Colombia crash - Why on earth didn`t the captain declare an emergency? - Curt Lewis

Mystery of downed LaMia jet: did captain know he was heading for trouble? Pilot of plane carrying Chapecoense football team did not declare a fuel emergency The plane was ordered to circle the airport to allow another plane to land. It is feared the manoeuvre exhausted the available fuel AP As investigators pore over the sequence of events that led to the worst air disaster of 2016, attention is focused on the captain of the plane, Miguel Quiroga, and the decisions he took on fuel provision and alerting air-traffic control. Seventy-one people, including most of the players on a leading Brazilian football team, died when their chartered Avro RJ85 jet crashed on the approach to Medellín's main airport. They had departed from Santa Cruz in Bolivia on the final leg of a journey to the Colombian city for the first leg of the Copa Sudamerica final. The aircraft was chartered from LaMia, based in Santa Cruz. Bolivia's aviation authority, the DGAC, has grounded the airline indefinitely. The initial decision to deploy a commuter jet designed for short hops on a flight of 1,850 miles looks questionable. The journey is the same distance as Belfast to Istanbul - a route that would not be sanctioned as a regular scheduled route using such a plane. The longest regular trip made by the aircraft type is believed to be 1,625 miles between Perth in Australia and Christmas Island, a journey of about four hours. The RJ85 had been flying for almost five hours when it crashed. A flight plan leaked to the media shows the "estimated elapsed time" - ie the predicted length of the flight - as four hours, 22 minutes. The "endurance", or maximum flying time, is shown as exactly the same. Three hours into LaMia flight 2933, the aircraft passed over Leticia airport, in the Colombian Amazon. By this stage the pilots should have had a clear picture of the amount of fuel remaining in the tanks. About four hours into the flight, the aircraft could have diverted to Bogota, the declared alternate airport. At about that time, an AeroColombia flight took off from the Colombian capital, destined for the Caribbean island of San Andres. It then declared a diversion to Medellín because of a mechanical fault. The LaMia aircraft was ordered to fly a holding pattern while the AeroColombia flight was given priority to land. It is feared the manoeuvre exhausted the available fuel. International aviation law requires the pilot-in-command to ensure that there is always enough fuel on board "to proceed to an aerodrome where a safe landing can be made with the planned final reserve fuel remaining upon landing." The absolute minimum "planned final reserve fuel" allows for the aircraft to fly for half an hour at holding speed at an altitude of 1,500 feet above the airport. When the crew predict that landing at the nearest safe airport will result in having less than the planned final reserve, they are required to declare a fuel emergency by broadcasting "Mayday, Mayday, Mayday, Fuel". Air-traffic controllers are then obliged to prioritise the aircraft to enable it to land as soon as possible. From the leaked recording of the conversation with air-traffic control, it appears that no fuel emergency was ever declared. The transcript indicates a pilot saying only "it's in failure, uh, total... electrical and fuel". There is no clear evidence that the aircraft ran out of fuel through mismanagement. Alternative explanations include faulty fuel gauges, a fuel leak, or an issue with the complex fuelling system for the four-engined aircraft. But there are echoes of a crash on the approach to New York JFK of a Colombian plane in 1990. Eighty-three people died when the Boeing 707 from Medellín crashed well short of the runway after running out of fuel. The investigation blamed "the failure of the flightcrew to adequately manage the airplane's fuel load, and their failure to communicate an emergency fuel situation to air traffic control". Any captain who declares a fuel emergency faces an investigation from the aviation authorities, with possible consequences for the airline. Captain Quiroga was part-owner of LaMia.

Chapecoense plane crash: Pilot 'was warned over fuel' The pilot of a charter plane that crashed in Colombia on Monday had been warned before taking off from an airport in Bolivia that he might not have enough fuel, a report says. An airport official raised the concern after checking the plane's flight plan, Bolivia's Deber newspaper said. Seventy-one people died in the crash, including members of a Brazilian football team. Six people survived. Bodies of the victims are due to be repatriated to Brazil. Colombian authorities have said evidence is growing that the British-made BAE 146 Avro RJ85 aircraft ran out of fuel as it tried to land at Medellin airport. Experts say it was flying at, or very near, its maximum range. In a leaked tape, the pilot, Miguel Quiroga, can be heard warning of a "total electric failure" and "lack of fuel". On Thursday, Bolivia's aviation authority suspended the operating licence of charter airline LaMia, which was part-owned by Mr Quiroga, and two other aviation officials. In the report carried in Deber, the Bolivian airport authority official at Santa Cruz airport said she raised concerns that the plane's fuel load was only enough for the exact flight time. The paper said she described how the airline's clerk, who died in the crash, had told her the pilot was confident he had enough fuel. Despite her concerns, the flight plan was passed on to Bolivian air control. Bolivian officials have not yet commented on the report. Map of aircraft's route An earlier report carried by Brazil's O Globo newspaper suggested that because of a delayed departure, a refuelling stop in Cobija - on the border between Brazil and Bolivia - was abandoned because the airport did not operate at night. The pilot had the option to refuel in Bogota, it said, but headed straight to Medellin. The chief executive of LaMia, Gustavo Vargas, said on Wednesday that the plane should have had enough fuel for about four and a half hours and any decision to refuel was at the pilot's discretion. In another development, the Colombian air traffic controller who received the distress call said she had received death threats following the crash. "I did all that was humanly possible and technically necessary to preserve the lives of the passengers, but unfortunately my efforts weren't enough," Yaneth Molina wrote in a letter to her colleagues that was later released to the media. On the approach to Medellin, the pilot had initially sought permission to land urgently but another plane was given priority because it had suffered a fuel leak. The LaMia flight was told to circle for seven minutes. Meanwhile, coffins of the Brazilian victims are due to be flown out of Medellin on Friday. Colombian officials say the plane's "black boxes", which record flight details, will be sent to the UK to be opened by investigators. A full investigation into the crash is expected to take months.
