Official: Safety Feature Failure Behind ET 302 Crash

ADDIS ABABA – The Ministry of Transport and Logistics has issued its final investigation report faulting safety feature failure for the Boeing 737-8 Max airplane crash.

The report was made official late last week nearly four years after the aircraft flying from Addis Ababa to Nairobi crashed a few minutes after takeoff, killing all 157 passengers and crew on board. 

The ET 302 Boeing 737-8 Max Aircraft Accident Investigation Final Report concluded that the crash was due to safety feature failure.

Transport and Logistics Minister, Dagmawit Moges, stated that the final report confirms that there was nothing wrong before takeoff.

“The airplane’s Left Angle of Attack (AOA) sensor failed immediately after takeoff, sending faulty data to the flight control system. 

The erroneous data, in turn, triggered the Maneuvering Characteristics Augmentation System (MCAS), which repeatedly pitched the nose of the plane down to the point the pilots lost control.”

The angle of attack sensors on the aircraft tells the MCAS to automatically point the nose of the plane down if it is in danger of going into a stall.

MCAS is an automated safety feature on the 737 Max 8 designed to prevent the plane from entering into a stall or losing lift. 

The minister stated that the final report into the March 2019 crash is in line with and builds on the preliminary and interim reports that were released before.

French and US Aviation institutions supported the investigations carried out by the Accident Investigation Bureau in the ministry. The ET 302 Boeing 737-8 Max Aircraft Accident Investigation Final Report will soon be published on the ministry’s website.
