Investigators said that mechanical and design issues were blamed for the crash. Contributing factors to the crash of the new Boeing jet, which killed all 189 on board, included incorrect assumptions on how an anti-stall device called the Maneuvering
Characteristics Augmentation System (MCAS) functioned and how pilots would react.
The briefing slides showed that a lack of documentation about how systems would behave in a crash scenario, including the activation of a "stick shaker" device that warned pilots of a dangerous loss of lift, also contributed, Reuters reported.
"Deficiencies" in the flight crew's communication and manual control of the aircraft contributed as well, the slides showed, as did alerts and distractions in the cockpit.
Reliance on a single angle-of-attack sensor made MCAS more vulnerable to failure, while the sensor on the plane that crashed had been miscalibrated during an earlier repair, according to the slides.
The 737 MAX was grounded worldwide after a second deadly crash in Ethiopia. The manufacturer faces nearly 100 lawsuits over the Ethiopian Airlines crash on March 10, which killed all 157 people on board the flight from Addis Ababa to Nairobi.
Boeing last month settled the first claims stemming from the Lion Air crash. Three other sources told Reuters the families of those killed will receive at least 1.2 million USD each
Indonesia media have said the report could be released as early as October 25./.
