Four minutes prior to the accident, the country’s transportation department said, the North Korean passenger plane’s cockpit voice recorders and flight data stopped recording.
The Jeju Air flight crash, which resulted in 179 fatalities, is the deadliest atmosphere accident ever to occur on Asian soil. Two cabin crew members were the only victims.
Investigators had hoped that the records ‘ data may reveal more about the important events that had occurred before the drama.
The government said it would investigate what caused the “black containers” to prevent recording.
The government claimed that the devices were initially examined in South Korea.
When it was discovered that the data was missing, British security regulators examined them and sent them to the US.
When the plane crashed-landed at Muan International Airport on December 29 and slid into a roof off the airport, igniting lights, it was flying from Bangkok.
Sim Jai-dong, a past accident analyst for the transport department, told Reuters reports that the loss of information from the crucial last minutes was unexpected and suggested that all power, including backup, could have been cut.
Many questions remain unanswered. Investigators have been looking at the role that a bird strike or weather conditions may have played.
They have even emphasized why the landing gear on the Boeing 737-800 did not deploy when it first hit the airport.
