aircraft engine testing
ULC guidelines for any planned oil change in a piston engine
In accordance with Guideline No. 9 of the President of the Civil Aviation Authority dated 29.08.2016, the scope of testing aircraft with piston engines includes spectrographic analysis of oil (testing of the content of elements in oil), which makes it possible to determine the trends of changes in engine wear.
Regular analysis makes it possible to determine the normal characteristics of engine wear, and thus quickly catch abnormal increases in the content of individual elements. In correlation with the knowledge of the metallurgy of individual engine components, it is possible to easily relate an increase in the content of a particular element to a particular component, and thus avoid serious engine failure.
