What happened
A twin-engine airplane was performing a taxi flight from Manaus toward Santa Isabel do Rio Negro-Tapuruquara Airport when the crew encountered unidentified technical difficulties. In response to these issues, the pilots decided to descend and divert the flight to Barcelos Airport.
During the approach to the diversion airport, the aircraft became uncontrollable. The plane struck the surface of the Río Negro River and was subsequently pulled under by powerful currents. There were five fatalities among the occupants, which included two pilots and three technicians employed by a mining firm.
Findings
The investigation indicates that unidentified technical problems necessitated the emergency diversion to Barcelos, which preceded the loss of control during the final approach.
