The checklists provided were ambiguous and did not directly address the runaway trim scenario caused by MCAS. Lack of Redundancy MCAS could activate repeatedly without pilot or system awareness of its origin.

In both incidents, pilots were confronted with an unresponsive stabilizer trim system and an overwhelming barrage of alerts, including the activation of the stick shaker—a stall warning that should never have been active in level flight. Control System Logic Trim commands were mechanically linked, overriding pilot control inputs.
Checklist Ambiguity Procedures did not clearly guide pilots to diagnose and counteract the runaway trim. Furthermore, the system was certified under an assumption that a single-point failure would be addressed by pilot training and procedures, a calculation that failed to account for the simultaneous failure of a primary instrument and the physical limitations a pilot faces during an unexpected high-speed dive.

The Core Culprit: Maneuvering Characteristics Augmentation System (MCAS) The central technical element behind both accidents was the Maneuvering Characteristics Augmentation System, a new automated feature introduced with the 737 MAX to address a critical aerodynamic shift. This led to decisions that masked the novel MCAS system from pilots; it was not prominently featured in the flight manual as a system that could repeatedly command stabilizer trim against pilot input.
