For Qavion. You are right I guess, as i said its been a long time. I am confusing the problem with one where the hydraulics are not fully operational, which causes the outboard spoilers to come up ahead of the inboards, and so the pitch up.. It can be very pronounced.
Sometimes it did it even with auto spoiler and everything normal, which leads me to believe there is a sequence and if that sequence is upset, the nose will pitch up on landing.
