(Engine/Fuselage 247h) tells you that it well passed the most dangerous first 100h, the engine was not undergoing OH yet and was not separated from frame. If you have a Cirrus with 15.000h lifetime frame, or even a 172 Cessna with 30.000h lifetime, it does not really matter, or? You could pennypick on hobbs hours, flight hours, block time, running time (became relevant since these nasty new TBR instead of TBO engines came into play) or whatsoever - it is always only an estimate for wear.
