A propeller pitch control system for a turboprop engine of an aircraft includes a negative torque sensor (108), a full feather control valve assembly (110), and a feather valve assembly (112). The feather valve assembly (112) is responsive to fluid pressures from the negative torque sensor (108) and the control valve assembly (110) to move between a plurality of positions. An engine control unit or a manual user interface can also be used to control the position of the feather.
