What happened
During the flight, the aircraft experienced a mechanical failure involving the right engine. In an attempt to preserve enough altitude for continued flight, the crew performed an emergency jettison of a portion of the cargo. Despite these efforts, the aircraft eventually entered a stall condition.
The plane impacted hilly and heavily forested terrain within the Cachimbo region. Search teams located the wreckage in the jungle several hours after the incident occurred. There were no survivors among the 15 fatalities recorded on board.
Findings
Investigations into the accident focused on the mechanical issues experienced during the flight. The primary factor leading to the crash was the failure of the right engine while in flight, which prevented the aircraft from maintaining its necessary flight path.
