A recording had already indicated the aircraft had run out of fuel.

The plane, operated by Bolivian company LaMia, plunged into a mountainside near Medellin. Only six people survived.

Preliminary results of the Colombian investigation said the pilot failed to refuel en route and was too late in reporting engine failures caused by the lack of fuel.
