The pilot reported that he was flying a visual approach for landing when, at 200 ft above ground level (agl), he encountered a “microburst.” The right wing rose about 30° and the airplane turned to the left. He corrected with right aileron and rudder control inputs; however, the airplane continued to the left. When he finally was able to regain control the airplane, he was left of the runway at 50 ft agl. He elected to land in an open field adjacent to the runway. After touchdown, a tailwind increased his ground speed to about 50 kts and the right wing collided with a fence as he attempted to decelerate. The airplane’s right wing was substantially damaged. No evidence of a preexisting mechanical malfunction or failure was found during the postaccident examination of the wreckage, and no mechanical anomalies were reported by the pilot.
