Small Cog
Unanticipated fail modes leading to cascading failures can occur but I would suggest that historically the record shows most of them were exacerbated by inappropriate crew actions. It will be interesting to see the official report on this incident.
Like I said above when the only thing on the PFD and MFD is the makers name, a good outcome is going to depend on the basic flying skills of the crew, something this crew obviously had but sadly is no longer a given on modern flight decks
