What happened
A scheduled flight, identified as JJ3804, departed from São Paulo-Guarulhos Airport bound for Campo Grande. The Embraer aircraft was transporting 24 passengers and five crew members at the time of the incident.
While cruising at an altitude of 35,000 feet, the flight crew identified technical difficulties involving the fuel system. In response to these issues, an emergency was declared, and the aircraft was authorized to divert to Araçatuba Airport. During the approach phase, at approximately 1,639 feet, both engines ceased functioning. Realizing that the destination airport was no longer reachable, the pilot attempted an emergency touchdown in a prairie situated roughly 29.5 km from the airfield.
Upon impact with the ground, the aircraft's landing gear collapsed, causing the plane to slide across the terrain. The accident also involved a collision with livestock. While all 29 occupants successfully evacuated the aircraft, four injuries were reported among the group. The aircraft sustained damage that rendered it a total loss.
Findings
Investigations into the engine failure revealed that the crew initially observed low fuel pressure in the right engine and identified issues with the fuel filter. Following an assessment of the flight manual, the crew attempted to manage a fuel transfer problem during the diversion.
The primary reason for the dual engine shutdown was a rupture of a fuel line connected to the right engine, which led to a significant leak. This failure was traced back to the breakage of an aluminum ring, which caused the fuel line to disconnect.
