Accident Sequence
The pilot reported that during the landing roll, the right brake locked and he was unable to maintain directional control. The airplane exited the side of the runway, collided with rough terrain, and the nose gear collapsed. Approximately 480 feet of skid mark was visible on the runway from the right gear.
Post-Accident Findings
After the accident, the wheels and brakes were visually inspected, functionally tested, and disassembled. No anomalies or mechanical discrepancies were noted. Floor carpeting was found to be 'bunched up' by one of the brake pedals, but no positive determination could be made as to the effect of the carpet on brake pedal performance. A review of the maintenance log books did not reveal evidence of unresolved discrepancies.
Pilot Report
