Aircraft Corrosion Protection

There are many forms of corrosion and it is recommended that you pull out AC 43.13-1 and read over the section on corrosion and become familiar with what the different forms look like. There are some really good pictures and text on what causes corrosion and how to treat it.

An ounce of prevention is better than a pound of cure.

At this stage you have new parts and hardware and all is nice and shiny new. Depending on where you live, in the matter of only a couple of months you can begin to see signs of corrosion at different areas of your new gyroplane. This can be prevented and it is suggested the earlier you combat this corrosion the better. The battle of corrosion will be a never-ending one but if a proper corrosion control program is developed corrosion can be held to a manageable level.

Corrosion is usually caused from two dissimilar metals abutting each other and a form of electrolyte (usually water) that causes an electrical reaction that will eat away at one of the metals much quicker than the other. Modern protectants can amazingly penetrate very tight hardware and displace water moisture and coat the part with a protective film. Rain, snow, wind and washing can remove the protectant and it should be reapplied at regular intervals. The little can of magic juice can save you some serious time in treating corrosion and some very costly repairs.

We have some items that are not very aerodynamically shaped and are out in the elements all the time. These areas tend to be more prone to develop corrosion and even greater means of protection may be needed. First try a can of protectant and see how effective it is for your area.

There are many products out there and they all work in the same way. The size of the molecules is small enough to squeeze between very tight components and then has a weight that is very great that can push the moisture out of the joint. That was a laymans explanation but you should get the concept. The greatest differences in the products is durability- how long they last, affectivity- some do a better job than others, ease of application and ease of removal. The only products I would steer you away from is waxy type products. This stuff will trap dirt and can be difficult to completely remove from an area. The oily type products are easier to apply and remove and do not seem to trap as much debris as the waxy type.

There are also some products available that provide a moisture and air barrier. These products are painted on with a small brush and have the appearance and thickness of a tar -like substance. When dry these corrosion preventive compounds can be very durable and provide an effective barrier on exposed parts such as clevis threads.

Corrosion protection is just something you will have to do or else spend greater sums on buying replacement components. Be sure to find out what compound to keep these compounds away from as some of these products can deteriorate rubber compounds very quickly. Take a look at your ship and keep those parts in top shape.

Soon you will have to put the interior together- if any- so lets take a look at Upholstery.
