This seems to match with the FDR data where only INB Ailerons were solicited at a max deflection of 16 degrees out of 25, and spoilers 4 and 5.
After PRIM and SEC1 were turned OFF, only spoilers 4 remained active. I suppose the zipper shape for spoilers 5 and 6 show their inactivity related to PRIM and SEC1 status.
Another hit at the BEA :
Why no further comment on the PRIM and SEC1 episode, especially in regards to the human factor analysis ?
IMO, this one clearly indicates that the crew (or at least the PNF) lost faith in the aircraft, and probably thought they were facing a computer bogus, or a protection takeover.
