Nearly a month after the deadly crash of a unit of the Bolivian LaMia company in Colombia , the track of the technical factor recedes. According to preliminary results of the investigation of civil aviation presented Monday, December 26 in Bogota, it appears that management errors are at the root of this disaster that killed 71 people, including 19 players from Brazilian club of Chapecoense .
Pilots "were aware of fuel limitations they had, which was not what was appropriate or sufficient" , said the secretary of the security of the Colombian Civil Aviation, Colonel Freddy Bonilla, at a conference Press.
However, they did not inform the Colombian aeronautical authorities and reported that the aircraft was facing an emergency only seven minutes before the impact on the side of a mountain in the vicinity of Medellin (west), on 28 November. The pilot and copilot thought landing in Bogota and Leticia (south) due to "fuel limit" but made no such request, according to Bonilla.
"To date we have no evidence that a technical factor caused the accident, everything is related to a human factor and management" , he said, adding that besides the air excess weight was almost 500 kg but it was not "decisive" in the accident.
The Colombian daily El Tiempo adds that the weather probably played an important role in this disaster: the aircraft had faced headwinds and was forced to divert his route when he entered the airspace of Colombia Due to bad weather. Two events that may have contributed to increase the consumption of the device.
