The International Cessna 170 Association

While I'm no metallurgist, that's a clean break. That is not a crack that propagated from a small flaw. That type of failure usually happens with a single incident, not a fatigue type failure over time.

the plane is so stable, even with the winds today it was pretty straight forward.

...

Plans include flying it and flying it some more! Then maybe I'll look at mods.

Was online looking for info and stumbled upon this site.

I've been reading and reading - some really good topics and lots of great knowledge on here. I've got tons of questions, but I'll try to put them in the appropriate threads.

Thanks in advance for answering my dumb questions!
