The Role of Angle of Attack Sensors A central technical issue in both crashes was the reliance on a single angle-of-attack (AOA) sensor. Despite the crew's strenuous efforts to maintain control, the plane crashed into the Java Sea just 13 minutes into the flight.

This sensor provides critical data to the aircraft's systems, including MCAS, to determine the airflow over the wings. Compounding the problem, the system used this single data point and could repeatedly command the stabilizer trim, overpowering the pilots' control inputs.
Key Incidents and Timeline of the Crisis The first red flag emerged with Lion Air Flight 610 shortly after takeoff from Jakarta in October 2018. The system is designed to automatically push the nose of the aircraft down if it detects an excessive angle of attack, preventing a stall.

The incidents exposed critical vulnerabilities in how new automation systems are integrated and certified, raising profound questions about the balance between technological advancement and pilot authority in modern aviation. Understanding the Maneuvering Characteristics Augmentation System MCAS, or Maneuvering Characteristics Augmentation System, is a proprietary automated technology embedded within the Boeing 737 MAX series.
