When Pilatus sold the RFDS on the PC-12, they spent a lot of money to make sure they had the technical and spares support in the country when first airframes arrived and went into service. They also spent a lot of time with the RFDS engineering to get on top of any issues that showed in the first year or so of operation. The Pilatus team knew full well any major issues with the aircraft would definitely cost them future sales to the RFDS and other operaters.
