It may be best, at his point, to remove all restrictions, due to lack of evidence, and let industry decide if they want to operate the 225.
Lack of evidence does not mean something didn't happen.
Let's not forget the investigation is still in its early stages with a search for significant items still ongoing. It's easy for us to sit at our computers hypothesising but the investigation can only publish factual information and their analysis of those facts. I assume that if there were facts relating to the airworthiness of the 225/332 the AIBN , Norwegian CAA,UK CAA and EASA would issue something.
However frustrating it is, we have no option but to wait for the investigation to turn up something to either eliminate potential causes or focus the investigation on a particular issue. I've no doubt that there is significant pressure on the investigation team to find the cause or causes of this tragic event.
