On Jan 19th 2021 the KNKT reported that the FDR contained 330 parameters of a total of 18 flights. The KNKT have already developed a general picture of the accident, however, need further data from the cockpit voice recorder before publishing any information. Inspections of Boeing 737-300, 737-400 and 737-500 in Indonesia have been ordered.
On Jan 22nd 2021 the KNKT confirmed a preliminary report will be released within 30 days after the accident (until Feb 8th 2021), no other information has yet been released.
On Jan 23rd 2021 the KNKT chairman stated, that the tech log of the aircraft contained an entry about an autothrottle fault a few days before the crash. There has been no other technical anomaly noted. At this time it is entirely unclear whether or not problems with the autothrottle contributed to the crash Crews can easily fly the aircraft manually without the autothrottle system. The CVR will be needed to hear the discussions between the pilots to identify the actual problem they had at hand. (Editorial note: obviously this entire statement came in response to speculations raised by a number of media globally attributing the crash to a malfunction of the autothrottle system).
On Feb 2nd 2021 the KNKT chairman said in a press conference, that reports distributed by western media about a possible autothrottle malfunction causing asymmetric thrust are wrong. However, the KNKT sent 5 pieces of debris, including the autothrottle unit (but not identifying the other parts), to the USA and UK for further examination stating they want to find out why an autothrottle parameter changed. He re-iterated they don't know why that parameter changed and need confirmation from the parts sent to the USA and UK and the CVR. The maritime search for the CVR is still ongoing.
