Maintaining Austro beyond 1800 TBR

[Farra]

There is a very long and detailed article on Savvy's data collection and analysis of legacy engine data in the March issue of COPA Pilot.

I'm not sure if any of this is applicable to Austro engines though?

If you intend to eventually fly your Austro engine(s) past TBR, I strongly suggest sending oil samples to Blackstone after every oil change -- they have considerable experience with Austro (as well as automotive/truck diesel) engines, and provide very detailed reports with great explanations of what they're seeing in each sample. They (and you) will then easily be able to monitor trends as you put more hours on the engine(s).

Thank you. I will definitely look into this.

It's applicable if you want to understand the depth of the data and analysis that went into the "fly it beyond TBO" recommendation for legacy engines.
