Aileron Rigging - Jabiru j160 Technical Manual

Aircraft Technical Manual
JTM001-5

The aileron does not have balancing weights fitted. The Aileron used for the J160-C does however
have limits for weight and hinge moment which are applicable to all models using the same aileron
(1215mm nominal length, non-Friese type):
- Weight
- Hinge Moment

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.

For aileron installation, reverse the procedure detailed for removal above.


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.

Check UP travel on both ailerons using the Aileron Rigging Template (Templates can be supplied by
Jabiru Aircraft Pty Ltd)

Use the Aileron Control Stop adjustment on the central control shaft to adjust the total aileron
movement (i.e. UP travel) and use cable adjustment as previously described to proportion UP and
DOWN travel. Note that while it is possible to adjust the Type 3 aileron stops using the eccentrics
using the limit screws shown in Figure 92 is easier.

DO NOT move the Cable Anchors – these positions have been set using a jig.
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.
