Researchers believe that the stabilization system was activated before the Boeing incident in Ethiopia

Investigators analyzing the loss of the Boeing 737 MAX 8 plane from Ethiopian Airlines that killed 157 people near Addis Ababa on March 10 have reached the preliminary conclusion that the automatic stabilization system (MCAS) in English) was activated before the aircraft crashed to the ground, as reported on Friday the newspaper ‘The Wall Street Journal’, citing sources familiar with the inquiries.

The newspaper has indicated that the preliminary conclusions after the analysis of the two ‘black boxes’ of flight ET302 are still subject to possible revisions and that the report of the Ethiopian researchers will be published in the coming days.

The researchers who analyzed the accident in which another Boeing 737 MAX aircraft of Lion Air crashed into the Java Sea in October 2018 causing the death of 189 people also focused their conclusions on the automatic stabilization system of this model of the aeronautical manufacturer U.S.

On Wednesday, Boeing announced that it plans to carry out a software upgrade to prevent the automatic stabilization system from operating repeatedly, as it is believed could have happened in the two fatal crashes that this aircraft has had.

The 737 MAX, the Boeing model with the highest volume of sales in less time, has orders worth more than 500 million dollars but at the moment it is on land by decision of the Federal Aviation Agency of the United States (FAA) although airlines can move them without passengers between airports.
