Compounding the problem, the system used this single data point and could repeatedly command the stabilizer trim, overpowering the pilots' control inputs. 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.
Design Flaws in Boeing's Safety System and Angle of Attack Sensor Reliance
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. The Boeing MCAS crash refers to a series of accidents involving the Boeing 737 MAX aircraft, most notably Lion Air Flight 610 in October 2018 and Ethiopian Airlines Flight 302 in March 2019.
5 billion to resolve criminal charges, including fraud allegations related to misleading regulators about the 737 MAX's safety. These tragedies resulted in the loss of 346 lives and initiated a comprehensive reevaluation of aviation safety protocols, regulatory oversight, and aircraft design philosophy.

This sensor provides critical data to the aircraft's systems, including MCAS, to determine the airflow over the wings. The uncanny resemblance between the two disasters triggered immediate global scrutiny and grounded the entire 737 MAX fleet.
