Investigators on Tuesday recovered the crucial ‘Black Box’— the Digital Flight Data Recorder(DFDR)- from the wreckage of the Boeing plane of Air India’s budget carrier, three days after it crashed here while landing killing 158 persons. The data recorder, mounted in the aircraft’s tail and which stores key information, could give vital clues on what caused the country’s worst air crash in a decade on last Saturday.
The instrument, which will have data on a range of parameters and information on pilot’s response, was damaged on one side but Directorate General of Civil Aviation(DGCA) officials said it was intact with the "main memory."
"Nothing has happened to the main portion where the main memory is located. It is intact," DGCA officials said shortly after they made the breakthrough around 10 am.
A relieved Air India’s General Manager,(Flight and Safety) Mr G.M. Mathew, held the black box which was charred in some places aloft and showed it to the media at the site of the wreckage which was thoroughly combed after investigators widened the search area.
"What was recovered on Tuesday is the main part(of the black box)," Mr Mathew said. The DFDR logs actual flight conditions, including altitude, airspeed, heading and vertical acceleration.
Investigators had on May 23 recovered the Cockpit Voice Recorder (CVR) and Digital Flight Data Acquisition Unit (DFDAU) from the wreckage of the ill-fated flight of Air India Express from Dubai(IX 812). They were brought to New Delhi last night. The Boeing 737-800 crashed at around 6.30 am on last Saturday after the pilot overshot the runway. Eight persons miraculously survived the crash.
The Black Box will be brought to New Delhi for a preliminary analysis amid reports that it may be later sent to the US for a detailed examination. Results from the analysis are likely to available in a few weeks.
The DGCA officials said the search operations had been called off following recovery of the DFDR which would help in reconstructing the events leading to the crash.(PTI)
