According to the weight and balance sheet, on board the aircraft were two pilots, five flight attendants and 181 passengers consisted of 178 adult, one child and two infants. The scheduled time of departure from Jakarta was 0545 LT (2245 UTC3 on 28 October 2018) as LNI610. The Indonesian government deployed a search and rescue operation which found debris early the same morning and recovered human remains from a 150-nautical-mile (280 km) wide area. The TE controller responded that the aircraft altitude was 900 feet and was acknowledged by the LNI610 Second in Command (SIC).

The voyage report5 showed that the number of flight attendant on board was six flight attendants.

At 23:29:45 UTC, the TE controller instructed the LNI610 to maintain heading 050° and contact the Arrival (ARR) controller.

The ARR controller acknowledged then stated “LNI610 no restriction”. Detailed reports from that flight revealed that the aircraft had suffered a serious incident, which left many passengers traumatized. JAKARTA (Reuters) - Indonesian authorities do not plan to provide a public update on the contents of a cockpit voice recorder from a Lion Air jet that crashed, killing 189 people, until a final report is released in August or September, an official said on Tuesday. The LNI610 descended from altitude 1,700 to 1,600 feet and the TE controller then asked the LNI610 of the intended altitude. The transcription would not be made public until KNKT’s final report is released “between August to September”, he said. Lion Air Flight 610 was a scheduled domestic flight operated by the Indonesian airline Lion Air from Soekarno–Hatta International Airport in Jakarta to Depati Amir Airport in Pangkal Pinang. At 23:28:15 UTC, the TE controller provided traffic information to the LNI610 who responded “ZERO”. Thereafter, the TE controller instructed the LNI610 to climb to altitude 27,000 feet. During rotation the left control column stick shaker7 activated and continued for most of the flight. At 23:29:37 UTC, the TE controller questioned the LNI610 whether the aircraft was descending as the TE controller noticed that the aircraft was descending. The Oct. 29 crash, which killed all those on board, was the world’s first of a Boeing Co 737 MAX jet and the deadliest of 2018. At 23:27:15 UTC, the TE controller instructed the LNI610 to turn right heading 090° which was acknowledged by the LNI610 SIC. The chief executive officer of Lion Air, Edward Sirait, said the aircraft had a "technical issue" on Sunday night, but this had been addressed in accordance with maintenance manuals issued by the manufacturer. At 23:26:32 UTC, the TE controller instructed the LNI610 to turn right heading 050° and maintain altitude of 5,000 feet. The ARR controller asked what altitude the pilot wanted. The debris was later identified as LNI610. At 2320 UTC, the aircraft departed from Jakarta using runway 25L and intended cruising altitude was 27,000 feet. At 23:21:53 UTC, the LNI610 SIC requested approval to the TE controller “to some holding point”. Shortly after departure, the Jakarta Tower controller instructed LNI610 to contact Terminal East (TE) controller. The preliminary report released by KNKT in November focused on airline maintenance and training, as well as the response of a Boeing anti-stall system and a recently replaced sensor, but did not give a cause for the crash.

At 23:31:54 UTC, the FDR stopped recording. A few second later, the TE controller revised the instruction to stop the turn and fly heading 070° which was acknowledged by the LNI610 SIC. Subsequently, the National Transportation Safety Committee confirmed the presence of an off-duty Boeing 737 MAX 8 qualified pilot in the cockpit but did not confirm the role of the pilot in fixing the problem, and denied that there was any recording of the previous flight in the CVR of Lion Air Flight 610.On 29 October 2018, a Boeing 737-8 (MAX) aircraft registered PK-LQP was being operated by PT.

At 23:21:28 UTC, the LNI610 SIC asked the TE controller to confirm the altitude of the aircraft as shown on the TE controller radar display. At 23:24:51 UTC, the TE controller added “FLIGHT CONT TROB” text for LNI610 target label on the controller radar system as reminder that the flight was experiencing flight control problem.
