Aircraft involved
Probable cause & findings
The pilot's failure to maintain directional control during the landing roll, which resulted in a ground loop.
Factual narrative
The pilot of the tailwheel-equipped bi-plane reported that during the landing roll, the bi-plane started turning to the right, the left main landing gear collapsed, and the nose of the bi-plane impacted the ground. The bi-plane sustained substantial damage to the left lower wing. According to the pilot there were no preimpact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation.
