The flight-control feature implicated in two fatal crashes on Boeing’s 737 Max was built on a foundation of false assumptions.
Boeing underestimated its risks, didn’t consider how changes to the system would heighten the danger and kept some of the government regulators overseeing the plane’s design in the dark, a report by Indonesian investigators concluded.
The most comprehensive review to date of the Maneuvering Characteristics Augmentation System also found that the U.S. Federal Aviation Administration delegated too much authority to Boeing for its approval.
