## Analysis

AFTER LEVELING AT 2500 FT, OIL FUMES WERE NOTED, BUT NO ABNORMAL INDICATIONS WERE NOTED ON THE ENGINE GAUGES. THE PILOT SUSPECTED OIL HAD BEEN SPILLED DURING A REPAIR BEFORE TAKEOFF. A SHORT TIME LATER, THE ENGINE RPM BEGAN TO INCREASE & WAS ADJUSTED BY THE PILOT. SUBSEQUENTLY, THE ENGINE FAILED. DURING A FORCED LANDING, THE PILOT WAS UNABLE TO REACH A ROAD & LANDED IN A FIELD. THE MAIN GEAR FAILED AFTER HITTING A DITCH. THE RIGHT WING WAS DAMAGED AFTER CONTACTING THE GROUND & THE LEFT WING HIT A FENCE. AN EXAMINATION REVEALED THERE WAS OIL ALONG THE LEFT SIDE OF THE FUSELAGE. A HOLE WAS FOUND IN THE ENGINE CASE BETWEEN THE NUMBER 2 & 4 CYLINDERS. THE INLET OIL LINE TO THE OIL COOLER HAD CHAFED AGAINST THE EXHAUST STACK & WAS LEAKING. IT SHOULD HAVE BEEN ROUTED UNDER A HEAT SHIELD & AWAY FROM THE EXHAUST STACK. THE OIL LINE SHOULD HAVE BEEN A STANDARD, MEDIUM PRESSURE, STRATOFLEX HOSE (MIL-H-8794D) REINFORCED WITH A FIBER BRAIDS & A STEEL BRAID. THE INSTALLED HOSE HAD A SINGLE FIBER BRAID COVERING.
