This feels more like engine manufacturer QC rather than anything Airbus.
Because also, from Wikipedia: On 22 June 2011, Qantas announced that it had agreed to a compensation of AUD$95 million (£62 million/US$100 million) from Rolls-Royce. - skipping Airbus entirely.
The whole business of airliners engines is fascinating in its own.
AIUI when you're buying a plane from Airbus, it's possible/frequent to own the _airframe_; but not the engines — the engines are often _leased_ (sometimes directly from RR/GE); I've even heard of cases where each engine will be owned by a different entity!
