Just relooked at the NTSB report and I'm surprised there is not more mention of what state the AFCS selector panel was in - should have been possible from bulb filament analysis.
I don't think it was in the final report, but from the materials report: "No bulbs were found in the AP1 ON, AP2 ON, COLL RAD, FD2 and SAS/ATT annunciators."
