Doesn't surprise me. The aircraft is designed for point to point biz jetting (although the 300 is a better aircraft). That it does very well, I've flown both and they're very nice For flying training its just not robust enough. King Air with proline 21 is much more suitable (look at the number still being sold for hard grafting jobs)....oh and as for the jayhawk/beechjet/Hawker 400/Mitsubishi Diamond..omg don't go near one of those! Quite possibly the worst designed aircraft I've flown (outflow valve in front of the pilots so all the smoke goes through the flight deck when its evacuated....spoiler for roll control, yaw damping issues the list goes on!)
