The US National Transportation Safety Board (NTSB) has released additional comments on the Ethiopian Aircraft Accident Investigation Bureau’s (EAIB) final report of the March 10, 2019, crash of Ethiopian Airlines flight 302, a Boeing 737 MAX 8 aircraft. This is in addition to the previous comments on the EAIB’s final accident report, which detailed the investigation’s insufficient attention to the human performance aspects of the accident. “But the NTSB found the erroneous AOA sensor output was caused by the separation of the AOA sensor vane due to impact with a foreign object, which was most likely a bird. During the accident investigation, the NTSB provided the EAIB with evidence supporting this finding, but that evidence was not included in the final report. “The NTSB also said the EAIB’s finding about the lack of MCAS documentation for flight crews was misleading since Boeing had provided the information to all 737 MAX operators four months before the Ethiopian Airlines crash.”The French BEA has also criticised the Ethiopian crash investigation.
