Authorities in Indonesia told the families of victims of last year's Lion Air crash that systemic design flaws in Boeing's 737 Max contributed to the disaster.
In a meeting led by the Indonesian National Transportation Safety Committee, investigators shared a summary of their final report on the crash. They said Boeing failed to adequately prepare airlines and pilots to handle a new software in the 737 Max, the MCAS, and that MCAS malfunctions ultimately caused Lion Air flight 610 to crash shortly after takeoff.
Indonesian investigators also faulted Lion Air and the flight's pilot and co-pilot, whom they said did not effectively manage the various alerts caused by the malfunctioning system.
Aviation regulators say the MCAS system contributed to both the Lion Air crash and an Ethiopian Airlines crash that occurred just months later. Together, they left 346 people dead. Following the second crash, Boeing's 737 Max aircraft was grounded worldwide.
Boeing's been struggling since then. The company says it's already faced roughly $7 billion in costs related to the grounding. And on Tuesday, Boeing's board ousted Kevin McAllister, the commercial airplanes division chief who had been heading the company's response to the crashes.
The final report from the Indonesian National Transportation Safety Committee is expected to be released on Friday. It has reportedly already been sent to the U.S. National Transportation Safety Board.
