GB, I wasn't thinking about the engines being involved at all: my thought was that the FADEC data could lead to learning at least what the collective was doing. .
Should have added that I’m certain that SA is assisting the NTSB,and they will certainly be chasing down any possibilities re data that might be obtained from either the engine Fadec or the Honeywell AP box. The crash photos makes that hope a bit optimistic but its a box you have to check-literally.
