Calls and messages outside regular working hours to Ethiopian investigators at the Ethiopian Civil Aviation Authority and Transport Ministry seeking comments were not immediately answered. The crash followed another fatal 737 Max crash in Indonesia less than five months earlier and led to regulators grounding the model worldwide, plunging Boeing into crisis. China, a major market for Boeing, still has safety concerns and said this month it’s awaiting conclusions from the Ethiopia probe. There’s little doubt that Boeing’s design of a flight-control feature known as Maneuvering Characteristics Augmentation System will be at the center of the cause of the Ethiopian crash. The Ethiopian pilots followed the same steps initially, but reactivated MCAS and lost control, according to preliminary data.
