Aircraft
During landing rollout the aircraft pulled hard to the right. It appeared to have the right brake locked up. Efforts to arrest the right turn with left rudder inputs proved ineffective. It veered off the runway to the right side at about 20 to 30 mph. After traveling through the grass for about 50 to 70 feet the left main gear collapsed. The aircraft came to rest on the right main gear; the tailwheel and the left lower wing tip. There appears to be no damage other than to the left main gear. A tire skid mark from near the runway centerline to the runway edge follows the path the right main gear traveled. No tire marks were observed on the runway which would have matched the path of the left main gear.
A Pitts Special pilot was unable to prevent a runway excursion when the right brake apparently locked up on the landing roll. The left main gear collapsed when the aircraft came to a halt off the runway.
