Thanks Old Engineer for your answer and also to PBL and lomapaseo,
Well I hope we'll get more info about how partially was the wing structure affected (i.e. how reduced was its resistance to loads)
Would you guys think a general guide in the QRH, as you OE suggested, could tell the pilots about the probability of how bad the wing should be affected, depending on what the pilot sees (wing + engine) (I know it won't be precise) ?
This would give pilots some more situation awareness before taking the decision to stay airborne to handle problems or decide it might be wiser to start an approach for an (emergency) landing
cheers
