There are now several pics of the damaged tail section which **seem** to show the coupling between the jackscrew and HS- sort of an 'H' shaped part normally attached by large pins on left and right sides. *post 1317 and 1004 for examples *
What bothers me is that that part visible in the wreckage does not seem to be broken, ie: the 'ears" on the ends of the 'H' section seem to be undamaged. Which in turn means that the pins were pulled out in the reverse direction of normal installation.
Those pins are massive compared to other parts, and the "H" section is probably a machined part. Given the expected tumbling and impact damage of the tail section evident- it is IMO dfifficult to understand how at least two pins on the legs of the "H" either fell out or were removed without any obvious sign of damage. ( ears not damaged, pins or portions of pins not evident )
Could it be that the pins/jackscrew parts were removed by ground personnel before any of the released photos were taken ?
OTOH that 'H" shaped part is *probably* not part of or related to the jackscrew at all - it does appear to be relatively thin. ??
NOTE added see post 1308 claiming H shaped part is of APU flap door assembly. Even so- how to explain removal of 'pins'/'links' ????
