I'm sorry but we don't all "truly" know it was the FADEC. Like most other conjectures (well informed or otherwise) on this accident.....there is (as yet) insufficient evidence (just as there was in an earlier Mk1 accident in the Falklands) to draw "true" conclusions.
As for the FADEC....amongst other issues associated with it, one might ask about other examples of MK2 FADEC runaway in flight - and note I said flight....anyone got a contribution to make?
Cheers
