The captain tried to lift the nose of the aircraft, but the automatic anti-motor system left him.

The pilots of this flight reported a problem to the maintenance team of Lion Air, who, after checking the plane, had given permission to start the next day, flight that connected Jakarta to Pangkal Pinang. After the disaster, the Lion Air authorities asked the pilots to provide the technical team with a complete description of the technical defects.

For the moment without any reason

In an initial report, Indonesia indicated the airline's service procedures, pilot training and the anti-stall system used by Boeing, but did not explicitly state the cause of the disaster .

KNKT investigator Nurcahyo Utomo said the agency had not yet determined whether the anti-stall system was the cause of the disaster. "We do not know yet whether he contributed or not, it is too early to draw any conclusions – he said.

In a statement released, Boeing drew attention to the operation of the technical team, but did not blame the disaster, neither its members nor its pilots.
