Accident Details
Fifty minutes after takeoff from Brasília, while at cruising altitude on a flight to Rio Verde, the crew lost control of the aircraft. The aircraft entered a dive and crashed in an open field located near Guapó. The aircraft was totally destroyed, and all nine occupants were killed.
Investigation Findings
Investigators determined that at the time of impact, both engines were running at cruise power. On takeoff from Brasília Airport, the total weight of the aircraft was 436 kilograms above the maximum takeoff weight (MTOW), which may have contributed to the accident. However, investigations were unable to determine the exact cause of the accident.
Possible Factors
The investigation noted that the pilot-in-command may have made a brutal movement on the control column, causing the aircraft to become uncontrollable following a structural failure of both winglets that were recently installed.
