d) Check the neutral positions and operation of the ailerons.
Ensure that the stick is kept central whilst adjusting the ailerons.
The ailerons should be set with their trailing edges level with those of
the flaps.
Check that the aileron upward movements are around 25 using a
protractor. The downwards movement is less, due to the differential
built into the system.
If necessary, restrict the movement by increasing the diameter of the
stops at the torque-tube horn, using tape around the tube to pad-out the
stops.
e) Check the tension in the aileron cables.
Pulling the overhead cable rearwards to contact the wing covering
tensioner tubes should require a pull of 3kg, plus or minus about 0.3kg.
This will result in the overhead cable resting on the tubes in the wing
roots, but being clear of the tubes at the jury strut attachment locations.
Tension will be felt as the cable is pulled rearwards to around the
location of the colour change on the wing upper-surface.
f) If there is any remaining friction in the aileron control circuit, the fit of the
aileron hinges must be checked.
The ailerons should drop freely under their own weight with the cables
detached. If any friction is felt then remove the aileron eyebolt hinges
and file the holes in the aileron leading edges until the ailerons move
freely. This will greatly improve the feel of the aileron controls.
A very small touch of oil on the hinges works wonders, but not too
much otherwise it will stain the coverings where it blows off.
g) Ensure that the tubes which the aileron cables touch are protected by
oversized pieces of prop tape or similar.
h) Check the neutral position and operation of the elevator.
The elevator should be horizontal with the stick at 90 to the central
cabin tubes, not vertical.
Elevator movement should be 25 each way. If necessary file the stop
positions on the stick pivot piece to increase movement.
i) Ensure the rudder-stop cables have been properly crimped and fitted.
j) Check the neutral position and operation of the rudder and nose-wheel.
With the rudder straight, the nose-wheel should be straight. Rudder
movement should be 25 each way. Nose-wheel movement should be
symmetrical each way.
k) Wire-lock all turnbuckles.
l) Check the correct operation of the brakes.
