I believe we soon will get more information from AIBN and Airbus based on fact. FDR/CVR and most of the essential parts are recovered while search continue. Airbus may have their theories based on findings so far. Probably they can not publish theories until AIBN agree. Internal MGB malfunction would be very serious for the future of the EC 225 in the North Sea and worldwide. Suspension bar / fitting issue will be more easy to correct within a short time frame.
