According to Airbus, A380 wing cracks (“non-critical wing rib-skin attachments on a limited number of A380 aircraft”) are a non-issue because they “do not make the planes unsafe.”
The plan is to use scheduled 4-year maintenance checks called “D-Checks” to screen planes for signs of cracking.
We are just curious if this was a manufacturing error or a design flaw. And even if it is not a safety issue, the idea of just waiting around till a scheduled check seems chancy at best.

Austrian Airlines flight OS-836 had to divert and make an emergency landing in Bucharest, Romania, on May 8th.
