Rigging System
The gas strut is normally maintenance-free, but lubricate pivots occasionally. Do not subject to side-loads.
12.4. LUBRICATION
Trike
The rear steering bar, foot throttle, hand throttle and choke lever pivots should be lubricated with machine oil
weekly. Lubricate the rear suspension sliders with grease as in the following schedule. To do this you will need
to dismantle each suspension leg in turn as follows:
1. Remove wing from trike & place a jack under the keel towards the rear using soft wood to prevent damage.
2. Lift the trike until the weight is just off 1 wheel and support it so that the trike cannot topple when the
suspension leg is dismantled, if possible tie the pylon up to a roof beam.
3. Disconnect bolt attaching lower suspension leg attachment eye, remove 2 socket screws near top of
suspension leg.
4. Withdraw the lower suspension leg, leaving the top section attached to the trike.
5. Loosen the locknut at the top of the upper suspension rod & remove the upper suspension rod using a tommy
bar to unscrew it.
6. Apply grease liberally to the sliders.
7. Reassemble in the reverse order, use Loctite 221 engineering adhesive on the upper suspension rod threads
and locknut and also on the two socket head screws.
8. Repeat the operation on the other leg.
All other bearings are life sealed and require no additional lubrication.
Make sure the aircraft is properly secured and clear of persons and animals
before running this test.
See Section 1.8. PREPARATION FOR SAFE MICROLIGHT/ MICROLIGHT
AIRCRAFT OPERATION, Special Hazards, “Running Up and Testing an
Engine on the G
round”.
When dismantling the suspension legs to
lubricate the sliders it is essential that the trike is
supported to ensure that it cannot topple over.
Failure to do so could result in injury or death.
Gas under high pressure. Do not attempt to
pierce, re-pressurise or incinerate.
It is essential that when re-assembling the suspension legs as in 10 above, you use Loctite
221 as indicated. It is better to use too much and wipe away any excess than to use too
little, so apply it liberally to ensure that all the applicable threaded area is coated. Follow
the instructions on the Loctite container. Failure to carry out this procedure could result in
the undercarriage failing leading to injury or death.
