The airplane continued across the adjoining taxiway and then came to a stop. The airplane sustained substantial damage to the left main landing gear attachment points. The pilot reported that there were no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation. The pilot reported that the wind at the time of the landing was from 350° at 12 knots, gusting to 19 knots. The pilot landed the airplane on runway 25R. ## Factual narrative The pilot reported that during landing in a gusting tailwind from the right, the airplane touched down, exited the left side of the runway, and collided with runway lights and taxiway signage.
