Correct- PT-6 engines (e.g. T-6, T-44, C-12, T-54) have a free power turbine, so they are governed differently from the E-2, C-2, and P-3 single-shaft engines.
Checks that no other pt6 equipped aircraft operator does...Overspeed governor and before takeoff checks, training command style (slowly and deliberately).
Pedantic trivia warning: Pitch lock is not a thing on the T-6, and you can only feather the prop when the motor is shut down (unless the hub loses oil pressure). It’s very quick to check the system- can even be done on the roll. The airplane doesn’t “need” any time in the runup area, but it’s good training for new pilots.
Pitch lock is not a "thing" on the PT6, but KA pilots do feather and autofeather checks, at least they're supposed to...
