Boeing failed to communicate with 737 Max operators new procedures for addressing cases in which the airplane’s automatic stall prevention system commands the nose of the airplane downward, potentially resulting the kind of steep dive that appears to have led to the fatal crash of Lion Air Flight 610, according to pilot union officials quoted by the Wall Street Journal.
