Incident Overview
A pilot flying a single-engine aircraft without cargo from Tulsa, Oklahoma, to Kansas City, Missouri, experienced a drop in oil pressure during the flight. The pilot diverted to Johnson County Airport in Olathe, Kansas, after the oil pressure gauge fell below the green arc approximately 75 miles from the intended destination.
Sequence of Events
During the approach to land, the aircraft was high and fast. The pilot extended the landing gear and flaps to reduce speed. As the aircraft crossed the approach end of the runway, the engine ceased operation. Subsequently, the aircraft stalled and landed hard, causing the nose landing gear to collapse. The pilot reported being apprehensive about landing on the snow- and ice-covered runway under the circumstances.
Investigation Findings
An investigation revealed that only 4 quarts of oil remained in the 12-quart oil system. No evidence of an oil leak was found. During an operational check after the incident, the engine ran normally and oil pressure readings were within the normal range.
