Aside from the safety aspect of turbine engines in the 406, lets not forget about the cost of avgas.Up north it is often 3 times the price of jetA1, thats if you can get it in the first place.
Fugros decision to get rid of the 404 with its GTSIO 520 Engines was a good one and i don't think it had anything to do with oil companies
requirements.
