Boeing developed the MCAS system, a critical flight control software designed to prevent stalls, but deliberately concealed its existence and functionality from pilots and the FAA. This secrecy was driven by a desire to avoid triggering costly pilot retraining requirements and to make the 737 MAX appear as a minor update, thereby appeasing airlines and maintaining competitiveness.
Impact: High. The lack of transparency surrounding MCAS meant pilots were unprepared for its actions, turning a safety feature into a deadly trap when it malfunctioned.
