Had a nice chat with him at the OSH. Learned a bunch


LOP ops, proper oils and why, flying way, way past TBO. On the TBO topic, now they have a great stats on the catastrophic engine failures and suprisingly they are majority in 0-300 hours. Once you are passed TBO, actually engine gives you plenty of warning before the real issue comes. With proper care, operation and oils, there is no need to rush into the overhaul.

To add to previous, these are some of the notes that I picked up:


TBO is just a suggestion and not the law.


Things that affect the life of Lyc. and TCM engines are:


1. Corrosion from non use
Take a look at the cylinder heads, push rods


2. High CHT
400F for TCM
420F for Lyc.


3. Cold starts cold ambient temps
    Dry starts from non use even in warm ambient temps


4. Running the engine if not flying
If you have to reposition the plane on the field get it towed or fly for an hour and taxi it in.


5. While using 100LL use cam guard.


6. Engine oil: use multigrade 4-6 cold months and single grade in warm months
This will depend on where you live of course.


7. Don't use 15w-50 in Cirrus and Cessna Corvalis. (I don't fly these so did not ask why, but it has to do with their high perf and tight cowling i guess)


8. Invest in the multi probe engine monitor from the reputable supplier and shop.


9. Monitor your engine oil analysis, especially if there is a lot of dirt or debris on the airfields you fly. You must have less than 10ppm silica in the oil analysis report.


Hope that helps and feel free to comment and add to it.

All of Mike's webinars can be found in the EAA video archives: http://www.eaavideo.org/channel.aspx?ch=ch_webinars

A lot of great advice there.  Aircraft owners
should know that they can contact Mike and
he can help them diagnose problems, and
make big maintenance decisions.

Since I bought my airplane I've been studying Mike Busch's writing and webinars the way some people study religion.

Mike has forgotten more about airplanes
than TC will ever know.
