Set the aileron cable lengths
Loosen off the lock nuts on the rod ends at both ends of each aileron cable.
Set the control stick so that it is centred laterally/from side to side.
Check that both ailerons are still set to the neutral position and then carefully adjust the rod
ends on each aileron cable by hand so that an AN3 bolt can be fitted though the rod end and
the aileron bellcrank on each side.
It may be necessary to adjust the cable length at both ends of the cable, and ideally the rod
ends should be adjusted to be close to equal with the same amount of thread showing at each
end of the cable. Work on one side at a time and check that the aileron is still neutral and the
stick is still centred, then move to the other side.
Take your time with this step: it is easy to bump the control stick slightly while testing cable
lengths and it may be necessary to repeat the process several times until both ailerons are set
to neutral and the cable lengths are both correct.
Ensure that the inboard end of the aileron cables are connected to the
same side
of the aileron
bellcrank at the rear of the control column: the left wing cable
must
connect to the left side of
the bellcrank and the right wing cable
must
connect to the right side of the bellcrank.
When both aileron cable lengths have been set with the ailerons in the neutral position and the
stick centered, fit the rod ends to the aileron bellcrank with an AN3 bolt. Fit an AN960-515
(1/4”) flat washer, then the rod end followed by an AN960-416 (3/16”) flat washer, then the
bellcrank, another AN960-416 (3/16”) flat washer and a Nyloc nut.
Tighten the Nyloc nuts to safety and mark each nut with a dab of
TorqueSeal
.
Tighten the rod end locknuts at each end of each aileron cable firmly and mark each locknut
with a dab of
TorqueSeal
.
