SLF here - since GA can occur for all sorts of reasons , is it not normal or even required to describe the cause of the GA? As mentioned it could be something outside the crew's control such as weather....in this case it was a mis-alignment resulting in near-miss.
So GA could be fairly benign vs not so.
Is there no reqmt to describe the cause? The docket seems to say AC took this very seriously indeed once they got the details.
