No idea what they were thinking...
The final report is chillingly clear. PF startled by the aural warning and all the blue on the PFD instinctively pushed the nose down without thinking. PNF seeing correct display was totally out of the loop on why. All this in the small hours on a 5th & last leg, with cockpit lights on for the approach briefing during a pitch black night with zero outside visual references. By the time they started to get their act together the situation was beyond recoverable.
Yes, I read the report and my initial thought was: What were they thinking?: Right side agreed with the St.by instrument. Fly the right side, ignore the left side.
Pretty basic, but yes, I understand they were tired, lights were on, etc, etc.
Well, too late now and there is lessons to be learned here: Same as in basic training: Fly the good side, don't rush too into action, etc.
