So why wouldn't they, repair some wire bundles, repair some damaged components, bolt on a few new engines, put in some temporary structural repairs in the wing and ferry the thing back to Airbus for full repair?
It isn't like it the airframe is broken in little pieces or burnt up.
The factory in Toulouse is set up to manfacture aircraft not repair them!
When your car is in a accident you don't take back to the factory for repair!
Airbus, like the other OEM's and MRO's have field teams that can handle the repair with parts supplied by the factory.
