that the cables were tightened evenly, check the forward sector rig pin hole to see if the rig pin can be inserted through the sector and into the structure. If this is not possible, then the cables must be adjusted by loosening one and tightening the other. This will maintain the correct tension on the cables, and, at the same time, rotate the forward sector to the neutral position. The cable section is properly rigged when it is possible to insert and remove the forward sector rig pin easily with the aft sector pin installed and the cables tightened to the prescribed tension. The push-pull rod connecting the forward sector and the bell crank is adjusted to the correct length by installing a rig pin in the bell crank. Then, the rod adjustable eye is turned in or out until the rod can be installed between the sector and bell crank without binding. At this point three rig pins are in place, and should remain in place until the control sticks are rigged to neutral. When you are positioning the control sticks to neutral, the rear stick must be adjusted first. Remember, we are working forward from the elevator surface. The push-pull rod connecting the bottom of the rear stick with the bell crank must be adjusted until the stick center line is the prescribed number of degrees forward of a vertical reference line. See the vertical reference line (14) and the center line (15) in figure 9-26. The vertical reference line is a position that the center line of the control stick would attain at a 90-degree angle (19) to the cockpit floor (20). Adjust the length of the push-pull tube between the control sticks to position the front control stick to an angle identical to that of the aft control stick. Then, remove all three rig pins.   This completes the rigging and adjusting of the control system to neutral. All that remains is to adjust the stops that limit the fore and aft Figure 9-27.—Elevator rigging fixture. travel of the control sticks, and rig and adjust the bungee that holds the system in the neutral position. The stop bolts (2) (fig. 9-26) are located in front and behind the aft control stick. They are installed so that the stick hits the stop bolts at the extreme limits of its travel. The maximum travel of the elevators in each direction is determined by the manufacturer and is controlled by the stop bolts. With the rigging fixture still in place, move the control stick all the way forward, and adjust the stop until the elevator DOWN throw conforms to the MIM. Pull the stick all the way aft, and adjust the aft stop bolt to obtain the correct elevator UP throw. The stop bolts are safety wired in place after this adjustment. The last item to be adjusted in this control system is the centering bungee. Connect the bungee and adjust its rod end so that with the stick against the stop bolt in the full down elevator position, the bungee is a minimum of 1/32 of an inch from bottoming. After this adjustment, the elevators should be held in neutral (plus or minus the prescribed number of degrees) by bungee action. If the elevators are too high, shorten the bungee rod end. If they are too low, lengthen the bungee. With the bungee properly adjusted, tighten the bungee rod end locknut and safety wire it. CABLE FABRICATION Control cables are fabricated mostly of extra flexible, preformed, corrosion-resistant steel. Control cables vary from 1/16 to 3/8 inch in diameter. Cables of 1/8 inch and larger are composed of 7 strands of 19 wires each. Cables 1/16 and 3/32 inch in diameter are composed of 7 strands of 7 wires each. Cable-Cutting Equipment Cutting cables may be accomplished by any convenient method except an oxyacetylene cutting torch. The method of cutting usually depends upon the tools and machines available. If a cable tends to unravel, the ends may be sweat soldered or wrapped with a strip of tape prior to cutting. Small diameter cable may be cut satisfactorily with a pair of heavy-duty diagonal cutters, side cutters, or a pair of wire nippers. Best results are obtained if the cutting jaws are held perpendicular to the cable during the cutting operation. Cables up to 3/32 of an inch in diameter may be cut in one operation by this method. Larger cables may require two or more cuts. When you cut large diameter 9-33
