QUOTE: ''Very much doubt its a disc failure, far more likely a related spline or bearing problem which caused the disc to exit. Ive seen the paper from RR advising of this potential problem. The whole disc cannot possibly exit without a shaft related problem..''
Whirlybird1, your assumption is more or less correct and maybe one needs to ask the question as to what caused this possible combined shaft/bearing failure, internal oil firing maybe? certainly not defective materials. The similarities between this and a recent T1000 failure are worryingly familiar, more I can't say.
