Lion Air Flight 610

Lion Air Flight 610, a Boeing 737 MAX 8, crashed into the Java Sea on 29 October 2018, 13 minutes after takeoff, killing all 189 on board. The crash was caused by a faulty angle-of-attack sensor that fed erroneous data to the MCAS system, repeatedly pushing the aircraft's nose down. The pilots did not follow proper procedures to disable the system. The investigation found that Boeing did not inform pilots about MCAS, the FAA certification process was flawed, and maintenance issues at Lion Air and the sensor supplier Xtra Aerospace contributed. The crash led to the global grounding of all 737 MAX aircraft after a similar incident on Ethiopian Airlines Flight 302 in March 2019.
