Probable cause

The pilot's loss of directional control during landing resulting from binding of the left wheel's brake actuating system for an undetermined reason.

NTSB narrative

The pilot reported that he made a normal landing on the runway. During rollout, he felt a vibration coming from the landing gear. When he exited the runway, the airplane turned abruptly to the left, as if the left brake had locked up. The uncommanded sharp left turn resulted in the airplane exiting the pavement and impacting a cement culvert. The examination of the runway revealed witness marks consistent with a locked left wheel brake. An examination of the airplane's left wheel assembly revealed that the tire rotated freely. No external evidence of brake failure was found. The reason for the intermittent anomaly associated with the brake assembly or cylinder was not determined.
