Jet engines today are also routinely torn down, inspected, and rebuilt if necessary - much more often than piston engines are, I gather. But that's because of the overall materials stress and the necessary safety factors involved, not because of any general mechanical complexity. I mean, I guess you can count having all of those individual blades as being "complex", but in reality these are just the parts that make up mechanically simple fans and compressors and such.
