## Analysis

THE ACFT WAS CRUISING AT 5,500 FT WHEN THE PLT EXPERIENCED A TOTAL LOSS OF POWER. HE TRIED TO MAKE IT TO THE WELLSBORO ARPT, HOWEVER, HE WAS UNABLE TO AND LANDED THE ACFT IN A FIELD. THE ACFT RAN THROUGH A FENCE AND WAS SUBSTANTIALLY DAMAGED. WHEN THE ENGINE WAS TORN DOWN, IT WAS NOTED THAT THE CRANKSHAFT HAD BROKEN BETWEEN THE #2 ROD BEARING JOURNAL AND THE #2 MAIN BEARING JOURNAL. ALSO DURING THE ENGINE INSPECTION IT WAS NOTED THAT THE ENGINE DID HAVE OIL, BUT METAL PARTICLES WERE PRESENT ON BOTH THE OIL SCREEN AND IN THE OIL.
