22.9 PROPELLER BALANCING PROCEDURE
Propeller balance should be checked by locating a 16mm tube to firmly fit the centre mounting
hole of the Propeller and balancing on "knife edges".
Tolerances:
-
Imbalance shall not exceed the following limit whatever the position of the Propeller in the
plane of rotation: 750 mm-gms (approximately 1 gm at the tip).
The balance may only be corrected by the application of epoxy paint. Any other method of
securing balance is PROHIBITED.
Propellers outside these limits should be rejected as unserviceable or returned to JABIRU for
assessment and possible repair.
