Emergency Landing
While in cruise flight, the pilot detected the smell of smoke and observed a loss of oil pressure. In response, he identified an open field suitable for an emergency landing. Upon arrival over the field, the engine ceased operation, and the pilot executed a forced landing.
Post-Landing Event
During the landing roll, the aircraft's nose gear struck a small pine tree, resulting in the gear being torn off. Subsequently, the aircraft nosed over.
Engine Inspection
A post-accident inspection of the engine revealed that the number three connecting rod had failed and had passed through the crankcase. It was further noted that the oil filler tube was missing, and no oil was present in the crankcase.
