After the RAT (Ram Air Turbine) is deployed on a Falcon 7X aircraft, a hydraulic re-stow pump is used to retract the unit back into the fuselage using task card 24-50-00-910-804.
Duncan Aviation technicians have been noticing light corrosion on the pump piston. We highly recommend you apply a thin coat of MIL-H-5606 hydraulic fluid before final stowage of the unit.
