It's the engine thrust...nothing more
Clandestino - If you will look at the FDR traces in the latest report, you will notice that at 2:11:45 the pilot had full nose-up sidestick inputs, the THS was in the process of moving to full nose up and the aircraft was fully stalled with a nose-up attitude of about 15 degrees and an AOA greater than 30 degrees. A few seconds later, the N1 falls off, bottoming out at about 2:12:07 around 60%. During this time, PF had the sidestick full back and the THS was almost full nose up BUT the attitude decreased from 15 degrees nose up to 10 degrees nose down in about 10 seconds.
Later, at around 2:14:05, with both sidesticks in full back (nose up) and the THS at full nose up, a decrees in N1 reduced the pitch from 20 degrees nose up to 5 degrees nose down. For me, this proves what was keeping the nose pitched up was the thrust not any flight control inputs or the THS because EVERY time thrust was reduced, the nose fell despite the PF actions (inputs and THS).
Every other instance where the nose started to fall were control inputs showing even with the full thrust, there was enough control to get the nose down.
