Does RR sub out it's manufacturing of parts or do they machine everything in-house?
The final machining is done in house, but the disks come in a circular piece originally, although the NDT (non destructive testing) is contracted out to another company based in Derby.
It will be interesting on what action is taken against manufacturers of the disk metal/NDT testing contractors if it turns out to be a material flaw.
