The final report by air accident investigators into the Lion Air crash of a 737 MAX in Indonesia that killed 189 people a year ago provides a devastating critique of the design and certification of Boeing's new flight-control system on the airplane.
It also provides a detailed account of the fatal flight. And it apportions blame to Lion Air's maintenance work and its pilots, as well as a Florida firm that supplied a component, according to an advance copy reviewed by The Seattle Times.
"The design and certification of the MCAS (Maneuvering Characteristics Augmentation System) did not adequately consider the likelihood of loss of control of the aircraft," the report states. "A fail-safe design concept and redundant system should have been necessary for the MCAS."
The 362-page report was released Friday in Indonesia, or around midnight Thursday in Seattle.
It was prepared by the National Transportation Safety Committee of Indonesia, known by its Indonesian acronym KNKT, with the support of the U.S. National Transportation Safety Board (NTSB) and the equivalent accident investigation and safety agencies of Australia, Singapore and Malaysia.
Boeing experts, working as technical advisors to the U.S. National Transportation Safety Board, supported the investigation.
