He requested to land on a taxiway next to runway 29L. The air traffic control tower controller cleared the airplane to land on the taxiway; however, the pilot landed the airplane in the grass next to the taxiway. The pilot reported that during the landing roll, a gust of wind lifted the right wing. He did not have enough control authority to correct the elevated wing and the airplane nosed-over. The Federal Aviation Administration inspector examined the airplane and noted that the rear spar on the right wing was broken. At the time of the landing, the winds were reported from 350 at 22 knots, gusting to 30 knots. ## Factual narrative The pilot was landing at an airport.
