7.4.3 AILERON BALANCING
The aileron does not have balancing weights fitted. The control does however have limits
for weight and hinge moment:
Weight
1150g +/- 100g
Hinge Moment 94000g.mm +/- 4000g.mm
The aileron balance is checked at the factory during assembly and unless they are
repaired or refinished the balance should not change.
To balance the ailerons they must be removed from the aircraft. Balancing is done around
the hinges with the hinge pin line horizontal and on the high side of the ailerons. The
hinge moments can be measured by measuring the upwards force needed to maintain the
flat side of the aileron horizontal. Note that as this load is small, a finely graduated spring
balance or similar measuring instrument will be required.
7.5 CONTROL RIGGING
1. With the control stick in the neutral position, use a straight-edge not less than 1
metre long. Hold the straight-edge flush on the underside of the wing aerofoil and
adjust aileron to sit on the straight-edge. Make this adjustment with the cable rod-
ends, ensuring that on completion the locknut is tight on the rod-ends and that
cable is visible through the inspection hole in the rod-end.
2.
Check UP travel on both ailerons using the Aileron Rigging Template (see
Appendix 3).
3.
Use the Aileron Control Stop adjustment (see Figure 23) to adjust the total aileron
movement (ie. UP travel) and use cable adjustment as previously described to
proportion UP and DOWN travel. The Aileron Control Stop should engage before
the Aileron Arm hits the UP travel stop at the Wing Tip.
4.
DO NOT move the Cable Anchors – these positions have been set using a jig.
WARNING
The control cable must be connected to the same side of the control column
bellcrank as the wing to which the aileron is fitted, otherwise control surface
reversal will result.
DO NOT CROSS CABLES
