N2031S
Kolb MK III
A witness to portions of the accident sequence observed the airplane perform several touch-and-go takeoffs and landings. On the accident portion of the flight, he saw the airplane takeoff to the west, and then he turned away. He then heard the engine "revving" followed by silence. When he turned back, he saw that the airplane had impacted the ground in a steep nose down attitude. The two-seat experimental light sport airplane came to rest about 200 yards north of the departure end of the runway. The airplane's wings, cockpit, and tail section were all structurally damaged. FAA inspectors examined the wreckage and noted no mechanical problems with the airframe or engine. They further opined that the airplane appeared to have stalled and spun to the ground.
HISTORY OF FLIGHT On November 13, 2006, about 0920 mountain standard time, an experimental light sport Kolb MK III, N2031S, impacted flat desert terrain in a nose down attitude about 200 yards north of Pilots Rest Airport (AZ57), Paulden, Arizona. The newly certificated light sport pilot/owner and the private pilot passenger were fatally injured. The airplane was destroyed. Visual meteorological conditions prevailed for the local area flight, and no flight plan had been filed. A friend of the pilot was a partial eyewitness. A deputy from Yavapai County Sheriff's Department interviewed the friend. He stated that he watched the airplane as it did touch-and-go takeoffs and landings. He then saw the airplane takeoff to the west, and turned away. He then heard a loud revving noise followed by silence. When he looked back toward the west, he observed the downed airplane. Federal Aviation Administration (FAA) inspectors responded to the accident site and examined the airplane. They found no mechanical anomalies with the airframe or engine. According to the FAA inspector, it appeared the airplane stalled and spun to the ground.

MEDICAL AND PATHOLOGICAL INFORMATION The Yavapai County Office of the Medical Examiner performed the autopsies of both pilot's on November 14, 2006. Pilot 1 The FAA Forensic Toxicology Research Team (CAMI), Oklahoma City, Oklahoma, performed a toxicological analysis from samples obtained during the autopsy. The results of the analysis of the specimens were negative for carbon monoxide, cyanide, volatiles, and tested drugs. Pilot 2 The FAA Forensic Toxicology Research Team (CAMI), performed a toxicological analysis from samples obtained during the autopsy. The results of the analysis of the specimens were negative for volatiles, and tested drugs. The blood samples submitted by the Yavapai County Medical Examiner for carbon monoxide and cyanide testing were not stable, and the tests were not performed.
failure of the pilot to maintain an adequate airspeed that led to a stall/spin.
