The cause of the Ethiopian Airlines crash which killed 157 people has been revealed, according to reports.
It is believed the Boeing 737 Max suffered a damaged ‘angle-of-attack’ sensor upon takeoff from a foreign object which could have been a bird, ABC News reports.
This reportedly triggered erroneous data and the activation of an anti-stall system that sent the plane down on March 10 shortly after take off from Addis Ababa.
Boeing anti-stall software on the doomed jet re-engaged and pushed the jet downwards after the pilots initially turned it off due to suspect data from an airflow sensor, two sources said.
It was not immediately clear whether the crew intentionally re-deployed the MCAS system, which was designed to push the nose of the 737 MAX down to prevent a stall.
The pilots were not able to get control of the plane back, sources told ABC News.
Passengers from more than 30 nations were on board the aircraft.
The reports come hours before preliminary findings of an investigation into the crash by Ethiopian officials on Thursday.
