DYNAMIC PROPELLER BALANCING
Staff at North West Aviation Pty Ltd are
fully conversant with the use of ACES Probalancer which was
designed and built for rapid, accurate dynamic balancing of

Commonly asked questions relating to propeller
- What are the benefits of dynamic propeller balancing?
Dynamic propeller balancing increases component service
life and ride quality of both crew and passengers. It
minimises vibration levels in the rotating components
to a level that will ensure the longevity of the components
and a longer service life of the propeller. But, increased
component life is not limited to just the rotating components.
Firewalls, instrumentation and even aircraft structural
members reap the benefits of low vibration levels.
- Why should I have my propeller dynamically balanced?
Your aircraft has a brand new propeller fitted on a fresh,
just overhauled engine and the propeller was statically
balanced so why bother balancing it again? You wouldn't
think of buying a new set of tyres for you car and then
not have them balanced would you? Think about that the
next time you spend thousands of dollars on an overhauled
engine and/or propeller.
- Aren't engine and propeller components manufactured
Yes. But balancing is only done on individual components.
When components are assembled, new imbalances may be created.
All components of an engine assembly from the crank all
the way out to the spinner are manufactured to strict
tolerances, but until the power train and rotating components
are balanced dynamically, as an assembly, the job is only
- How long will a dynamically balanced propeller stay
Dynamic propeller balancing should be performed every
400-600 hours under normal use. But it should also be
performed after propeller or engine overhaul or if significant
repairs are made to the propeller.
