Accident Details
An airline transport pilot was conducting a personal cross-country flight under Title 14, CFR Part 91, with three passengers. The accident occurred during the landing roll.
Pilot Account
The pilot reported that during the landing roll, the right main landing gear brake did not function. He attempted to maintain a straight path but the airplane drifted to the right side of the runway. Subsequently, the airplane ground-looped to the left. The pilot noted that the right wing, aileron, horizontal stabilizer, and elevator sustained damage during the ground-loop. He stated that there were no known mechanical problems with the airplane prior to the accident.
Examination Findings
An examination of the right brake system revealed that the set-screw securing the right brake cylinder cap had not been properly installed. This allowed the cap to detach from the cylinder and jam the right rudder/brake pedal.
