Hey Coops,
I had a great program for the Caravan from Cessna themselves, I am not sure I can find it but I will try. But I sure it is a lot cheaper than the rest of your aircraft.
good luck please post what you hear if you can
Since we are talking costs does anyone have an idea what the costs are for a turbo commander, I am sure there a couple of guy from the straits or Carins that would have an idea.
