17. The tail brace rods are made from stainless steel rod and are reduced in
diameter toward the threaded ends. The transition area should extend
over approximate 1” to 1.5” and must be smooth. If this area is
NOT
smooth, then modify the tail brace rods as shown in FIGURE 01C-17. The
setup in FIGURE 01C-17 makes the task of filing and polishing easy and
quick. When clamping the rod in the drill, use some plastic or tape around
the end to protect the threads. Use a fine file first and polish afterwards
using Scotch-Brite or fine wet/dry paper. Do not worry the rods are plenty
strong.
18. Install the aluminum bushings into the stabilizer attach bushings on the
fuselage top longerons. See
FIGURE 01C-18 .
19. Attach the stabilizer to the fuselage using the hardware shown in the parts
manual. It may be necessary to hold the stabilizer in a vertical position to
obtain hole alignment. Install cotter pins.
20. Support the stabilizer in horizontal position. Attach jam nuts and tie rod
ends to tail brace rods. Refer to
FIGURE 01C-20 . NOTE: The tail brace
rods have on one end LH and on the other end RH threads. There are
also tie rod ends with LH and RH threads. Assemble accordingly. The LH
and RH threads will make tension adjustment possible without
disassembly.
21. Turn rods all the way into the rod ends. This will assure even thread
engagement at both ends when the rods are turned for final tension
adjustment.
IMPORTANT: For rod tension or length adjustment always
turn the rod and keep both ends fixed. That will assure even thread
engagement on both ends.
22. Attach the pre-assembled rods with clevis pins and cotter pins in the
appropriate positions as per parts manual. When you do so, adjust the
tension of the upper rods so that the lower rods do not bend.
23. For final adjustment, refer to RIGGING .
