What happened
The pilot/owner was returning from a flight in the high-performance amateur-built airplane, which he had flown about 2 hours previously. Witnesses reported that the airplane appeared slow and in a nose-high attitude while flying in the airport traffic pattern. The airplane was configured with the landing gear extended and full-flaps when the pilot initiated a turn to the left base leg of the traffic pattern. The airplane subsequently descended uncontrolled, collided with trees, impacted the ground, and was consumed by a postcrash fire. A postaccident examination of the airframe and engine revealed no evidence of mechanical malfunctions or failures that would have precluded normal operation. Evidence suggested that the engine was operating at a high power setting at the time of the impact and, due to the airplane’s slow speed and nose-high attitude, it likely entered an aerodynamic stall as it turned to the base leg of the traffic pattern.
