Incident
During an en route flight, the aircraft experienced a failure of its right engine. In response, the crew jettisoned some of the cargo in an attempt to maintain a safe altitude. Despite these efforts, the aircraft subsequently stalled and crashed into hilly, wooded terrain in the Cachimbo region.
Aftermath
The wreckage was located a few hours later in the jungle. All 15 occupants of the aircraft were killed in the accident.
Probable Cause
The official investigation determined that the probable cause of the accident was an in-flight failure of the right engine for unknown reasons.
