Incident Overview
A pilot reported that a preflight inspection revealed no abnormalities. During the landing rollout, the right brake failed, causing the airplane to veer to the left and impact a wooden observation deck.
Examination Findings
An examination of the airplane after the incident found a small hole worn into the brake line. The hole was caused by chafing action from the brake line clamp on the landing gear. Hydraulic fluid escaped through this hole, rendering the right brake ineffective.
Conclusion
The accident investigation determined that the brake failure resulted from a chafed brake line, leading to a loss of braking capability on the right side.
