The homebuilt airplane was observed performing a low pass to the runway. At the conclusion of the low pass, the airplane began a climbing left turn. As the airplane gained altitude it began to slow down according to witnesses. At an estimated altitude of 300 to 400 feet above the ground the airplane rolled to the right, performing a half turn spin before colliding with the ground. The on scene investigation revealed no mechanical discrepancies with the airframe or power plant. The airplane's engine rotated opposite the normal U.S. certified airplane engines. During the investigation it was revealed the pilot did not have experience in the airplane. An eye witness stated he had spoken with the pilot before the accident flight and advised him to obtain some dual instruction before flying the airplane solo; or at least do some touch and go's before going anywhere in the airplane. The pilot's logbook revealed he had no time logged in the make and model airplane.
