Cracks found in A380 wing ribs

[Lyman]

Retired Peener,

I remember a vid of the upper skin in its machining stage, it was air tabled and routed to thickness. For its profile dimension, the lack of a platten or solid table made it look iffy to get good tolerance over the entire (single!) sheet.

So when the TRENT holed it, I immediately thought, well, there goes the monolithic integrity, they'll patch it. Did they? or did they ship a single sheet of upper skin to Aus, and layer it on site?

Can I assume a rough similarity between shot peening the lower skins to what a Jag scholar or Ferrari assembler would use an English Wheel? (beneficial residual stresses?)
