The PA-28s at the FBO where I spend most of my instructing time routinely
got 2500 hours out of 2000 hour engines. When mechanics see an engine every
100 hours (which ours did), they are aware of service limits.

Flight school use actually is quite good for exceeding TBO

That's my understanding, but a student of mine, an A&P, insists that
every flight school that he's worked has overhauled engines at TBO,
and he's had others confirm that with their flight operations.

I can't imagine that any flight operation would incur the added
expense if this were clearly unnecessary.
