KATLPAX there is nothing wrong with commenting upon the lack of CRM and cultural behaviour providing you keep an open mind to the fact that similar accidents happen in western cultures due to the same lack of CRM and similar cultural (national and operational) behaviours.
Blackmail poses a plausible scenario, but I would prefer to wait for the experts opinion. Particularly with respect to any control input after autopilot disconnect – who made them and why. Also, if the vertical gyros have been recovered what was their condition.
Training is a solution for problems that have already been defined; we do not know the specific problem that lead to this accident.
If the problem was lack of awareness of autopilot status then the training need could be to focus on an instrument scan – what is the aircraft doing.
If the problem was an error in the ADI then operators need to look very carefully at how to train crews to deal with misleading instrument indications; again an issue relating to instrument scan.
