What happened
While operating in transit, the flight crew notified air traffic control that the right engine had failed. Following this mechanical issue, the crew evaluated options for an emergency landing, considering diversions to either Arica or Tacna.
In an attempt to reach a suitable airfield, the captain increased power to the remaining left engine. However, it became apparent that the aircraft lacked sufficient performance to reach the nearest available airport. Consequently, the pilot attempted an emergency descent toward a plateau situated within the Vizcacha Mountains. During this maneuver, the aircraft type lost altitude and struck a rocky terrain. The impact caused the plane to disintegrate, and all four crew members perished in the accident.
Findings
Investigations into the incident concluded that the failure of the right engine was caused by inappropriate maintenance practices.
