Boeing 737 MAX crash: It says optional alert was 'not activated as intended'
Boeing Co said an alert for angle-of-attack (AOA) sensors on its 737 MAX jets was "not activated as intended" for some customers, responding to reports it failed to tell Southwest Airlines Co and the U.S regulator that the optional feature was deactivated before a crash in Indonesia in October.
Erroneous AOA sensor readings that led to aggressive nose-down inputs by a computer have been linked to deadly 737 MAX crashes in Indonesia and Ethiopia, Boeing said. Image source: Company website
