A system (300) and method for feathering an aircraft propeller (30) are provided. The aircraft propeller (30) is coupled to an actuator (220) for setting a blade pitch of the propeller (30). The blade pitch is controlled by modulating a supply of hydraulic fluid to the actuator (220). At least one feather solenoid (320) is provided that comprises a first solenoid coil (321), a second solenoid coil (322), and a solenoid valve (323) coupled to the actuator (220) and to the first and the second solenoid coils (321, 322). At least one controller (400) is configured to selectively energize and de-energize the first and the second solenoid coils (321, 322). The solenoid valve (323) is configured to be activated when the first solenoid coil (321) and the second solenoid coil (322) are de-energized and to, when activated, modulate the supply of hydraulic fluid to the actuator (220) for adjusting the blade pitch of the propeller (30) towards a feather position.
