Incident Overview
A pilot reported that after landing a tailwheel-equipped airplane, ground personnel provided taxi signals to exit the runway. The pilot stated that he applied both brakes firmly, but the left brake failed. This caused the airplane to ground loop off the right side of the runway, resulting in substantial damage to the fuselage near the main landing gear.
Post-Incident Examination
An inspection of the airplane revealed that the left brake was very weak. However, no evidence of leakage was found. The specific cause of the brake weakness was not identified during the examination.
