Hi there
The BEA report states:
"The tail fin was damaged during its recovery and transport but the photographs available made it possible to identify the damage that was not the result of the accident. The middle and rear fasteners with the related fragments of the fuselage hoop frames were present in
the fin base. The distortions of the frames showed that they broke during a forward motion with a slight twisting component towards the left." (p.35).
On another hand, it is said that most of the debris suggest a strong vertical decceleration and the action of strong compressive forces:
why don't the middle and rear fasteners of the VS with the related fragments of the fuselage hoop frames (who suggest a forward motion & slight twist) show this strong compressive structural effect ?
That the connecting brackets between the floor and the walls were bent
backwards also suggest an horizontal acceleration component ? Shouldn't the thousands of vertical Gs of the vertical impact on the belly have compressed the fasteners and fuselage hoop frames in the same way ? Why only a foward motion with a slight twist is seen on the VS ?
