Event Description
A pilot reported that during cruise flight at an altitude of 4,500 feet mean sea level, the annunciator lights in the cockpit began blinking and then became solid. Subsequently, the oil pressure gauge indicated no oil pressure. The engine then lost power, prompting the pilot to choose to land at the nearest airport.
Landing and Impact
The airplane touched down halfway along a 2,600-foot runway that had high obstructions at the approach end. The pilot was unable to bring the airplane to a stop on the remaining runway. The aircraft skidded across grass covered with heavy dew and subsequently impacted the back porch of a mobile home.
Engine Examination
Post-accident examination of the engine revealed that it was depleted of oil. A teardown inspection disclosed that both compression rings on the number two cylinder were fractured into several pieces. Additionally, the camshaft was engraved with the phrase "NOT A CERTIFIED PART." All eight rod bolt nuts were found installed upside down.
Maintenance Records
Engine records indicated that the last engine overhaul occurred on July 5, 1992.
