Indonesian authorities have cited failures in the Boeing 737 MAX design and oversight as contributing to the 2018 Lion Air plane crash, the Wall Street Journal reported on Sunday. The report into the crash, which will be formally released in early November, also blames pilot error and maintenance issues for the crash that killed 189 people shortly after the flight departed from Jakarta last October, the newspaper said. The Boeing plane model was later grounded worldwide after an Ethiopian Airlines 737 MAX crashed after taking off from Addis Ababa in March, killing 157 people. Preliminary investigations into both accidents have implicated the MCAS anti-stall system, designed specifically for the 737 MAX. Indonesian investigators could still change their findings, which have been shared with the US Federal Aviation Administration (FAA) and National Transportation Safety Board (NTSB), the Journal said. US officials are scheduled to visit Indonesia at the end of September to discuss the report, in which Indonesian investigators list some 100 factors in the crash.
