THE FLIGHT HAD DEPARTED PITTSFIELD EARLIER IN THE DAY ON A CROSS-COUNTRY FLIGHT. AFTER ABOUT 3-1/2 HRS OF FLIGHT, THE PILOT DIVERTED TO BANGOR BECAUSE OF HIGH OIL TEMP AND LOW OIL PRESS INDICATIONS. FOUR QUARTS OF OIL WERE PUT IN THE ENGINE, AND NO MAINTENANCE WAS PERFORMED. NO OIL LEAKS WERE VISIBLE. SOON AFTER TAKEOFF THE ENGINE SEIZED. A FORCED LANDING WAS MADE IN A SOFT FIELD, AND THE AIRPLANE NOSED OVER. EXAMINATION OF THE ENGINE REVEALED THAT THE #4 CONNECTING ROD HAD FRACTURED. NO OIL WAS FOUND IN THE ENGINE, AND THE ENGINE COMPONENTS WERE SEVERELY WORN.
