If you are interested in turbine engines, I highly recommend this guy's youtube channel as he will teach you everything you ever wanted to know and more about how turbines work. This video is about the compressor and it's actually a very simple component. Pretty much the only thing that can go wrong is that metal fatigue starts to form where the fan blades meet the hub. I suspect that the size of the compressor is resulting in larger centrifugal forces causing fatigue to occur quicker.
