Service Bulletins - Their Importance

Just a reminder to why we have service bulletins. It is super important to realize that the people testing and flying experimental engines (there are not many of us) at a certain point in time will find things that need to be upgraded and or changed.
We are always going to offer the best available, but it is important to pay attention to safety there is something to be said about those that fly behind their own engines and put service bulletins out, please remember to always be cautious of those that have claims of high hours with limited service bulletins….. odds are there is limited experience.
