The agency was also reluctant to ground the planes after the Ethiopian Airlines crash and was among the last agencies to do so. The Ethiopian officials did not say whether the MCAS system activated because of a faulty sensor that measures the plane’s angle relative to the wind. One of the sensors, called Angle of Attack, malfunctioned in the Lion Air crash, triggering the MCAS system. The question is whether the Boeing 737 Max should have been grounded after the Lion Air crash and before the Ethiopian Airlines crash,” said Hasse. He also would like to know at what point the MCAS system was turned back on and if it was too late to prevent the crash.
