C208 doesn't have its own specific type rating. Although the legislative instrument associated with Part 61 (CASA 186/14 - Prescribed aircraft, ratings and variants for CASR Part 61 Instrument 2014) says you need to undertake initial training and flight review. This can be done by an appropriately qualified flight instructor. What syllabus you follow for this training I'm not sure of. Maybe someone who has knowledge of the new MOS can help.
Do you get a "C208" entry on a Part 61 licence because of schedule 12 of CASA 186/14? I just received my new licence, called CLARC and the person at the other end of the line said you don't. But if you need a flight review for it, shouldn't there be an entry on the licence similar to the one I had on the CAR 5?
