Just before the end of the year, Ethiopian investigators published their final report on the crash of Ethiopian Airlines flight ET302. Flight 302 crashed shortly after takeoff from Addis Ababa Bole Airport on 10 March 2019. Operated by Boeing 737-8 MAX ET-AVJ, it was the second crash of a 737 MAX in just over four months and led to a worldwide 20 month grounding of the MAX while Boeing and regulators made changes to the aircraft.

Following the publication of the final report, both the US National Transportation Safety Board (NTSB) and French Bureau d’Enquêtes et d’Analyses (BEA) took the highly unusual step of publishing separate comments on the report.
Ethiopian investigators’ probable cause: MCAS

In their final report, Ethiopian investigators solely focus on the activation of the Maneuvering Characteristics Augmentation System as the probable cause of the accident.
