Incident
Following an uneventful flight, the twin-engine aircraft approached Andahuaylas Airport and landed normally on runway 03. After touchdown, while decelerating to a speed of about 40 knots, the aircraft started to deviate to the left. The crew counteracted but the aircraft continued to the left, veered off the runway, rolled through grassy terrain, and eventually came down a four-meter-high embankment before coming to rest. All 19 occupants escaped uninjured. The aircraft was damaged beyond repair.
Probable Cause
According to the official investigation, the loss of directional control after touchdown was caused by the failure of the brake systems. The aircraft had already experienced several technical problems with its brake systems prior to the flight, and maintenance was performed by technicians the day before the accident. For unknown reasons, the problem was resolved, but no feedback or troubleshooting was performed on part of the technicians or the crew. The captain was aware of the problem and took the decision to complete the flight despite the risk that the problem might persist or recur.
