In this manual we have used a “spanner scale” to help technicians approach a job. Anyone
considering undertaking a task in this manual must realistically assess themselves against this scale
and not attempt any task for which they lack knowledge or the required tools.
The Spanner Scale
Translation
Simple, basic, straightforward. A careful layman, with guidance, can
achieve this.
Straightforward, but with some technical bits. Basic knowledge, care
and guidance needed.
Straightforward, but requires special tools, training and/or judgement.
Sound basic knowledge guidance and a careful approach are required.
A technical job. Take your time, double-check everything. Only for the
experienced maintainer.
A difficult job. Requires special tools, solid skills, good judgement.
Only for experts.

CALIBRATIONS
While all Jabiru Aircraft are designed to be as simple to maintain as possible some professional tools
are required:
-
An accurate, calibrated torque wrench is required. The wrench must have a suitable scale for
use on the fasteners typically found on Jabiru Aircraft
– for example a wrench with a scale from
20
– 100 lb.ft is unsuitable.
-
An accurate tyre pressure gauge is required.
-
Accurate scales and spirit level if the aircraft is to be weighed.
-
Other tools as required to maintain the engine and propeller
– refer to the applicable manuals for
these products.
Specialist tools such as the torque wrench and scales are required to be calibrated regularly
– a
minimum of once a year or more often if they are being used frequently.
In addition, CASA requires that calibrations be carried out in a way which is traceable to a NATA
laboratory.

USE-BY DATES & STORAGE
Some products called for by this manual
– including thread locking compound, resins and glues –
have a use-by date. Care must be taken to ensure all such compounds are within their shelf life
before applying them to an aircraft.
Loctite products typically do not have their use-by date marked on the bottle. For these products it is
necessary to note the batch number on the bottle and contact the distributor for shelf-life information.
Similarly, for many products the shelf-life assumes a certain type of storage
– i.e. sealed,
temperature controlled etc. Maintainers must ensure that such products are stored appropriately.

GENERAL DESCRIPTION
The JABIRU aircraft described in this manual are 2-seat, high-wing monoplane composite aircraft of
monocoque construction. They are equipped with fixed tricycle landing gear of composite
construction. The steerable nose gear is a welded metal, trailing link assembly with rubber springs.
The aircraft are equipped with a JABIRU, 4 cylinder, 4 stroke engine of around 80hp or a JABIRU 6-
cylinder, 4-stroke engine of around 120hp. Both engines are optimised to drive a 2-bladed, wooden,
fixed pitch propeller.
