A system (300) and method (600) for feathering an aircraft propeller (30) are provided. A first feather solenoid (301) and a second feather solenoid (302) each comprising at least one solenoid coil (311, 321, 312, 322) and a solenoid valve (313, 323) coupled to the actuator (220) and to the at least one solenoid coil (311, 321, 312, 322) are provided. At least one controller (400) is configured to selectively energize and de-energize the at least one solenoid coil (311, 321, 312, 322). The solenoid valve (313) of the first feather solenoid (301) is configured to be activated when the at least one solenoid coil (311, 312) of the first feather solenoid (301) is energized and the solenoid valve (323) of the second feather solenoid (302) is configured to be activated when the at least one solenoid coil (321, 322) of the second feather solenoid (302) is de-energized. The solenoid valve (323) is configured to, when activated, modulate the supply of hydraulic fluid to an actuator (220) for adjusting a blade pitch of the propeller (30) towards a feather position.
