The NTSB's narrative final · quoted from the NTSB record

The pilot stated that he had landed earlier on a plowed runway with hard-packed snow and ice surface conditions. He believed that while taxiing for turnaround at the end of the runway, the right-hand brake apparently became hydraulically locked due to engagement of the parking brake mechanism on that side. He stated that at no time was the parking brake handle pulled. He said his takeoff on the icy runway seemed normal, and he was completely unaware of the locked condition of the brake at that time. Upon touchdown at Hailey, the airplane immediately veered violently to the right and the brake remained locked. The airplane swerved to the right before nosing over. Investigation determined that the parking brake locking lever on the right brake cylinder was in its overcenter position, locking the brake.
