Ensure nuts are not thread-bound (i.e. the thread on the nut has hit the end of the thread on the bolt.
All spherical bearings must be fitted with a large washer on the outside of the through-bolt to prevent
the bearing case and cable releasing in the event of a bearing failure.
i.e. a ¼” washer must be fitted
to 3/16” bolts or a 5/16” washer to ¼” bolts.
AC43 or similar approved data gives guidance on accepted means for carrying out typical aircraft
maintenance tasks
– such as safety-wiring etc.

Thread bound nuts can carry far less load and are much more susceptible to failure.
WARNING
DO NOT REUSE SELF-LOCKING NUTS
2.12 Aircraft Structure
In all Jabiru Aircraft, due to the monocoque construction the majority of the structure is primary. The
components of the aircraft which are secondary structure can be identified by the fact that they are
designed as fairings and are generally removable. Examples of secondary structure are the engine
cowls, speed fairings, ventral fin and wheel spats.
2.13 Engines
The engines used in Jabiru Aircraft are not discussed within this manual. For details of installation,
maintenance and overhaul refer to the engine manuals appropriate to the engine model.
Up-to-date engine manuals are available from the Jabiru Aircraft website; www.jabiru.net.au.
