SEAL.
