If such was the case, the instructor, who was pilot-in-command, may have failed to brief or supervise the co-pilot properly.The Argentinian government issued the following statement:[1] Argentina has determined, in the light of information it has gathered, that the cause of the accident was: "Failure to operate under IFR during a takeoff by night in weather conditions requiring IFR operation and failure to follow the climb procedure for this type of aircraft; a contributory cause was the lack of vigilance by the pilot-in-command during the operations."
