Actually, Notso, the rudder on the 340 is purely mechanical (although yaw damping and trim is electric.) It's there as a Mechanical Backup in the event of failure of all flight control computers.
Sky Wave - I haven't read the FI article (and if it's in FI then it must be true, mustn't it.....?) but it would mean a large-scale redesign of the flight control system, and I wouldn't have thought they'd do that half way through the type's life.
