The airstairs are manually lowered but require pressure in the Yellow Hydraulic System to retract. To increase pressure in the Yellow hydraulic system, turn on the AC Pump on the overhead panel and confirm that an increase in Yellow system pressure is observed. With pressure in the Yellow Hydraulic System, the airstairs can be retracted via the controls on the EFB/Tablet.
Why do the airstairs not retract?
