1. The aircraft suffered a fatal accident.
2. Media reports hint at unofficial industry sources which allude to the loss of thrust from 3 or more engines at low level during the intial climb.
3. The reason for this rumoured loss of thrust has yet to be officially identified.
4. FDR and CVR analysis is ongoing.
Excellent summary. I would add the following:
3. The reason for this
rumoured loss of thrust has yet to be officially identified,
but the same rumor sources claim it was due to a fuel tank trimming system unique to this specific aircraft and not previous installed on A400s.
It is this last item that started the discussion on FADEC and ECUs, which are likely not involved in a fuel tank trimming system anyway.
