EAP - I think that it is potentially possible to buy a A400 for civil use only, however I imagine it wouldn't be allowed by OCCAR for some time. Obviously the mil spec kit would have to be replaced for civ and I guess the biggest impact will be in the avionics.
It was certified as a civil aircraft first before clearance of military specific roles and equipment. Possibly, the test aircraft had mil kit to make the MEL such as radios and transponder under exemption if necessary, rather than civil only equipment to be replaced by the customer specific equipment later on.
I just did some structures calcs on the wing so am not in the actual knowledge here...just what was talked about in the office at the time.
