Belle Chase, LA, USA

CESSNA 180H
On downwind, the pilot noticed that the wind had increased and that there was light turbulence. He planned to land beyond some trees to avoid turbulence. The airplane encountered a wind gust during the landing roll. The pilot applied rudder and aileron corrections along with heavy braking. The airplane exited the runway and impacted a pipe rack resulting in substantial damage to the left wing. A postaccident examination of the airplane revealed that a tailwheel spring was bent, and its spring rate was weak, which allowed the tailwheel's fork to caster freely by not engaging into its machined locking detent.
