That's a great question. I do not know for certain, but I suspect the answer lies in reliability and much longer intervals between servicing and overhauls.
Piston aircraft engines have a recommended time between overhaul of 1200-2000 hours (with outliers above and below).
Jet aircraft engines have a recommended time between overhaul of several times that, with required inspections typically at slightly longer intervals than piston engine overhauls. (In a fixed install turbine plant, you might be able to skip the inspections as well, and just use trend monitoring data to determine when to take the turbine out of service for maintenance/overhaul. In an aircraft carrying people, the risk profile is a little different.)
