Preliminary findings of the Boeing 737 MAX crash investigation revealed that the anti-stall system of the Boeing 737 Max backfired during the takeoff, which caused the tragic Ethiopian crash.
The investigators came to a preliminary conclusion based on the black boxes of the flight obtained from the crash site. The stall prevention system known as the MCAS [Maneuvering Characteristics Augmentation System] activated automatically preventing the flight from taking off, according to a CNBC report.
The report said that the preliminary findings were subject to review. It also added that U.S. government air-safety experts have been examining details obtained from the Ethiopian investigators.
Ethiopian Airlines Boeing 737 Max Jetliner headed for Nairobi, earlier this month, crashed shortly after takeoff. The crash killed all the people on board. Boeing Co. 737 Max jetliners were grounded for an indefinite period after the incident.
Many argue that the MCAS was responsible for both crashes involving Boeing 737. The MCAS forced the nose of the plane down despite several attempts by the pilots override the system.
The primary crash involving the same Boeing jetliner was the Lion Air flight which crashed into the Java sea shortly after takeoff from Jakarta, killing everyone onboard. According to a Wall Street Journal report, Ethiopian Transport Minister Dagmawit Moges said that data from the plane’s flight data recorder found at Ethiopian crash site showed “a clear similarity” with the Indonesian crash.
On Wednesday, Boeing updated plan’s software, cockpit alerts and pilot training to fix the MCAS. The outline of the fixes will be sent to the Federal Aviation Administration for certification and approval.
