There are some rigid and strict procedures in place to maintain aircraft propellers, and rightly so. The optimum condition of any aircraft propeller is essential for onboard safety. Propeller inspection is the most important part of this, as it involves taking measures to prevent damage and issues.
Corrosion is one of the most important factors adding to the deterioration of an aircraft's propeller. Corrosion can cause expensive and dangerous damage. However, small preventing activities can save you from all these unwanted damages and repair expenses, all it involves is you being informed and educated.
This blog post explains some simple and easy propeller maintenance procedures.
What Is Corrosion?
In simple words, corrosion is the breakdown of material - generally metals - due to a chemical reaction. Usually, it involves the oxidation of metals, when they come in contact with oxygen in the air or water molecules.
Corrosion can also occur when an aircraft's materials come in contact with acidic or basic materials. Corrosion impacts the physical properties of the material, making it less effective and weak. When it comes to an aircraft this can be extra damaging.
Prevent Corrosion With Aircraft Propeller Maintenance Procedures
Corrosion can be catastrophic to your aircraft. Propellers are the heart of an aircraft and any failure in this part can lead to mishaps in the air. Fortunately, there are easy yet significant maintenance procedures that you can follow to avoid propeller corrosion and other flaws.
Wash Your Aircraft
Taking a little time to wash your craft can pay you significantly in the long run. Make sure to rinse your aircraft after a long flight to remove corrosion-inducing agents.
It is worth taking some extra time to wash its propellers. Make sure not to use a pressure washer and apply corrosion inhibitor products wherever needed.
Cleaning your propeller blades can increase their lifespan and reduce the chances of corrosion. However, keep in mind propellers of different materials will have different washing requirements. Some are as follows;
- Aluminum and steel propellers should not be washed with caustic and acidic materials. Also, don’t use steel brushes, power brothers, or steel wool. Instead, use a simple brush and cloth with a suitable cleaning brush and apply the polish wherever needed. Once the propeller is cleaned, coat it with engine oil.
- Wooden propellers are best cleaned using warm water with mild soap and with the help of a cloth or brush.
Use Covers
Covering your aircraft can help protect it from damaging materials and elements, this can also be applied to the propellers. Investing in quality propeller covers can increase the lifespan of your propellers and keep them safe from corrosion - as covers cut the contact time with corrosive agents, oxygen and moisture.
Keep The Aircraft As Dry As Possible
Keeping your aircraft dry is easier said than done. This is especially true when you live in a damp climate, but it is essential to try and keep the craft dry. Therefore, make sure your aircraft is dried completely, and never let your propellers drip dry.
Carry Out Regular Inspections
Ultimately, implementing a strict inspection and maintenance schedule for your aircraft is the best way to prevent its corrosion. A scheduled propeller inspection will inform you about any changes, flagging up any inconsistencies immediately.
What Is Involved In Propeller Inspection?
A regular inspection should include assessing the propeller physically and other features. As a rule, you should include the following in your inspection;
- Braze and weld sections for any signs of weakness and failure.
- Look for any scratches, nicks, or flaws on the propeller.
- Ensure oil levels and lubricant requirements are sufficient.
- Check bolts and screws for tightness and safety.
- Check Propeller blades and spinners for any excess oil or grease presence.
