The Ethiopian Airlines pilots could not control the plane despite following the protocol of Boeing


A flaw in the flight control system software of the Boeing 737 Max 8 caused the plummeting of the Ethiopian Airlines plane that crashed on March 10 in Ethiopia and killed 157 people, according to the preliminary investigation of the Accident disclosed today by the Ethiopian Government. The pilots of the plane followed all the emergency procedures of the US manufacturer but "could not control" the aircraft, which ended up crashing to the ground, as informed this Thursday the Ethiopian Transport Minister, Dagmawit Moges, in an appearance in the capital.

"The crew met all the manufacturer's procedures repeatedly but could not control the aircraft, "said the minister, who has released the preliminary report on the incident that killed 157 people.

The minister has recommended that Boeing review the aircraft's control system and that authorities confirm that the problem has been resolved before allowing the 737 MAX 8 model to fly again. "Due to the repeated conditions of descent of unordered nose that have been perceived, it is recommended that the control system of the aircraft be reviewed by the manufacturer", said the minister.

In line with international standards on air accidents, the preliminary report is not responsible for the accident or provides a detailed analysis of the flight, since this study will take months until it can be included in the final report. However, the report does make it clear where the investigators have focused their attention, since it rules out that the pilots used incorrect procedures when trying to avoid the accident and, at the same time, gives two recommendations for the manufacturer, Boeing, and the regulators.

First, the report suggests that Boeing review the aircraft's control system and that the aviation authorities confirm that the problem has been resolved before allowing this model of aircraft to fly again. Boeing aircraft of the 737 MAX family remain on the ground as a precautionary measure since the Ethiopian incident, the second recorded with that type of aircraft from which ended the lives of 189 people in October in Indonesia.

The report states that the pilots correctly followed Boeing's emergency procedures but could generate a debate with the manufacturer regarding how to respond to the problems generated by poor sensor measurement that guides the MCAS automatic stabilization system. Boeing has said it will study the report of the Ethiopian authorities. Relatives of the victims of the accident, regulators and travelers from around the world are waiting to know the keys of this plane crash, in which the aircraft crashed to the ground six minutes after taking off. The preliminary report of the accident of the 737 MAX 8 crashed in Indonesia says that the pilots lost control of the plane after having been trying to counter the action of the MCAS system, which automatically lowers the nose of the aircraft when it detects with its sensors that the plane fly more inclined up than it should.
