Incident Overview
A private pilot experienced an engine oil leak during flight, which resulted in smoke entering the cockpit and a gradual decay of oil pressure. In response, the pilot shut down the engine and attempted an emergency landing on a local desert airstrip.
Landing and Post-Accident Findings
The aircraft touched down approximately 50 feet short of the intended airstrip. During the landing rollout, it contacted several large bushes. The subsequent postaccident investigation identified the cause of the oil leak: the oil supply hose connecting the oil cooler to the engine had ruptured.
Mechanical Condition
Examination of the ruptured hose revealed signs of age and heat deterioration. The hose had not been replaced during a recent engine change, despite its apparent degraded condition. The investigation did not specify the aircraft type, registration, date, operator, or precise location, nor did it mention any occupant injuries or fatalities.
Conclusion
The incident was attributed to the failure of the oil supply hose, which had become brittle and heat-damaged over time and was not renewed when the engine was replaced.
