NTSB Narrative Summary Released at Completion of Accident

On June 28, 2014, about 0922 mountain daylight time, an unregistered experimental amateur-built SkyRaider collided with terrain near Lewiston, Idaho. The pilot/owner was operating the airplane under the provisions of 14 Code of Federal Regulations (CFR) Part 91. The private pilot sustained fatal injuries. The airplane sustained substantial damage during the accident sequence. The local personal flight departed Williams Airpark near Lewiston about 0900. Visual meteorological conditions (VMC) prevailed, and no flight plan had been filed. According to witnesses, the pilot was attempting to land. They thought that he may have been experiencing engine problems, as they didn't hear engine sound prior to the airplane entering a steep nose down attitude into a nearby wheat field.
