Task Instructions
1. Remove Aft Bulkhead Baggage Panel (Removal and Installation of Inspection Panels and Fairings) to allow access to the water rudder actuator, extension spring, and connected cables.
2. Use adhesive tape to attach a piece of string, about 8 ft long, to each water rudder cable, just aft of the swage sleeves. These strings will be used to pull the new cables through the correct path. Label the string connected to the actuator “A” and string connected to the spring end “S”.
3. Use a cable cutter to cleanly cut the two water rudder actuation cables at a point just aft of the swaged sleeves.
4. Remove the extension turnbuckle assembly by removing the clevis pin that passes through its forward eye.
5. Remove the retraction turnbuckle assembly by removing the clevis pin that passes through its forward eye.
6. Remove the remnants of cable, sleeve, and thimble from the aft ends of both turnbuckle assemblies with a cable cutter.
7. Remove the water rudder inspection panel.
8. Remove the two MS24694C56 screws that hold the bottom water rudder hinge tang to the hull.
9. Pull the water rudder assembly down and out of the hull. Doing so, will also pull the actuation cables, so be careful and guide the cables and strings aft and through the pulleys above the water rudder bellcrank. Once the strings are through and aft of the pulleys, remove them from the cables and secure them with tape to the internal structure for use during cable installation.
10. Pull the cables the rest of the way through the hull fitting and free of the aircraft.
11. Remove the binding post hardware at the extension pivot of the water rudder and separate the rudder from the pivot flange assembly (the carbon yoke piece that holds the rudder).
12. Withdraw the cable from the pivot flange assembly.
13. Remove the ICA008934 Pivot Bushing from the water rudder.
14. Remove the two flush-head MS24694C53 screws that attach the cable puck to the water rudder, then remove two M81934/2-05C012 bearings from either side of water rudder.
15. Pull the puck and cable from the rudder.
16. Using a punch, remove the cable retaining pin 97855A510 from puck.
17. Remove the cable from the puck by disengaging the swaged bull from the notch in the puck.
18. Discard the old cable and clean all parts.
Verification Method
Confirm old cables are removed and parts are clean.
