The fatal accident near Addis Ababa came after a Lion Air 737 MAX 8 crashed last October, killing 189 people.
Both major Canadian airlines relied heavily on the 737 Max planes, and warned the groundings would cause delays and disruptions as they deployed other aircraft. Shortly after their takeoffs, both crews tried to return to the airports but crashed.
Boeing, in its turn, said on Wednesday that it had "full confidence" in the safety of its 737 MAX aircraft but supported the decision to temporarily ground the entire fleet of 737 MAX 8 and 737 MAX 9 series planes after the crash. Engineers are making changes to the system created to prevent an aerodynamic stall if sensors detect that the jet's nose is pointed too high and its speed is too slow.
In two anonymous reports on flights just after the Lion Air disaster, U.S. pilots disconnected the autopilot and corrected the plane's trajectory in response.
