Serious Dangers of a Cracked Muffler

One of the last things you want to experience is having a cracked muffler during flight. Though it may not seem much, the muffler does more than reducing the plane engine’s noise. In reality, the muffler has a critical job of preventing the carbon monoxide from the exhaust from entering the plane’s cabin. But how does carbon monoxide affect the people on board the flight? Let’s find out.

Carbon Monoxide Poisoning

Carbon monoxide is a gas produced from burning fuel. This gas is odorless and colorless, making it hard for people even to know they are inhaling it until it’s too late. Carbon monoxide has several effects on the human body, including headache, dizziness, and nausea. In higher doses, it can lead to loss of consciousness or even death.

Knowing these, you may now have a clue on why carbon monoxide is hazardous for the pilot and the passengers. Carbon monoxide poisoning, even a mild one, may result in the pilot having impaired judgment and disorientation. It can be fatal for everyone aboard the plane since the pilot may lose control over the aircraft, and they may all plummet to the ground. There have been many cases of crashes related to carbon monoxide poisoning, and they are no hoax.


How to deal with Carbon Monoxide Poisoning

If you are on the air and suspect that you are affected by carbon monoxide poisoning, follow these steps to increase your survival chances.

  •   Turn off cabin heat– This prevents more toxic gas from entering the cabin, but it does not remove what is already inside.
  •   Take in the fresh air– Open your air vents and windows (if possible) and let the fresh air flow inside.
  •   Make an emergency landing– Land your aircraft as soon as possible, but make sure it is a safe landing zone. Time is very crucial.
  •   Seek medical help– Even though you have landed safely, you still need to get rid of the toxic substance in your body.


Importance of Repairing a Cracked Muffler

A healthy muffler allows the plane to release the exhaust gasses from the engine efficiently. It also reduces noise and prevents cold air from flowing inside the engine. Cracked muffler and exhaust pipes can allow carbon monoxide to seep inside the cabin, endangering everyone on the plane. To prevent this, one must conduct regular maintenance on the plane, ensuring that it can run on its top form.


How to Prevent Mufflers from Cracking

These are the steps you need to take to prevent the muffler from breaking and the deadly gas from getting inside the cabin.

  • Separate the muffler from the heat shroud.
  • Inspect the muffler itself thoroughly, noting all major or minor changes in appearance.
  • Make sure that there are no parts that are about to break and cracks that might occur later.


Inspecting aircraft mufflers require a certain amount of skill and knowledge. If you are not confident to do it yourself, contact professional aircraft maintenance. It will prove useful in the long run.
