The Aviation and Railway Accident Investigation Board (ARAIB) of South Korea revealed that the records from the voice recorder and flight recorder of the Jeju Airplane that caught fire at Muan International Airport were interrupted.
The voice recorder was recovered in an undamaged state externally, while the flight recorder was recovered with its connector between the power supply and the data storage unit damaged. The flight recorder’s data extraction could not be performed in South Korea, hence it was conducted at the National Transportation Safety Board (NTSB) in Washington, U.S.
The voice recorder, after having its data extracted and converted into audio files at a test analysis center near Gimpo Airport, was transcribed into text data. It has been understood that the recording stopped about 4 minutes before the aircraft collided with the localizer, and the cause of this is currently unknown. Therefore, like with the flight recorder, analysis at the NTSB revealed that the recording was interrupted for both devices.
The Aviation and Railway Accident Investigation Board has stated that they will strive to provide as much information as possible to the public, family members of victims, when the site investigation is completed, during public hearings, or whenever deemed necessary, in an effort to conduct a fair and transparent accident investigation.
