Airbus hit by new A320 quality issue days after massive recall

Airbus said it was inspecting "a limited number" of A320s after it identified a quality issue with metal panels used on the exterior of the plane.  It says it's unlikely to cause any safety issue and all newly produced panels conform to requirements.  The revelation sent the planemaker's stock tumbling, coming days after a software recall resulted in the grounding of some 6,000 passenger jets worldwide. Also in the segment, cryptocurrencies continue to slide after a very bad November.
