Just a quibble, but the Airbus technical advisors do represent the state of manufacture and as such their findings are expected to flow through the Investigator In Charge.
It is likely that any outside influences in what the press prints come only from within states (Prime ministers, presidents etc.) and not from technical advisors on-site.
Be sure, if the Airbus advisors believe that their findings are different from what is stated in the report. Airbus will publish does findings in a "proper way".
