On October 11, 1996, a Swearingen SA226 Metro II (registration CP-1516) operated by Servicios y Transportes Aéreos Petroleros - STAP was involved in an aviation accident near Cuiabá-Marechal Rondon, Brazil during landing or approach. No fatalities were reported. Investigators recorded the probable cause as: The loss of directional control occurred after the crew deactivated the reverse thrust during the braking process. This summary draws on records from the Bureau of Aircraft Accidents Archives (B3A); 2 related events involving the same aircraft type or operator are linked below.
An aircraft veered off the runway at Cuiabá-Marechal Rondon Airport during the landing roll, resulting in significant damage but no injuries.
What happened
Upon completing the landing phase at Cuiabá-Marechal Rondon Airport, the flight crew initiated standard braking protocols. Shortly after the aircraft made contact with the runway, the crew deactivated the reverse thrust mechanism. Following this action, the aircraft experienced a loss of directional control and drifted toward the right side of the runway.
As the excursion continued, the aircraft's landing gear separated from the airframe. The movement ended several dozen meters away from the runway surface. Although the aircraft sustained damage that rendered it a total loss, all 15 occupants managed to exit the wreckage without sustaining any injuries.
Findings
The loss of control occurred immediately following the deactivation of the reverse thrust system during the landing roll.
Probable cause
The loss of directional control occurred after the crew deactivated the reverse thrust during the braking process.
