The NTSC gave the recommendation when announcing its preliminaryfindings into the accident. The Boeing 737 MAX vanished from radar about 13minutes after taking off from Jakarta on October 29, slamming into the Java Seamoments after it had asked to return to the capital.
The agency did not pinpoint a definitive cause of the accident, with afinal crash report not likely to be filed until next year.
But its investigators said that Lion Air kept putting the plane backinto service despite repeatedly failing to fix a problem with the airspeedindicator in the days leading up to the fatal flight.
The October 28 flight from Bali to Jakarta had experienced similartechnical issues to the doomed flight the next day from Jakarta to PangkalPinang, said Nurcahyo Utomo, head of the NTSC.
The report also suggested the pilots struggled with the plane'santi-stall system as they radioed in a request to return to Jakarta's mainairport.
Investigators have previously said the doomed aircraft had problems withits airspeed indicator and angle of attack (AOA) sensors, prompting Boeing to issuea special bulletin telling operators what to do when they face the same situation.
Black box data collected from their crashed plane showed that pilotsstruggled to maintain control as the aircraft's automatic safety systemrepeatedly pushed the plane's nose down.
The investigators are focusing on whether faulty information fromsensors led the plane's system to force the nose down.-VNA
