value give in Table 1. Note that if a new leg is being fitted it will be necessary to check and

8.8.4 INSPECTION AND REPAIR
1.
Inspect composite beam for damage indicated by cracks or de-lamination. Pay particular
attention to the area around the centre bend and to areas around drilled holes.
2.
When inspecting the legs shown in Figure 61 pay particular attention to the area around each
bend in the leg. Note that it is possible for this leg type to have internal damage which does not
show to the surface. In this case the best indicator of the damage is that the damaged leg will
have lost stiffness compared to the other side and so the aircraft will lean in the direction of the
damaged leg. If required, legs can be returned to Jabiru Aircraft for testing.
3.
Inspect bolts and nuts for signs of stress, bending or corrosion
– replace if in any doubt.
4.
Inspect clamp for damage.
5.
Inspect bolt seats in fuselage for signs of damage, wear or perishing.
6.
For the leg shown in Figure 61, inspect the outboard clamp flock bed & re-flock if damaged.
WARNING
Repairs to the composite undercarriage beams must be referred to JABIRU AIRCRAFT Pty Ltd or
our local approved agent.
