the bodies and was unable to identify the other 43. Of the deceased, the following causes of death were established: 108 died from serious poly-traumatic injuries, 22 died from a combination of drowning and serious poly-traumatic injuries, and 15 died solely from drowning. The hospital could not determine the injuries sustained by one of the 146 bodies. According to the autopsy reports, a violent deceleration or a twisting or cutting action resulted in the injuries. Forty-three of the deceased received first-degree burns due to contact with the jet fuel spilled in the water. The pilots died from poly-traumatic injuries; they also received first-degree burns from the jet fuel. Investigation The Bureau of Enquiry and Analysis for Civil Aviation Safety (BEA), the accident investigation authority of France, assisted in the search for the flight recorders. The Transportation Safety Board of Canada (TSB) analysed the flight safety recorders. The Ministry of Transport of the Ivory Coast published the original French-language accident report and the BEA published its English version of the report. The flight data recorder (FDR) was located by recovery team on 2 February at a depth of 50 meters, located among the wreckage of the aircraft. The FDR was eventually sent to Ottawa on 21 February and a readout was conducted on 24 February. The cockpit voice recorder (CVR) was recovered on 24 February in the same area where the FDR had been found. It was sent to Canada at the very same day. The CVR managed to record the last 30 minutes of the flight and investigators managed to produce a transcript from the readout. The flight data recorder, however, had recorded values unrelated to the flight and therefore was unusable. The crash site was mapped by authorities from 21 - 24 March 2001 and an underwater mapping was conducted on 12 - 16 April 2001. The wreckage was spread over an area of 150 meters wide and 450 meters long, with a various depths of 40 to 50 meters. The debris from the wreckage had spread to various directions due to the strong underwater currents in the area. According to investigators, several debris, including half of the aircraft's main landing gear and the fin, had been recovered on beaches nearby. Stall warning The activation of the aircraft's stall warning aboard Flight 431 might have been caused by several scenarios; an incorrect configuration on take-off, an incorrect speed indication,
