Why a C90? Curious bystander and have considerable hours watching the operations of B200s from the right seat. Same basic engine design, more power, more seats, more payload, more range, more speed, excellent rough field ops, better cabin environment, better chance of getting one already modded with a cargo door. Why not a B200?
Interesting link Obi_Wan 2015. The guys flying for Norfolk kept prodigious logs on engine condition on every flight. With those cycle numbers and costs involved...it all makes sense now
