I'm curious as to the overhaul policies at flight schools or rental
outfits. Do they typically do an overhaul at TBO? Our school
supposedly had one that had 5,000 hours, though it had been topped.
Not sure if this was the one that crashed.

Flight school use actually is quite good for exceeding TBO. Regular
use and frequent oil changes and hundred hours over very little calendar
time means your average 172 engine can still be going strong at close
to 3000 hours.
