Amateur-built HATZ CB1 N39761 accident near Hysham, Montana

Probable cause

The pilot's failure to maintain directional control during the landing roll with a crosswind, which resulted in a ground loop.

NTSB analysis

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. 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.
