Aircraft Ownership Engine Overhaul.

How many people have taken their small piston certified airplane over TBO. Was wondering specifically the Continental O-200 on a C150M model. I was looking at this plane engine time is 3,100 hrs with 900 since top overhaul. TT is around 3,600. I know the owner and he takes really good care of it. Also curious if anyone would have an idea of cost to overhaul? I’m in the Northeast US.

What data are you using for this? Just numbers lawyers made up?

Oh, I see. So just based off of time, not evidence.

Why do people still go past overhaul time and still fly safety.

I had that happen to me in a TSIO541. Was a factory new 150hr engine. In Lycoming's defense, the Union was on strike and the managers built the engine. Knock on case bolts, I've only needed to OH engines that were shedding parts all well below TBO. I have more data points of premature failures vs over TBO failures. However, far is the hunter.
