Airbus forbids aerobatic manoeuvres in their RFM
That doesn't mean to say it cannot do aerobatic manoeuvres. It just means that it is not certified to do them. When prototypes and early production machines are demonstrated by company test pilots they do a lot more then the one in this thread did to demonstrate what they are capable of if only to show how big a safety margin there is for normal operations.
As has been mentioned earlier in this thread they have a more rigorous inspection programme but all pre-production machines have this anyway.
If something was possibly going to break they would fix it. Should one break without obvious damage like blade strikes or similar without any witnesses they could have a lot of explaining to do.
