Special Maintenance
– Non-Approved Propellers
As noted, operators who choose to fit a non-approved propeller to their Jabiru engine do so at
their own risk and a system of additional maintenance is recommended to monitor the engine
for possible detrimental effects.
This section has been added to the manual to help guide such maintenance. However, as
Jabiru cannot anticipate every combination of engine, airframe and propeller this is strictly of an
informational basis. It is not a complete or inclusive maintenance schedule, rather an overall
guide directing which areas are likely to need additional attention.
WARNING
Using a non-approved propeller may lead to unforeseen operational, airworthiness, safety,
financial or legal problems. Jabiru Aircraft accept no responsibility for such issues.
The following are recommended IN ADDITION to the normal engine maintenance program.
Where the maintenance requirements listed below differ from those of a third-party propeller
supplier the lesser time interval should be used. i.e. if the table below calls for the propeller to
be re-balanced annually but the propeller manufacturer recommends balancing every 100
hours or 6 months then the propeller manufacturer’s recommendations should be used.
Visual inspections of the propeller and propeller flange installation should check for excess
metal oxide (appears as rust) or black chaffing dust originating from the flange. This is often an
early indication of movement between the parts and potential failure. Oil leaks etc in this area
and around the flywheel must be addressed quickly as they can both cause and mask other
problems.
Oil leaks from the front crankshaft seal have also been found to be an indicator of
unacceptable propeller vibrations in some cases.
