That is an interesting bit of damage. It appears as both a compression and torsional deformation, which hints of the same sorts of loads that occurred with the Ethiopian B767 off the Comorros. In that case, the stabiliser hits the water early on (just after the wingtip, and has an large asymmetric loading from the left stab being in water, the right stab being in the air, and tears the tail off in torsion. This looks like the load at PTKK was upwards at the tail and towards the right, there may have been a pretty good body angle at impact putting the stab into the brine early in the impact sequence. Lucky though, the distortion of the tube doesn't look like it was severe from the video inside taken by the USN.
