The jet dove into the Java Sea at high speed on October 29, minutes after its takeoff from Jakarta in Indonesia.
Investigators examine engine parts from the ill-fated Lion Air flight JT 610 at a port in Jakarta on November 7, 2018, after they were recovered from the bottom of the Java sea.

Boeing has signalled there could be a problem with the flight control system of its 737 Max 8 jet after one of the new airliners crashed, killing 189 passengers.
Moments earlier, the pilots radioed a request to return to Jakarta to land, but never turned back toward the airport, according to Indonesia's National Transportation Safety Committee and flight-track data.
"But it is quite straightforward and we train for this all the time", the captain said.
These included erroneous speed and altitude data that prompted a flight operated the day before the crash to go into a dive that frightened passengers and a made them sick.
Problems were reported on a Lion Air jet that crashed into the sea off Jakarta even after technicians replaced a sensor on board the aircraft, investigators said.
Boeing has delivered 219 Max planes - the latest and most advanced 737 jets - since the models made their commercial debut previous year with a Lion Air subsidiary.
Boeing said in its statement that it had issued an operations manual bulletin (OMB) to 737 Max operators that advised flight crews to turn to existing procedures "where there is erroneous input from an AOA sensor". "NTSC wants to explore this", he said.
The plane maker said local aviation officials believed pilots might have been given wrong information by the plane's automated systems before the fatal crash. Pilots flying with an AOA sensor generating erroneous inputs to the system can experience the inability to engage the aircraft's autopilot system, among other problems. The data from the flight recorder and Boeing's statement have provided the first clues, but rescuers are still searching for the device that records voices in the plane's cockpit.
Boeing, which manufactured the Lion Air plane, issues safety-related bulletins, and had previously circulated instructions about what flight crews should do if sensors fail.
The Lion Air crash involved a brand new Boeing Max 8 jet, which was cleared to fly despite days of inaccurate speed readings.
Search and rescue agency head Muhammad Syaugi tearfully apologised Monday as relatives' clamour for answers grew louder, with accusations that the pace of recovery is lagging.
A Boeing spokesman said an investigation into the deadly crash revealed the faulty sensor.
