Has the AAIA notified CX that an ICAO Annex 13 investigation is officially underway in accordance with CAP448B?
Until CX are notified accordance with the AAIA SOP manual, the CAD led and ex CX staffed Investigation Authority are just collecting information.
As there are no CX investigation reports published on the website, ipso facto, there have been no investigations of CX.
Worth following up as the CAD are that devious.
