While some people may not pay very much attention to their plane's exhaust system, in reality, it is an extremely important component of your plane. We’ve compiled a list showcasing the things that you should be familiar with regarding your plane’s exhaust system. This information can potentially save you from spending tons of money on repairs.
What is the exhaust made of?
When it comes to the exhaust system, there are mostly two materials that are used; stainless steel and Inconel. Both of these materials can be difficult to tell apart for new mechanics. They look and feel similar which causes many people to be confused between them. More experienced mechanics will be able to differentiate between them by performing stress tests or chemical tests.
While it is difficult to differentiate between them, you should know what material is used in your exhaust system. This is because both of these materials require different maintenance techniques. This does not only apply to the mufflers, however, but the plane owner should also know every material used in their plane so that they can properly maintain it.
Before you start the inspection, you should remove all of the additional components such as the shields from the mufflers or the stacks so that you can thoroughly inspect the exhaust. If you do not properly disassemble the muffler, you might miss some cracks or leaks in the system which can lead to bigger problems.
You will have to spend more money to get the exhaust system repaired if you do not properly conduct a regular inspection of the system. You can also conduct pressure tests which will help you in finding leaks more easily.
Alongside leaks, you should also look out for any corrosion, cracks, or distortions. To make this process simpler, you should hire a professional mechanic and have them review the exhaust system. They will be able to clearly see where problems may exist and fix them immediately. Finally, you should make sure that all of the nuts and bolts are properly tightened so that they do not cause any problems while flying. Be sure to properly tighten all components, otherwise, it can be really dangerous.
Take your time when checking the muffler
For starters, the muffler of a plane can seem like a really complex component. This can be overwhelming for many people, which is why they do not take their time to properly check each and every area. You should conduct heat stress tests regularly so that there are no issues when temperatures get high.
Also, it is suggested that you do not use the same gasket more than once. Which is why you should make sure to replace gaskets after every inspection and tear down. Also, make sure that you replace or repair any damaged components on sight instead of waiting for them to stop working. This will be beneficial in the long run as it will save you repair costs and save you time.
Finally, make sure that you find the correct sized components for your exhaust system. Do not forcefully fit anything in the exhaust as that can be fatal to your flight. Also, beware of any potential backfires as that can take a huge toll on the engine. Make sure that the exhaust system is clean and fully functional before you take off for each flight.
