The JAR regualations are similar, except that I believe that the report has to reach the CAA within three days. I can assure you that the UK CAA will go through the paperwork in minute detail. As all of the company communications were by ACARS, these will also be available in hard copy, so any commercial pressure will be evident. The crew will also be interviewed by the company and the CAA. I'm sure that the eventual report will be factual, unbiased and just, unlike some of the comments here on PPRuNe.
