May I suggest that the overall diagram be labeled for a single-shaft turboprop (T56, 250, TPE331 etc.) as opposed to a free-turbine two-shaft machine (PT6, T64, CT7, PW100 series...)
The chief difference will be at shutdown, where the prop on a free-turbine engine will slew to feathered, and not flat-pitch, condition.
(Notable exception: for a floatplane/seaplane installation, the free-turbine prop may be held in flat pitch, to prevent it from cycling through the forward-thrust range during startup, which would present handling issues...)
