We have written previously about the circumstances that led to the deadly Ethiopian Airlines and Lion Air Boeing (NYSE:BA) 737-Max crashes. The feature in question was supposed to trigger when the aircraft’s "angle of attack vane" sensors began to malfunction. The same report by the Wall Street Journal said regulators discussed grounding all 737-Max aircraft until the problem had been resolved. Supposedly, a small number of FAA inspectors had raised concerns about the angle of attack sensors, but these never made their way up the chain of command. Had these voices been listened to, there is a very good chance the Ethiopian Airlines crash could have been avoided.
