He added that he attempted to level the wings, but he "did not have enough aileron." Subsequently, the airplane impacted terrain in a nose-low, right-wing-down attitude. The fuselage and both wings sustained substantial damage. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation. The pilot reported that the temperature was 85°, the sky was clear, and the wind was from 200° at 5 knots and not gusting. He took off from runway 23. An automated weather observation station, about 14 nautical miles from the accident airport, recorded wind from 170° at 9 knots, gusting to 20 knots. ## Factual narrative The pilot reported that, during takeoff from a private turf airstrip, about 50 ft. above ground, the airplane encountered a gust of wind that "quickly" lifted the left wing and pushed the airplane to the right.
