From C|Net:

The BBC reports that the engineers are concerned about small cracks that have appeared on the wing ribs of some Airbus A380 airplanes, and that they’re calling for the whole fleet to be grounded for investigation.

Airbus:

We confirm that minor cracks were found on some noncritical wing rib-skin attachments on a limited number of A380 aircraft. We have traced the origin. Airbus has developed an inspection and repair procedure, which will be done during regular, routine scheduled four-year maintenance checks. In the meantime, Airbus emphasizes that the safe operation of the A380 fleet is not affected.

I don’t like the words “aircraft”, “wing” “cracks” and “noncritical” to share the same sentance. Doesn’t sit well.

I’ll stick to trains.
