Aircraft Accident/Incident Report
Mason City, Iowa 50401

NTSB Narrative Summary Released at Completion of Accident
During cruise flight the engine oil pressure dropped to zero and the engine began to vibrate. The pilot elected to shut-down the engine and perform a forced landing to a near by soy bean field. During the landing the left main and nose gear collapsed when they came into contact with the soft terrain. Post-accident investigation revealed that the oil filter base-gasket had become extruded from its seat, allowing engine oil to leak out of the engine. Textron Lycoming Engines, Williamsport, Pennsylvania, issued a Mandatory Service Bulletin, number 543A, the day prior to the accident. The service bulletin stated, "Textron Lycoming has received reports indicating that operation at high oil temperatures can cause the converter plate gasket on the oil filter base to become extruded from its seat, allowing oil to leak out between the plate and the accessory housing." The service bulletin called for the removal and replacement of the converter plate gasket at every 50-hour oil change.
NTSB Probable Cause Narrative
the unsuitable terrain for landing encountered by the pilot and the failure of the oil filter converter plate gasket. Factors to the accident were the total loss of oil and the soft terrain condition.
