Which on Rwy 29, means a Xw comp.= c.ca 8G12 Kts. Not a big deal.
AC, after reaching alt of 700m, started to descend with negative pitch angle, that reached -75 degrees at the end of the recording. AC came into contact with the ground at high speed (more than 450 kmh ) and with large negative pitch angle.
From the moment of GA to the end of recording 45 sec had passed and the descend took 20 secs From the moment of GA to the end of recording 45 sec had passed and the descend took 20 secs.
From 700 m (2200 ft) to zero in 20 secs, means 6600 ft/min???
Given that the stabilizer was almost for sure, as usual in that phase of flight, toward the final end of ANU, as soon as the plane had regained a bit of speed would also have had a strong pitch up moment.
The only maneuvers I can imagine for a plane to assume such an attitude are:
- A spin (to which would favor the low speed and the high rate of descent)
- An Hammerhead
- A loop
And since the last two above mentioned manoeuvre have to be excluded, only one possibility remains:
The loss of the elevator or the whole tail separation.
My two cents
