Sunfish the problem with the 737 MAX is that no pilots, Western or otherwise, were told about the MCAS system. The 737 is not a FBW aircraft. It has traditional control cables connecting the control columns and rudder pedals to the flight controls with hydraulic systems to assist. The MCAS is a digital solution with connections to the stab to counter an aerodynamic issue. So the idea that they trusted the Boeing manuals and training system more than Western pilots is wrong as even the Western pilots would have been overwhelmed by all the warnings and noises activating if they had encountered an MCAS responding to false information from a single damaged AofA vane. Boeing did not want pilots , airlines or the FAA to know about MCAS as it would have required additional sim training as a minimum and re certification as the WCS. If you want an example of how Western pilots from a legacy carrier have coped with conflicting systems warnings which resulted in a hull loss then check out all the discussion on AF447. To head off any idea that it was all an Airbus problem also checkout the EK777 hull loss in Dubai.
