8/14/23 - 0.7h 8/15/23 - 2.3h 8/16/23 - 0.2h The objective of this section is to install the aileron control system from the torque tube in each wing root to the aileron bellcrank attached to the main spar about mid-span down the wing (directly above the tie-down location). All of the parts are prepared in the previous sections, including installation of the bellcranks and torque tubes. This step fine-tunes the length of the pushrods using a supplied template to determine the neutral position of the bellcranks and torque tubes. The aileron control system installation starts by temporarily attaching the pushrod to the bellcrank and torque tube in each wing. The W-730 Bellcrank Jig (aka neutral template) is also temporarily attached to the bellcrank to lock it into its neutral position. When the pushrod is attached at each end, both the bellcrank and torque tube should be in the neutral position. If the torque tube is not at neutral, the pushrod gets lengthened or shortened as needed by twisting the rod end bearings in or out until the torque tube is neutral. Once the pushrod is adjusted to the correct length, the jam nuts can be tightened against the rod ends to keep the rod end bearings in the correct position. I waited to do the final torquing of the nuts and bolts for the aileron control system until the entire system was complete and installed. I wasn't sure if I would have to remove the push rods to make other areas accessible, but I wanted the option just in case. As it turns out, I disconnected and reconnected the push rod several times. The plans details for proper installation of the bolts, washers, bushings, and nuts can be a bit confusing. I didn't get it quite right the first time, which is another reason to delay the final application of the torque wrench. The note in the plans to install one washer inside the torque tube clevis arm along with the pushrod rod end bearing and to install the other washer under the nut refers to the two NAS1149F0363P washers on the bolt that attaches the pushrod to the torque tube in the wing root. There are also two NAS1149F0363P washers on the bolt at the bellcrank, but they are both on the outside of the bellcrank under the nut. The other potential area of confusion is the location of the large AN-970-3 washer, which is placed on the bolt between the bushing and the pushrod end.
