The Accident Investigation Bureau today issued a preliminary report on the accident of the Boeing 737 MAX 8 operating flight ET302 on 10 March 2019. Here is its Executive Summary:
On March 10, 2019, at 05:38 UTC, Ethiopian Airlines flight 302, Boeing 737-8(MAX), ET-AVJ, took off from Addis Ababa Bole Int. Airport bound to Nairobi, Kenya Jomo Kenyatta Int. Airport. Shortly after takeoff, the Angle of Attack sensor recorded value became erroneous and the left stick shaker activated and remained active until near the end of the flight. In addition, the airspeed and altitude values from the left air data system began deviating from the corresponding right side values. Due to flight control problems, the Captain was unable to maintain the flight path and requested to return back to the departure airport. The crew lost control of the aircraft which crashed at 05:44 UTC 28 NM South East of Addis Ababa near Ejere village.
Ethiopian Airlines Aviation Group acknowledges the preliminary report of the accident of ET302/10 March 2019 (available here as pdf) and appreciates the hard work of the investigation team.
The preliminary report clearly showed that the Ethiopian Airlines Pilots who were commanding Flight ET 302/10 March have followed the Boeing recommended and FAA approved emergency procedures to handle the most difficult emergency situation created on the aeroplane. Despite their hard work and full compliance with the emergency procedures, it was very unfortunate that they could not recover the aeroplane from the persistence of nose diving. As the investigation continues with more detailed analysis, as usual, we will continue with our full cooperation with the investigation team.
Group CEO, Tewolde GebreMariam said that “All of us at Ethiopian Airlines are still going through deep mourning for the loss of our loved ones and we would like to express our deep sympathy and condolences for the families, relatives and friends of the victims. Meanwhile, we are very proud of our pilots’ compliances to follow the emergency procedures and a high level of professional performances in such extremely difficult situations. We are also very proud of our Global standard Pilot Training Center and the Ethiopian Aviation Academy which is one of the largest and most modern in the world equipped with state of the art and latest training technologies. I would also like to take this opportunity to thank our valued customers, the travelling public, the media and Global aviation professionals for the remarkably high level of votes of confidence and strong support that you have been giving us starting from the day of this tragic accident. We will double our efforts every single day to win your confidence and earn your business. Your safety will remain our top most priority and we will continue to work together with our partners around the world to make air travel safer and more comfortable. My highest appreciation also goes to my 16, 000 colleagues at Ethiopian Airlines for their resilience, high standards of professionalism and their continued commitment for operational excellence and their award-winning customer services which enabled us to continue our business without any operational disruption, flight delays or flight cancellations.”
