The pilot noted there was an approximate 10-knot crosswind. During the landing roll, the airplane veered right and continued off the runway surface. The airplane ground looped which resulted in the collapse of the landing gear. As a result of the impact, the airplane incurred substantial damage to the wings. The pilot reported no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation. ## Factual narrative The pilot reported that after returning back from an approximate 45-minute local flight, he aligned the tailwheel equipped bi-plane for a landing on the active runway.

Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong.
