Checked aileron travel, noted unevenness*. Readjusted both control arms to achieve specified deflections (22 up, 14 down) as close as possible for both left and right, when aileron bellcranks are at stops. Then locked yokes and adjusted turnbuckles to bring ailerons into alignment with wing trailing edges. Had to remove left wing aft turnbuckle and run it in and out with drill to get free movement.
Installed nut on right wing aileron control bolt and tightened. This was very time consuming due to difficult location of bolt and nut. Eventually arrived at a combination of tools to get the job done. See photo. Then upon tool removal dropped loose Phillips bit into the innards of the aileron. Or so I think. Unable to locate it with flashlight, mirrors, or magnets. Will try borescope next time out.
Left side control arm bolt/nut still to be installed. Then final tweaking of aileron positions and cable tensioning must be done before safety wiring the three turnbuckles.
*Part of the problem was that while the Cessna documents say the cable bolt to wing rib distance is 2 17/32”, that is only true for the left wing of our airplane. The distance in the right wing in our airplane is 2 5/8”. That caused a lot of confusion until the discrepancy was discovered.
Ratchet and 3/8 socket left. Loose Phillips bit and vice grips right.
