Incident Summary
The pilot was informed of smoke trailing from the aircraft during climb out. Despite this, the pilot elected to continue the climb due to instrument meteorological conditions (IMC) at the departure airport, with the intention of diverting to another airport located 26 nautical miles north. The climb was continued to 4,500 feet mean sea level (MSL) to reach visual meteorological conditions (VMC).
During the climb, the oil warning light illuminated. The pilot then requested radar vectors to another airport and to VMC. Approximately 20 nautical miles south of the destination airport, while descending in VMC, the engine oil pressure gauge indicated zero. Subsequently, the engine seized, and the pilot performed a forced landing in a field.
Landing and Post-Landing Observations
During the landing roll, the left landing gear was severed, and the left wing was damaged. After the aircraft came to rest, oil was observed on top of the engine cowling and on the aircraft fuselage.
Engine Examination
Examination of the engine revealed that the engine case had fractured above the number 6 cylinder. All oil fittings were examined for proper security and tightness and were pressure checked. No indications of leakage or blockage were found.
