The system designed to down the plane's nose, when it reaches beyond normal angles of attack, is one of the main suspected reasons that led to the two crashes of 737 MAX planes over the last half a year. © REUTERS / Joshua Roberts US Transportation Dept ‘Special Committee’ to Review Boeing 737 MAX CertificateDuring the simulation, the system would constantly kick in, pushing the plane's nose down for 10 seconds and then making 5 second pauses, as was intended. In this way the plane would inevitably crash within 40 seconds once the system kicked in for the first time, the sources indicated. According to the NYT, prior to the Lion Air crash both Boeing and regulators didn't even bother notifying the pilots about the system, which appeared only in the newer MAX jets, considering it unnecessary. The questions about the 737 MAX's anti-stalling system arose after two planes of the series crashed within 5 months soon after taking off.
