Chaps, you're all so touchy! Any perceived insult to an engineer is jumped on, but it's OK for engineers to make insulting references to pilots? OK, we'll let it pass!
Engineers won't decide if it is repaired. they will report- the decision will come from MAD-'get your wheel jacks and crosshead screwdrivers out and get on with it!', or:' paint Iberia out on the fin and get the chainsaws out quick!'
As for repairability, look how Qantas mullahed this 747 at BKK (now happily flying paying guests around):

It will be interesting to see what problems modern plastic aeroplanes experience, however exactly how revolutionary is the 340-600? It still has a standard duralamin fuselage doesn't it? I still get the impression the 747 is worse than this 340 in that the 340 only has superficial damage.
