The process of analysing the Black Box and other vital components of the Air India aircraft that crashed on Saturday began today in New Delhi. <br/><br/>The Cockpit Voice Recorder and the Digital Flight Data Acquisition Unit which record the cockpit audio and technical details of the plane, were opened for preliminary analysis by experts and officials of the Air Safety Directorate to ascertain the cause of the accident. <br/><br/>These two vital components were brought to the DGCA headquarters from the Mangalore crash site last night. <br/><br/>The Sources said, officials of various divisions of the DGCA, Air India's engineering department, aircraft manufacturer Boeing and other technical experts held a series of meetings during the day. <br/><br/>Several kinds of tests would be conducted on the Flight Data Recorder (FDR) or the Black Box, which has been damaged in the crash, to decode it. <br/><br/>The entire process of opening up and carrying out preliminary examination of these devices would take several weeks, the sources said. <br/><br/>These components, including the FDR, could also be sent to the US, where the Boeing 737-800 was manufactured, for technical analysis. <br/><br/>Four teams of investigators from engineering, operations, ATC and aerodrome units, which inspected the wreckage, the runway and the accident site, would now pool in their resources to carry out their task further.
