CHICAGO—Boeing Co. said on May 5 that a Safety Review Board convened in late 2018 corroborated its prior conclusion that an angle-of-attack (AOA) sensor on the 737 MAX, which has suffered two fatal crashes, was not necessary for the safe operation of commercial aircraft.
In a statement following a series of negative news reports, Boeing provided greater detail on its recent decision to make the previously optional AOA Disagree alert a standard, standalone feature on the 737 MAX before the grounded jets return to service. The alert lights up when two sensors produce widely different readings.
