What happened
A cargo mission traveling from Santa Cruz to Arica, Chile, ended in a fatal accident when a four-engine airplane collided with the terrain. While the flight was being conducted under Visual Flight Rules (VFR) at an altitude of 18,000 feet, the crew encountered deteriorating weather conditions. During this period of low visibility, the aircraft struck the slope of Mt Nevados de Putre, situated approximately 12 km northeast of Putre.
Search efforts located the wreckage a few hours after the impact. The accident resulted in six fatalities, with no survivors among the occupants of the aircraft.
Findings
Investigations into the crash determined that the crew was operating the aircraft under VFR while actually encountering Instrument Meteorological Conditions (IMC). This led to a controlled flight into terrain.
