The pilot/owner was operating the airplane under the provisions of 14 CFR Part 91. The private pilot, the sole occupant, sustained serious injuries; the airplane sustained substantial damage. The personal cross-country flight departed Chino, California, at an undetermined time en route to Parker. Day visual meteorological conditions prevailed, and no flight plan had been filed. A witness stated that the airplane attempted to land, but appeared to land long. The airplane was near the end of the runway before the pilot attempted to go around. The witness said the engine did not sound like it was running smoothly. The airframe sustained substantial damage during a subsequent ground collision about 1.5 miles from the airport.
