Aircraft involved

Probable cause & findings

The pilot's failure to maintain directional control during the landing roll with a gusting tailwind, which resulted in a runway excursion and collision with runway lights and taxiway signage.

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. 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 the wind at the time of the landing was from 350° at 12 knots, and gusting to 19 knots. The pilot landed the airplane on runway 25R. The pilot reported that there were no mechanical malfunctions or failures with the airplane that would have precluded normal operation. The pilot reported that, during landing with a gusting, right tailwind, the airplane touched down, exited the left side of the runway, and collided with runway lights and taxiway signage. 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.
