"French and American investigators are assisting in the Ethiopian probe and at the center of it is an automated anti-stall safety system on the MAX and its possible link to issues in the Ethiopian flight and a Lion Air crash in 2018.In both crashes, the Boeing 737 MAX aircraft struggled to maintain a steady flight path. The planes repeatedly lost and gained altitude before entering a dive to the earth's surface. In the two incidents, a new anti-stall safety system on the MAX that controls trim -- MCAS -- was activated, sources have told ABC News.Commercial airline pilots are trained to disengage the system in the event of runaway trim, when the airplane is making unexpected pitch movements. It is unknown what would have kept the pilots of the Lion Air flight from disengaging the system and trimming the aircraft. Lion Air has defended the training of its pilots.In the days following the crash of Ethiopian Airlines Flight 302, airlines and aviation authorities around the world grounded the MAX.
