Did anyone offer an accurate assessment of the metal found ?
Whenever I talk to an engine shop , I ask for the assessment microscope , spectrogram .
Without an accurate metal assessment , type of metal quantity etc it is just guessing .
All engines make metal all the time , oil analysis monitoring will give an accurate assessment of when the quantity and type of metal require action.
Most commercial aircraft use oil analysis to predict the health of the engine and pull engines off line when required .
i have seen chunks of metal the size of your pinky after a chip light in one engine . They went back and read the analysis on that engine and changed a few gear boxes on other engines after that one engine seized on shut down .
