Does the Track (heading) FR24 granular data yield any clues? [graph
* It was cruising at 100º.
* As soon as the rapid descent began, it starting veering to the left to 91º in the first 20s. The descent rate was around 30,000 fpm.
* The next 15s, it veered the opposite way to the right to 140º. The descent rate was still around -30,000 fpm.
* The next 25s, it veered the opposite way to the left to 81º. The descent rate was slowing down and reached 0.
* For the final 50s, the track was relatively stable between 73º-88º.
Does this either support or eliminate any theories?
One possible scenario:
* Starting the descent triggered a mechanical failure which caused the plane to roll left initially.
* Pilots compensated with a procedure that caused it to turn right, but it was still dropping at -30,000 fpm.
* Pilots tried something else that was able to recover the plane, reaching +8,400 fpm and 8,600 ft AMSL, and stable heading.
* May have stalled at 8,600 ft AMSL, and didn't have enough altitude to recover. Or the recovery put too much stress and caused additional mechanical failure.
