Important Preventative Measures
Given the critical role of cylinders in your aircraft engine performance, a cylinder inspection is one of the most important kinds of preventative maintenance you can have done. In short, it helps you to get ahead of failure.
I have become outspoken and well known in the industry for my expertise on this topic. After working on countless cylinder inspections over the years, I realized that the Aircraft Owners and Pilots Association poster on cylinder inspections only shows late stage exhaust valve failure and does not differentiate between failure modes. In my experience, there are two failure modes. The most common is rotator failure. The other is failure due to operation beyond redline CHT. The rotator failure takes place over time and is detected by monitoring changes to the heat signature on the valve. Frequent inspections allow us to stay ahead of valve failures and prolong cylinder life.
