Better than that. In BEA IR #3, there is a picture of a recovered Flap rail that was EXTENDED. The "Extended" was in their caption, it is not my conjecture.
Hypothetically, since S/F trace is U/A, it cannot be ruled out that that is exactly how the Rudder was reinvigorated after RTLU instant at a/p loss.
A hint? RIGHT ROLL, the bias is apparent from the outset, and cannot be explained. He had extended the brakes, and stowed them, and the evidence is unclear that all were successfully stowed at deselect.
For that matter, it is not impossible that one or more spoilers was lost in the air.
Find the pic, and see what you think. F1 is possible, eithwr as a STALL recovery memory item, or as a desperate attempt to gain control, or lose a/s or Level out, or......
