That's Interesting however id be curious as to the source of the documents mentioned.
Looking at the official KNKT Preliminary Aircraft accident invesitigation report
https://reports.aviation-safety.net/...RELIMINARY.pdf
If you look at page 11 with regards to the CVR transcript you'll note that the SIC (co-pilot) confirms to ATC that the aircraft is being flown manually due to a flight control problem, that was 2 mins and 17 seconds before impact.
