On February 1, 2001, at 1934 hours mountain standard time, an amateur-built experimental Arthur Dragonfly, N29KK, lost engine power and made an emergency forced landing southeast of Marana, Arizona. During the landing, the aircraft encountered rough terrain. The airplane sustained substantial damage, and the certificated private pilot, the sole occupant, received only minor injuries. The airplane was being operated by the pilot/owner as a personal flight under 14 CFR Part 91 when the accident occurred. The local flight originated from the Marana Northwest Regional Airport about 1910. Visual meteorological conditions prevailed at the time and no flight plan had been filed. The pilot told Safety Board investigators that he had been in cruise flight at 4,000 feet mean sea level when the engine quit. He said that he verified that the electric fuel pump switch was in the "on" position. He then moved the fuel mixture control to the "full rich" position and engaged the starter. After his unsuccessful attempts to start the engine, he made an emergency forced landing in open desert terrain. During the forced landing, the forward canard was damaged.
