Aircraft involved

Probable cause & findings

The pilot’s failure to maintain directional control of the airplane during the landing roll with a crosswind, which resulted in a runway excursion and subsequent collision with runway signage.

Factual narrative

The pilot in the tailwheel-equipped biplane reported that, during the landing roll with a crosswind from the left, the airplane veered to the left, exited the left side of the runway and collided with runway signage. The pilot regained directional control of the airplane and taxied to parking. The airplane sustained substantial damage to the bottom left-wing ribs. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
