On December 29th, according to the Korean Air Railway Accident Investigation Committee, the outer part of the flight data recorder in the two “black boxes” of Jeju Air Flight 7C2216 was damaged, while the other cockpit voice recorder was well preserved. The Air Railway Accident Investigation Committee pointed out that the interpretation of the “black box” usually takes about a week, but the interpretation of the damaged flight data recorder may take about a month. If the damage to the flight data recorder is severe, it may need to be handed over to the National Transportation Safety Board for interpretation. In this case, the interpretation of the black box alone will take more than 6 months, which will inevitably affect the progress of the investigation into the cause of the accident.
