The 172S model is a 1999-2001 model year if I'm not mistaken. 6 years (less
how long it has been since SMOH) is way below any reasonable manufacturer's
recommendations.

If a plane (C172S) has 1600 TT but is at 250 hrs SMOH on an original
engine that's spec'd for 2000hrs TBO, does this mean that the engine went
in for overhaul prematurely? For what possible reason and how would I
find out?


Remember that TBO is based on hours run as well as calendar time. How
long was the engine in the airplane, and what does it's manufacture
recommend for calendar time to overhaul?
