NTSB summary
HISTORY OF FLIGHT On April 24, 2009, about 1337 central daylight time, an experimental amateur-built MK-1, N91MK, was substantially damaged following an unintentional takeoff during a high-speed ground test at Demopolis Municipal Airport (DYA), Demopolis, Alabama. The pilot/owner was fatally injured. The accident flight was the first flight of the airplane, which was operated under the provisions of Title 14 Code of Federal Regulations Part 91. Visual meteorological conditions prevailed, and no flight plan was filed. The engine was not equipped with a starter, and therefore had to be hand-propped to start it. On the day of the accident, the pilot sat in the airplane, while an acquaintance hand-propped the engine. The engine idled for a brief time before it stalled. The pilot then exited the airplane, and hand-propped the engine himself, while the acquaintance kept the airplane from moving by holding onto the tail. After the engine started, the pilot re-boarded the airplane, and closed the canopy. The acquaintance notified the pilot that a seat belt was protruding from the cockpit, and the pilot re-opened the canopy to secure the seat belt. He then informed the acquaintance that he would return shortly, since he was only planning to conduct some high-speed ground runs on the runway. The pilot made one successful high speed ground run on runway 22, and taxied back for a second run.

Probable cause
The pilot's failure to maintain adequate airspeed following a complete loss of engine power resulting in a stall while maneuvering to land. The reason for the loss of engine power was undetermined.
