If your post is a "summing up" in an effort to "move on", fair try.
I'll attempt to go the other way. It is a facet of aviation Press/Response that interest dies quickly, perhaps because of technical content. Perhaps other factors. Rolls seems bent on caching this event with other "Lone Defect" incidents, "Whirl Mode", "Skin fatigue", "IPT failure" (2003), etc.
Another look at the "Stub Pipe"?
"Misaligned Counter bore". Fine. What then induced the severe wear on this tube's end? Improper Connection? Incorrect Maintenance? Did the tube fail in service due to fatigue? Or was it Vibration induced by failing IP Shaft Splines?
The Emergency soft-ware "fix" is not a "fix". It is an accelerated warning to interrupt a chain of failure that Remains on the wing? Whereof Lufthansa? How did the Replace/Repair schedule seem to target Qantas for there Naivete? Out of sight out of mind "Engine Maintenance" ?
One dreads the continuation of outsourced Mx, and the loss of stable, and proven domestic care for Aircraft. No reflection on Lufthansa in this case, but Leasing one's Power might need another glance from people other than accountants?
what do you think?
