Despite the crew's strenuous efforts to maintain control, the plane crashed into the Java Sea just 13 minutes into the flight. Regulators in multiple countries moved to ground the 737 MAX, and airlines canceled thousands of flights.
Applying Future Aviation Safety Lessons to Prevent Boeing MCAS-Type Crashes
The flight data recorder indicated that the MCAS system was receiving erroneous signals from a single angle-of-attack sensor, causing the aircraft to nose down repeatedly. Less than five months later, Ethiopian Airlines Flight 302 met a similar fate near Addis Ababa, exhibiting nearly identical technical malfunctions.
The uncanny resemblance between the two disasters triggered immediate global scrutiny and grounded the entire 737 MAX fleet. The MCAS interpreted this incorrect data as an imminent stall and commanded a nose-down input.
