Aussies have been trying to ground the entire P&W PT6-A fleet for years. They tend to over-react a bit, IMO.
That thing is the Titanic of the skies.
How do you feel about the 787?Pretty much been my opinion of it from the beginning.

Hmm... Diamonds are pretty much all CF structures, aren't they?
sailplanes started using carbon fibers for spars at least back in the early 80's...

The A380 is conventional construction, not composite.
Then I don't understand, are the ribs glued in?
Airbus says it has already developed a fix to wing cracking found on some Airbus A380s.
The cracks, first reported by the Sydney Morning Herald, have been seen by at least Qantas and Singapore Airlines. The cracks were first found on the Qantas A380 that suffered an uncontained engine failure with one of its four Trent 900 engines two years ago.
Airbus confirms the cracking on “some non-critical wing rib-skin attachments on a limited number of A380 aircraft.” The aircraft maker adds that safe operations of the fleet are not affected and no flight limitations are being put on the A380.
Airbus says a inspection and repair process has been identified, although it would not detail how the fix is made. The repair is being done as part of four-year maintenance checks, it adds.
The approach has been validated by the European Aviation Safety Agency, Airbus says.
IIRC, I saw a video showing spin welding, but that may only have been the skin/skin edge bonding. They showed a machine that looked something like a router bit to my admittedly uneducated eyes.Then I don't understand, are the ribs glued in?
