There was the IPTN N-250, a very ambitious Indonesian designed fully fly-by-wire turboprop. Apparently in case of FBW failure it had mechanical back up for aileron and elevators, standby FBW for the rudder. Roll spoilers and flaps were also FBW.
Only the prototype flew. The project was put on hold as a condition of World Bank aid.
The glass isn't half empty, or half full, it's twice as big as it needs to be.
