Aug 19, 2023 3.5 OP-38-02 - Aileron Trim Brackets Category: Controls
Initial Prep (Debur, Trim, Drill, and Cut)
8/16/23 - 0.5h
8/18/23 - 1.4h
The aileron trim system starts with two brackets, eight trim links, and the trim arm. The brackets and trim links are all final drilled #30, and then each part needs to be deburred for final assembly.

Prime
8/18/23 - 0.7h
Priming the parts followed my standard process of cleaning, scruffing, degreasing, and then priming. The trim links were a little tricky to prime because they are so light that the primer spray blew them off the table! I eventually managed to get the trim links back under control and primed.

Assemble
8/19/23 - 0.9h
The first assembly step sandwiches six trim links and the trim arm between the two brackets. I found that cleco clamps between the rivet holes on the trim links did a good job holding the parts tightly together. I also inserted the trim arm with its washers and clevis bolts before riveting the parts together. You could probably insert the trim arm after riveting, but I think the washers would be difficult to install in that tight space. It was a little cumbersome keeping everything together before riveting, but doable. After the riveting was finished, I used a needle-nosed pliers and small side cutters to finish off the clevis pin.
