Lion Air flight 610, a Boeing 737 MAX 8, crashed into the sea shortly after takeoff from Jakarta-Soekarno-Hatta International Airport, Indonesia. The flight took off from runway 25L at Soekarno-Hatta Airport at 06:21 hours local time. Weather was fine with light winds, scattered clouds at 2000 feet and a visibility of 8000 m.
The aircraft made a climbing left hand turn after takeoff. Shortly afterwards the flight crew radioed the controller, requesting a return to the airport.
After the flight passed the ADS-B reported altitude of 2100 feet, data points briefly show a lower altitude of around 1475 feet. Altitude data sent via ADS-B continue to show an erratic pattern, varying roughly between 4500 and 5350 feet, The values then rapidly decline until contact is lost at 06:32 hours. The aircraft impacted the sea some 15 km north off Jakarta. All 189 persons on board died in the accident.
Search and rescue personnel recovered the flight data recorder (FDR) and other debris on November 1, at 30-35 m below the water surface. Indonesian investigators of the NTSC subsequently revealed that the aircraft experienced erroneous input from one of its AOA (Angle of Attack) sensors.
If the flight control system on a Boeing 737 MAX aircraft receives an erroneously high single AOA sensor input, there is a potential for repeated nose-down trim commands of the horizontal stabilizer. Such a specific condition could among others potentially result in the stick shaker activating on the affected side and IAS, ALT and/or AOA DISAGREE alerts.
The NTSC reported that an airspeed indication anomaly did occur on the accident aircraft's last four flights.

On November 6, 2018, Boeing issued an Operations Manual Bulletin (OMB) directing operators to existing flight crew procedures to address circumstances where there is erroneous input from an AOA sensor.
On November 7, the FAA issued an emergency Airworthiness Directive requiring "revising certificate limitations and operating procedures of the airplane flight manual (AFM) to provide the flight crew with runaway horizontal stabilizer trim procedures to follow under certain conditions."
