North West Aviation

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 aircraft propellers.

We have dynamically balanced a large range of propellers installed on single and twin engine, fixed wing aircraft.

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 to tolerances?
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 half done.
How long will a dynamically balanced propeller stay in balance?
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.
