A witness observed the private pilot departing in his experimental, amateur-built airplane. He stated that, after rotation, the airplane climbed in a nose-high attitude and drifted left of the runway centerline. Upon reaching an altitude about 1,000 ft above ground level, the airplane’s right wing dipped, and the airplane descended in a right spin and impacted a parallel taxiway. The airplane was mostly consumed by a postcrash fire. Subsequent examination revealed that the canopy had been ejected clear of the airframe on impact, and the canopy lock appeared in the open position. The elevator trim tab was found in the nose-up trim position; however, due to the severity of the fire and impact damage, the reason for or relevance of these findings could not be determined.
Although the pilot was being treated for several medical conditions that he had not reported to the Federal Aviation Administration, it is unlikely that the conditions or their treatment contributed to the circumstances of this accident.
Probable Cause: The pilot's failure to maintain adequate airspeed and his exceedance of the airplane's critical angle of attack during the climb, which resulted in an aerodynamic stall/spin.
