Doomed by a series of flaws

JAKARTA: Boeing, acting without adequate oversight from US regulators, failed to grasp risks in the design of cockpit software on its 737 MAX airliner, sowing the seeds for a Lion Air crash that also involved errors by airline workers and crew, Indonesian investigators found.

The fatal crash, followed less than five months by another at Ethiopian Airlines, led to a global grounding of the Boeing 737 MAX and a crisis for the world’s biggest planemaker, which this week ousted its commercial airplanes chief.
