Narrative:
The pilot took off in the experimental, homebuilt airplane, for a planned series of approaches to explore the airplane's operating envelope. The first approach was performed without use of the wing flaps, and no anomalies were reported. During the next approach, the pilot fully extended the flaps. The airplane entered a left turn which, according to the pilot, could not be stopped. The pilot lost control of the airplane, it descended and collided with two unoccupied airplanes. The accident occurred during the 7th hour of the flight test program. There were no reported mechanical problems.

Probable Cause: An in-flight loss of control resulting from a malfunction in the wing flap operating system. The malfunction produced asymmetrical drag and induced a roll which could not be overcome by the pilot's flight control inputs.
