From what I remember from working on the Saudi 412's (was a while ago!!), they aren't fitted with a true FADEC, but rather DEC . Single channel, with manual backup, hence not Full Authority (just like the AW139).
I think we called them 412EP+, but I think they're real name is 412SAR. Can't remember. Training notes don't really say what the model designation is (not mine anyway).
Can't really remember much else. It was all a bad dream!!
They hadn't finished delivering them all before I left
