Well, I do understand the confusion by many...
That word "turbine" is a very bad name for explanations.
xxx
Jet engines have a turbine as powerplant... and so do turboprops.
FAA requires a type rating for flying any jet airplane.
But a turboprop is... a propeller engine (powered by a turbine, yes).
But only require a check-out as they are over 200 hp.
FAA does not say anything about type ratings for "turbine engines".

A propeller airplane (reciprocating engine or turboprop) fly about the same.
Plenty of power with a turboprop, is the only difference.
But such airplanes behave about the same.
xxx
Jets (turbojet or turbofan airplanes) behave differently from propeller planes.
Therefore, FAA considered it should be requiring a type rating.

Example of handling differences -
On a jet, reducing power does not reduce the "drag" much.
On a "turboprop", reducing power immediately brings propeller drag.
Compare also stall speeds power ON and power OFF.
Basically NO difference for jet airplanes.
Not so for propeller or turboprop airplanes.

Hope you guys all are happy now.
Happy contrails.
