Taking the 737 to the Max
summary
A detailed timeline ties specific design choices to outcomes: Boeing adds MCAS to mimic older 737 handling, lets it run from a single angle-of-attack sensor, and changes activation from 0.6° → 2.5° nose-down trim. Two flights suffer repeated automatic trim inputs, one plunges 5,000 ft killing 189 people, and the fleet is grounded for one year and eight months. Certification delegation, simulator requirements, and MCAS logic are changed and the revised system limits activations to prevent recurrence.
