Emergency workers have found the black boxes with flight data and cockpit voice recordings from a plane that crashed in the Colombian mountains with a Brazilian football team on board, France 24 reported Wednesday.

Luis Perez Gutierrez, the governor for Antioquia department in northwestern Colombia, where the charter flight went down, announced the two black boxes had been located. Aviation officials later confirmed the find.

Officials did not immediately say how long it would take to analyse their contents.

The LAMIA aircraft was flying from Brazil via Bolivia to Medellin when it crashed in an area called Cerro Gordo about 50 kilometres from the city, Colombia's second largest.

"Search and rescue operations found 71 victims and six survivors," Colombia's disaster management agency, UNGRD, said in a statement late Tuesday.

The civil aviation authority had earlier given a death toll of 75, but it later emerged that four people on the passenger manifest had not in fact boarded the plane.
