That was my understanding. I can’t follow what 4Runner is trying to get to.
On a closer reading of the factual report, I noticed this on page 10.
About 16 seconds after the Captain told ATC “OK,” the FDR stopped recording data with the airplane descending at an airspeed of about 433.5 knots and the autopilot engaged.
So during the whole episode, with split elevators and all, the AP remained engaged? Was it the AP that commanded the pitch down to 50 degrees?
They had recently (apparently) resolved an instrument problem. Is there a scenario where the ADI would be indicating a nose up pitch (leading the FO to believe they were in a stall) and the AP would aggressively command a nose down pitch?
I didn’t see where the report mentions which autopilot was engaged. Could the engaged autopilot somehow have been getting bad info that was not captured by the FDR, or noticed by the crew after they addressed the instrument problem?
