The plane's pilot had asked for an emergency landing at Mariquita airport but the aircraft never got that far, said Colonel Carlos Roche, deputy director of Colombia's aviation authority.
"Unfortunately, it didn't make it and crashed eight miles (13 kilometers) from the airport," killing the two pilots and eight passengers, he said yesterday.
Among them were five children, the aviation authority added. All those on board the Piper PA-31 Navajo plane were Colombian.
Investigators are at the crash site and rescuers had recovered the victims' charred bodies.
