The pilot reported that this was the fourth flight of the airplane’s phase one flight testing. About 2 hours into the flight (with an airplane total time of 6 hours), the pilot observed the oil pressure reduce rapidly to about 5 pounds per square inch. He did not notice any other problems with the airplane or engine, but he declared an emergency and requested a direct approach to a nearby airport. Within 5 minutes, the engine lost all oil pressure and the engine lost power. The airplane was unable to reach any available airstrips; therefore, the pilot turned toward a winding dirt road on top of a ridge. While maneuvering to avoid obstacles at a trailhead, the airplane hit a steep embankment and sustained substantial damage to the fuselage and wings. During a postaccident examination, an oil line near the oil filter was found to be disconnected, most likely due to insufficient tightening of the fitting, which led to its loosening during cruise flight. The loosened fitting allowed oil to spray into the cowling and exit out the lower nose area. The pilot stated that there were no indications of oil leakage during the preflight inspection.
Probable Cause: A loss of engine power due to oil starvation as a result of a disconnected oil line. Contributing to the accident was an insufficiently tightened oil line fitting.
