Narrative:On December 9, 1997, at 1106 hours Pacific standard time, a Stephen B. Johnson, Bushrod, N6232F, operated by the pilot, experienced a loss of control approaching the Corona Municipal Airport, Corona, California. The experimental airplane was destroyed, and the airline transport certificated pilot was seriously injured. Two unoccupied parked airplanes were also damaged during the collision. Visual meteorological conditions prevailed at the time, and no flight plan was filed. The flight originated from Corona about 1045.
The pilot indicated to the Federal Aviation Administration coordinator that the purpose of the test flight was, in part, to explore the airplane's operating envelope. The first approach and intentional go-around to runway 25 was accomplished without using the flaps, and no anomalies were reported. Full flaps were used during the second approach. The pilot reported that after the flaps were extended the airplane entered a left turn which he could not stop despite his flight control inputs, and the airplane descended. The accident occurred during the 7th hour of the flight test program. The pilot reported no 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.
