Boeing Knew About 737 Max Sensor Problem Before Plane Crash In Indonesia
Boeing knew that there was a problem with one of the safety features on its 737 Max planes back in 2017 – well before the Lion Air crash in October 2018 and the Ethiopian Airlines crash in March. But it did not disclose the issue to airlines or safety regulators until after the Lion Air plane crashed off the Indonesian coast, killing all 189 aboard.
In a statement Sunday, Boeing said its engineers discovered a problem with a key safety indicator within months of Boeing delivering the first 737 Max planes to airlines. The indicator, called an angle of attack disagree alert, is designed to warn pilots if the plane's sensors are transmitting contradictory data about the direction of the plane's nose.
Boeing intended for the indicator to be standard on the 737 Max, in keeping with the features available on previous generations of 737s. But its engineers discovered that the sensor worked only with a separate, optional safety feature. Boeing said the faulty software was delivered by a vendor, which it didn't name.
