Perhaps that is what you meant, but it is not what you said.
You said; "The MU-2 has the highest accident rate, highest fatal accident rate of any other type of turbo-prop in its class. That's a fact."
"Class" would be multi engine" "Multi" means more than one, as in 2, 3, and yes, 4.
However the point of your latest post is taken. And as for the -6 being an "airliner"
