The pilot landed the tailwheel-equipped airplane with a crosswind, and during the landing rollout the airplane veered to the right. The pilot's attempts to correct the veer by applying left rudder pedal and left brake were unsuccessful. The airplane exited the right side of the runway, ground looped, and the left main landing gear collapsed resulting in substantial damage to the fuselage. A postaccident examination of the airplane revealed that the tailwheel assembly, tailwheel steering arm, and rudder stops were all in working condition. However, when combined together, the resulting configuration allowed the tailwheel to unlock and fully swivel 15 degrees prior to the rudder reaching full travel in either direction. Subsequently, when the airplane slowed to an airspeed at which the rudder was no longer effective and rudder input was added to correct for the crosswind, the tailwheel disengaged, resulting in the runway excursion.
Probable Cause: The failure of the tailwheel to remain locked during a crosswind landing, which resulted in a loss of directional control.
