It is possible for parts of an AAIB report to be used as evidence in a criminal trial if the content is deemed admissible and the required parts are presented formally as a witness statement. In AH's trial, one example was that 'Annex H - Report on Data Gathering Flying Related to the Accident to G-BXFI' from the AAIB report was presented by the author and thereafter was available to the court. At this point, the author, who had been working for AAIB as an advisor, became an expert witness for the trial.
