Boeing system triggered repeatedly in Ethiopian crash, according to sources by byEricMJohnson and Tim Hepher
Although aircraft experts say MCAS cannot turn back on by itself, the report is expected to shed light on whether and why the crew chose to restore electrical power to the system at the risk of setting off more automated nose-down movements.
The pilots maneuvered the plane upwards at least two times before hitting the stabilizer cut-out switches to disable the system, one person familiar with the matter said. In a statement, Boeing said: “We urge caution against speculating and drawing conclusions on the findings prior to the release of the flight data and the preliminary report.”
Getting the planes flying again depends partly on the role that Boeing design features are found to have played in the crash, though investigators are also paying attention to airline operations, crew actions and regulatory measures.
