Probable cause

The engine oil filter vibrating loose resulting in oil starvation, and the pilot in command's misjudgment of winds. A factor contributing to the accident was unfavorable winds.

Sequence of events

NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.

Analysis

While established in cruise at 4000 feet the pilot heard a peculiar sound and observed decreasing engine RPM. As the RPM continued to decrease to 1200 the pilot secured the engine via the ignition and initiated a forced landing to a field alongside an interstate highway. During his approach to the north he found his ground speed to be excessive and attempted a 180 degree turn during which time the left wingtip impacted the ground. Subsequent examination of the ford V6 engine revealed that the oil filter/ cooler had vibrated loose allowing the engine oil to leak overboard.
