Howdy there. Big G. I think I'll have to take responsibility for the comment about the Fire being of insufficient length and ferocity to "Melt" the DA. I also have opined on the surge as the cause (one of) the IPT disc's erratic spin, a contributory factor in its loss, and I thank you for the support. I have held from the beginning that mechanical slip and effaced wheels causing great friction heat did in the Drive Arm, the Stator, and of course ultimately the IPWheel. Ingenious Helical Splineage?? Oh yeah, but remember, what screws in, also screws out. The bearings were not mentioned in the AD because technically they ARE 'Static Turbine Components', and were therefore covered in Rolls' expression of potential catastrophic failure. Not really non disclosure, 'not really'.
My conclusion had everything to do with the AD, a document that was rather suddenly abandoned in favor of a "may have intiated events that caused...." reported by RR through the ATSB.
Pray, what can be said about Vibration, the mother of this blast??
