What happened
The incident involved a training exercise conducted over the Atlantic Ocean. During the mission, meteorological conditions worsened, prompting the flight deck to initiate a return to their home base. As the aircraft progressed toward its destination, the captain determined that remaining fuel reserves were inadequate to complete the journey safely. Consequently, the decision was made to ditch the machine in the water.
The emergency landing occurred roughly 260 km off the coast of Fernando de Noronha Island. The airframe sank rapidly following contact with the sea surface and was subsequently lost. All five individuals on board successfully evacuated the cabin before it submerged. They took refuge in a dinghy until rescue teams arrived to recover and evacuate them.
Findings
Official investigations concluded that the emergency landing resulted from fuel exhaustion while operating in poor weather conditions.
