Following A Momentary Wind Shift, The Airplane Lost More Altitude And It Struck The Tops Of Trees Analysis: The pilot reported being on the downwind leg of the airport traffic pattern when a 16 to 24-knot tailwind pushed the airplane further from the runway than he had planned. While on final approach, the airplane was low with a headwind. Following a momentary wind shift, the airplane lost more altitude and it struck the tops of trees resulting in substantial damage to the left wing. Despite the impact, the pilot was able to clear the trees and land safely on the runway. The pilot also reported that there were no preimpact mechanical malfunctions with the airplane that would have precluded normal operation.
