Something I noticed tonight as I was reading through, that I hadn't noticed before in the pictures. The very straight line of the break on the left side of the tail, compared to the more can opener style of damage to the bottom and right side.
Would a crack lead to such a straight break?
I wouldnt think a crack would propogate in such a straight line, but a straight line in a crash where everything else looks like a beer can seems odd to me.
If my blade directions are right, if something,(crack, harmonics like the picture above, FOD denting the tailboom?) caused the tail to weaken, the tail rotor would fold the tail to the right like the accident sequence?
