Industry sources caution that the MCAS upgrade does not point to a cause of the Ethiopian crash, something Muilenburg's statement also indicated. The two planes experienced similarly erratic steep climbs and descents and fluctuating airspeeds before crashing shortly after takeoff.The 737 Max 8 and 9 have been grounded worldwide since the Ethiopia crash.
According to the flight data recorder, the pilots of Lion Air Flight 610 struggled to control the aircraft as the automated MCAS system repeatedly pushed the plane's nose down following takeoff.
