The NTSB's narrative final · quoted from the NTSB record
The pilot stated that, while en route, he noticed a loss of oil pressure. A short time later, the airplane's engine failed, and the pilot executed a forced landing in a field. During the landing roll, the airplane struck trees at the end of the field. The airplane had just had maintenance performed which included an oil change and installation of a newly overhauled propeller and propeller governor. Post accident examination of the aircraft revealed damage to the lower fuselage substructure in the area near the cabin door opening. Oil was found inside the engine compartment and on the exterior surfaces of the fuselage.
