Aircraft involved

Probable cause & findings

The pilot's failure to maintain directional control during the landing roll, resulting in a ground-loop, and substantial damage to the right wing and wing strut.

Factual narrative

According to the pilot of the tailwheel-equipped biplane, during the fourth landing roll of the day, the airplane "fish tailed" to the right and he was not able to maintain directional control. The airplane ground looped to the left on the runway, the right main landing gear collapsed and the lower right wing struck the ground. The airplane sustained substantial damage to the lower right wing and wing strut. The pilot reported that there were no mechanical failures or anomalies prior to or during the flight that would have prevented normal operation.
