To the best of my knowledge the accident of a Crossair Saab 340 in Nassenwil near Zurich, Switzerland, was due to a eastern pilot as PF and a different design of the eastern and western artificial horizons.
Having read the transcript and watched the video where any correction of "Bank Angle" warnings lead to even steeper turns make one think of the artificial horizon.
Read with interest the previous posters comments about CRM during training - and what about the alcohol ?
