Cessna 421C - GTSIO-520N


We have a Cessna 421C fitted with GTSIO-520N. Recently we did the SOAP Analysis Test of the Oil for both the Left Engine and the Right Engine.
Attach are the reports. Would appreciate if I can get input on the Internal Health of the Left Engine compared with the Right Engine.

You might get some information from Blackstone's website, there is a link to a sample report that may show averages,
Sample "explanation" report here, (link on the left that says Aircraft Explanation) notice the far right column of the sample report is "Universal Averages."

However, it's my (limited) understanding that a single analysis doesn't really tell much, way more useful when used as a trend monitor.
Hope this helps.

I know from my days as a hangar rat many decades ago, that S.O.A.P. is indeed a trend monitoring tool, however there were a couple of contaminants that required "further investigation" if high levels were shown, even at initial readings...hope all is ok with your GTSIOs, they are a lovely machine when treated properly..
