Turbines are at least 10x (might be 50x) as reliable as a piston which might be important some day….
Here in Alaska a busy 135 operator with 10 airplanes might fly 10,000hrs in a year, or more. You would expect piston engine failures fairly frequently. People are converting beavers and otters to turbines and they are doing it to make money. I even saw a tricycle gear Beach 18 with turbines recently.
