Read the full NTSB narrative

SHORTLY AFTER TAKEOFF, THE ENGINE LOST PARTIAL POWER AND THE PILOT NOTED THAT OIL PRESSURE HAD DROPPED TO O. THE PILOT TURNED AROUND TO RETURN TO THE AIRPORT; HOWEVER, EN ROUTE, THE ENGINE LOST POWER AND A FORCED LANDING WAS MADE IN A WHEAT FIELD. DURING THE LANDING ROLL, THE AIRPLANE NOSED OVER. DURING THE POST CRASH INSPECTION, IT WAS FOUND THAT THE OIL GASKET WAS CREASED OR FOLDED OVER APPROXIMATELY HALF WAY AROUND THE OUTER EDGE AND A SMALL NOTCH OF THE RUBBER WAS MISSING FROM THE OUTER EDGE. THE FILTER AND OIL HAD JUST BEEN CHANGED ON THE AIRPLANE AND THIS WAS THE FIRST FLIGHT AFTER THAT MAINTENANCE.
