Tbm is an awesome machine and I dont think I personally would have an issue flying it. As Midland says though there could be duty of care implications towards any employees.
The biggest downside of the TBM I feel is the price. For something with one engine, and essentially light aircraft avionics why does it cost upwards of what a C90gti comes in at, with double the number of engines and serious avionics? Up until now it didn't even have the glass cockpit.
Perhaps the King air 90 or 200 would be better suited. Certainly if you plan on carrying more than two or three pax they knock spots off a Mustang for range/payload etc.
