Black box revealed unexpected information about falling Indonesian aircraft

Lion Air crashed into the Java Sea last week, killing 189 people, having had problems in previous flights.

According to the South China Morning Post (SCMP), the new information was extracted from the black box of the JT610 numbered aircraft after the Indonesian government opened an investigation of the operation of Lion Air.

The first black box of the JT610 aircraft is a device that records flight data.

Indonesia's National Traffic Safety Committee (NTSC) said on November 5 that aircraft black box data showed that the Boeing 737 MAX 8 had a problem with the device showing a long speed.

'There are 4 flights having problems with speed display system' , the head of NTSC, Soerjanto Tjahjono told reporters. 'When there is a problem, the pilot will pay attention to the technical staff to fix it. And now the plane is eligible for further flight '.

This issue was discovered after authorities extracted 69 hours of data from the black box recording the JT610 flight and previous flights.

Tjahjono added that the plane had crashed when crashing into the sea, rather than breaking from the air as determined. Some experts also believe that the Boeing 737 MAX 8 can crash into the sea at speeds of more than 1,000 km / h, so it is not easy to find large debris.

NTSC will continue to investigate what is causing the problem and whether it will be repaired. NTSC did not comment on the relationship between the problem and the cause of the crash.

Divers have found many JT610 aircraft fragments falling into the Java Sea.

Lion Air had previously admitted that the plane crashed had problems before. The pilot asked to turn his head a few minutes after taking off, reinforcing the question of the aircraft having technical problems.

Indonesian divers are still looking for the second black box to store the cockpit recording tape segment. According to sources, the JT610 aircraft accelerated abruptly and crashed straight into the sea, 13 minutes after taking off at Jakarta airport.

Lion Air is at the center of complaints about poor service, delays and safety issues, including a fatal accident in 2004. 25 people were killed when the flight with the number 538 fell. Cemetery in Surakarta.

'This is an expensive lesson for us,' said Indonesian Transport Minister Budi Karya Sumadi.
