Boeing has admitted publicly that a key sensor malfunctioned on the Ethiopian Airlines crash and the Lion Air crash in Indonesia.
The airline pilots “repeatedly” followed the correct procedures that Boeing recommends, according to the first official report.
Boeing chief executive Dennis Muilenburg said: “It is apparent that in both flights the manoeuvring characteristics augmentation system, known as MCAS, activated in response to erroneous angle of attack information.”
The US owned plane maker said, “to ensure unintended MCAS activation will not occur again” they are to release a software update and roll out pilot training for the 737 MAX aircraft.
The Boeing boss apologised and said, “We at Boeing are sorry for the lives lost in the recent 737 Max accidents.”
