Repetitive inspections of spare engines? Let me get this straight, you inspect what is a brand new engine and after a period of time you have to reinspect it because it may have developed a serious structural fault sitting in an engine stand? I wonder how GE is going to make this up to their customers.
Nothing new in how they will probably handle it like any other engine within a warranty period. Typically such warraties are very genereous as specified in a contract with their new product customers.
In other words business as usual (on the business side).
I believe that RR went through something similar a couple of years back as did P&W.
