RR's main problem now is engine production to make up for the lack of spares. As to
PR, I am not sure what they could add to the information already given. We already know that the full accident report will take about a year to produce. They will not waste time reponding to unfounded rumours.
I am interested to know how Airbus are going to fix the damaged aircraft. I suppose they might be able to patch it up sufficiently to fly it back to the factory. Does anyone know the plan?
