OWNER MAINTENANCE
2.9.1 FACTORY-BUILT MODELS
All Jabiru Aircraft, including factory-built models, have been specifically designed as simple aircraft
which can be maintained by owners to a large degree. Jabiru Aircraft allows normal maintenance up
to 100-hourly servicing to be carried out by the owner
wherever this is allowed by the aircraft’s
operating category. This servicing includes:
-
Oil & oil filter changes
-
Fuel filter changes
-
Brake pad changes
-
Tyre changes
-
Spark plug changes
-
Normal engine maintenance between 100-hourly maintenance. Refer to Engine Maintenance
Manual for details.
Every 100 hours or Annually (whichever happens first) a 100-hour inspection must be carried out by
an Authorised Person (such as a LAME. Refer to the RAAus Operations Manual for RAAus aircraft
Australia).
CAUTION
It is the operator’s responsibility to ensure that the factory-built aircraft is correctly maintained
for the intended use.
2.9.2 KIT-BUILT MODELS
Many models discussed in this manual can be registered under a variety of different categories
worldwide, at a variety of different weights and operating requirements. The owner must consult their
local airworthiness authority to determine what level of owner maintenance is allowed. As an
example, in Australia aircraft registered in the “Experimental” category may be maintained
exclusively by the owner/builder, or by authorised aircraft maintainers.
CAUTION
It is the operator’s responsibility to ensure that the kit-built aircraft is correctly maintained for the
intended use.
2.10 AIRCRAFT SPECIFICATIONS
Leading particulars of the aircraft discussed in this manual are given in Section 2.16. If these
dimensions are used for constructing a hangar or computing clearances, remember that such factors
as tyre pressure, tyre size and load distribution may result in some dimensions that may be
somewhat different from those listed.
2.11 CENTRE OF GRAVITY LIMITATIONS
All JABIRU models are relatively light weight. The installation of equipment may significantly alter the
approved CG limits of the aircraft. Therefore, all proposed fixed installations must be approved by
JABIRU AIRCRAFT Pty Ltd or a
person authorized to revise an aircraft’s weight and balance
information (such as the holder of a CASA Weight Control Authority)
2.12 TORQUE VALUES (IN FIBREGLASS)
Unless noted otherwise, all bolt torque settings detailed within this manual are for clean, dry threads.
When checking fastener torque, use the following procedure:
-
Ensure the fastener to be checked is clean and dry before proceeding.
-
Where a reversible wrench is being used, set the torque to a value slightly below the target
torque and LOOSEN the fastener slightly (approx 1/3 or a turn). The wrench should “click” –
indicating that the fastener had maintained its set torque. If the fastener torque has reduced
significantly it may be an indication of damage or degradation to the assembly and should be
investigated.
