Incident Overview
During the landing roll, the pilot applied toe brakes. The right brake pedal traveled to the floor. The aircraft then veered left of the centerline despite the pilot's attempt to groundloop the aircraft. Subsequently, the aircraft rolled over an embankment, collapsing the right main landing gear and the nose gear.
Investigation Findings
Examination of the braking system revealed that the right brake disc had failed in the area of a weld. The disc also showed evidence of corrosion and uneven wear. Additionally, the brake linings were found to have been worn. The aircraft had flown 100 hours since the last annual inspection.
