Disaster was second in five months for U.S. planemaker
Pilots commanding a doomed Ethiopian Airlines jet were hit with a cascade of malfunctions and alarms seconds after the Boeing Co. 737 Max took off from Addis Ababa on March 10, according to a preliminary reportreleased Thursday.
Most critically, the plane’s automatic anti-stall system that was also linked to a previous 737 Max crash months earlier began pushing the nose of the jetliner down less than two minutes into the flight due to a malfunctioning sensor. The crew was able to climb as high as 13,400 feet and request permission to return to the airport after temporarily disabling part of the system.
