Had tangage +1...+2. Which means was rising.
Tangage is the French word for pitch.
I do not know the pitch attitude the TU-154 would use on approach, but a bit of nose up is common on jets on approach.
Of course the evidence of the trees shows a slight climb from the initial impact. The crew may have been making a modest altitude correction and may not have been aware of the initial contact(s).
At the reported 150-180 m/sec, there would have been >= 1.5 second between the two trees.
While these initial impacts may not have incurred major structural damage, hydraulic, electrical and pneumatic runs may have suffered damage at these points that compromised further flight.
