Task Instructions
1. Use a T20 Torx driver to remove the aft bulkhead baggage panel attach screws. Remove the panel. (Removal and Installation of Inspection Panels and Fairings)
2. Using a flashlight and inspection mirror as required, inspect attachment and integrity of the water actuator, return spring, cables, turnbuckles, and attach points. These parts are located behind the main landing gear bay, near the bottom of the hull. Pay particular attention to any corrosion that may be forming on the steel cables. Any significant visible rust or broken cable fibers are grounds for cable replacement. Apply corrosion inhibiting oil to all cables in the area.
3. Repeat step 2, while having a second person actuate the water rudder to the extended and retracted position. While observing the actuator area, check for freedom of motion of all parts. The return spring should maintain tension on the cable throughout the entire motion. There should be no slack in the cable at any time.
4. While standing outside by the water rudder surface, have a helper move the rudder pedals through their full travel. Check for correct and full motion of the water rudder; it should rotate 40±5° about its steering axis in each direction when corresponding full rudder pedal input is applied. Apply corrosion inhibiting oil to the cables at the front of the rudder.
5. Have the helper extend and retract the rudder while the rudder is checked for smooth and free motion. Verify that the water rudder retracts with its trailing edge within 1inch of the bottom of the hull but does not rub on the hull.
6. Verify that when extended the water rudder surface can be deflected aft by hand, the deflection being allowed, but resisted by the return spring.
7. Re-install the aft baggage panel and retract the water rudder.
Verification Method
The inspection is complete once the task instructions have been performed.
