Customer Center Feathering Pumps Aircraft Accessories of Oklahoma handles Aircraft Feathering Pumps from the following manufacturers: Pesco What is an Aircraft Feathering Pump? A basic aircraft feathering system consists of a feathering pump which, in this case, is part of the aircraft prop governor, reservoir, and a feathering time-delay switch. Some aircraft incorporate a feathering indicator light in the cockpit. The aircraft propeller is feathered by moving the control in the cockpit against the low speed stop. This causes the pilot valve lift rod in the aircraft prop governor to hold the pilot valve in the decrease RPM position regardless of the action of the governor flyweights. The aircraft propeller blades then rotate through high pitch to the feathered position. Other aircraft have a separate feathering pump. With this system, depressing the feathering button initiates the feathering. This action energizes a feather solenoid which positions the feathering valve to transfer oil to feather the propeller. When the aircraft propeller has been fully feathered, oil pressure will buildup and operate a pressure cutout switch which will cause the auxiliary pump to stop. Feathering may also be accomplished by pulling the engine emergency shutdown handle or switch to the shutdown position. We overhaul, exchange, repair, and bench check aircraft feathering pumps. An FAA 8130-3 airworthiness certificate is available upon request. Image does not depict any particular model – for reference only. Aircraft Accessories of Oklahoma 2740 N. Sheridan Rd.
