The only reason anyone even found out about the design change was because one of them blew itself to pieces while in commercial service.
Am I missing anything?
If RR had come out and said there was a problem when they found it, it is quite likely they wouldn’t be getting as much of the blame.
This may be inane but I suspect most design errors are discovered from actual commercial flying over a period of time.
I watch a lot of air crash investigation (when Mrs. LF) is not at home and although this is certainly a small selection of of incidents it predominantly identies flaws that are discovered long after a particular new aircraft or version comes into service. The 737 is a good example.
