The ownership of an aircraft can be an expensive endeavor, especially when it comes to the aircraft’s propellers. While the maintenance of corrosion, fuel contamination, and exhaust problems is comparatively less costly, propeller issues can be quite heavy on your pocket. However, you can avoid costly repairs and potential replacement by performing regular inspections and preventative maintenance tasks. This can make your aircraft’s propellers last longer and increase its useful lifespan.
One of the most critical components of a well-built and well-maintained aircraft is its propellers. Therefore, aircraft technicians consider frequent preflight run-throughs or ‘walkarounds’ an essential part of the propeller inspection checklist. The last thing any aircraft owner or pilot wants is to be forced to make an emergency landing because of propeller failure. Continue reading to find out some useful steps you can take to increase the lifespan of your propeller.

Perform Regular Pre-Flight Inspections
Performing regular inspections of your aircraft’s propeller before each flight will allow you to detect any emerging problems before they turn into more significant issues. A thorough preflight inspection of your propeller will help you catch any physical damage that is visible to the naked eye. These may include nicks, chips, gouges, paint damage, and more.
First, you need to look for visible signs of external corrosion on the blades. Then, proceed to check for loose or missing hardware and cracks in the spinner and spinner assembly. Finally, check to see if there is any oil or grease leakage in the spinner’s interior.
A small amount of grease or oil spill is normal if you have new propellers or you are in a hot climate region, however, it should not be trailing down the blades.
Make Sure Your Propellers Are Clean
The propeller of an airplane is one of the components of your aircraft that receives the most stress, so after every flight operation, you should give it some well-deserved care and maintenance. You must make sure that you do not use a pressure washer when cleaning your aircraft’s propeller. High-speed jets of water can damage the internal components and remove paint from the surface.
Instead, use a soft cloth and a simple soap and water mixture to wash the propeller blades after each flight. It will ensure that all dust, dirt, and bugs are completely removed without scratching the surface. Always make sure that the blades are pointed in the “down” position before starting, then continue to wipe toward the ground. This will help prevent water from entering the hub.
Check The Balance Of The Propeller
Two types of balance checks for aircraft propellers are usually performed, which include static balance checks and dynamic balance checks. A static balance is typically performed for airplanes during overhaul services. This is done each time a propeller is removed from the aircraft.
On the other hand, dynamic balancing is a specialized service that is performed when the entire engine and propeller assembly is running. Dynamic balance checks allow you to measure the vibration magnitude of your aircraft’s propeller and engine. It enables the propeller technicians to identify areas for balance correction.
The dynamic balance correction process is important to reduce cabin vibration, resulting in a smoother and more comfortable flight. Although it involves an additional service charge, it is important to protect the health and longevity of your aircraft’s propeller as well as its airframe, engine, and avionics.
Take Care Of Your Surface Paint
The paint of your aircraft serves as an extra protective layer that can add significantly to the life of your propeller and overall aircraft. During each pre-flight inspection or walkthrough, always make sure to check for flaking or chipping in your paint. In case of minor damages, you can do some paint touch-ups on your own easily.
For more major paint damage such as surface corrosion, it is best to have the repainting of your propeller blades done by a professional. Only an expert with the right skills will be able to perform a repainting job as authentic and useful as the initial paint of your propeller or aircraft.
