As has been said to much hinge. I sold all my ash, 4 tri-axle loads. The first tree I sawed I did the same thing. Goods news it was the only one, had one with a nice fork that split back when it hit.

Too much hinge. on a nice ash sawlog I ussually leave around and inch plus or minus, bore out the center through the face and nip the "ears" on either side of the face. As much wood as you can take out however you can without compromising the fall direction is a good rule for high grade hardwood falling.

Too thick hinge for sure.

Good rule of thumb for holding wood (hinge) is 80% diameter of tree in length and 10% diameter of tree in thickness.

10 tree=8 long and 1 thick
20=16 and 2....etc.

I agree with the hinge being too fat. Iwawoodworker mentioned something I've done a few times if I'm worried about it barberchairing. I've wrapped a heavy chain around it above the cut so that if it does split it can't throw. The concern in my head then is that the chain is heavy enough not to become the problem if it splits.

Don P. I have done that too if Im pulling a heavy leaner over or something like that.  Will use chain and chain binder of HD ratchet strap.Works really well.

 One other problem is I think the tree was froze also. Ash and hickory when frozen are harder to judge the hinge.

Cut up a couple five foot lengths and milled today. Pleasantly surprised. Btw my local forester tells me this is still White Ash.

Well, i don't see a fail, either for firewood or sawmill! :D 
It's a nice slab, split perfectly on the quarter; which, if well sawn and advertised as such, could bring a premium.  And if it's for firewood, well, look at it, as less splitting work to  do! :D

The main thing is the hinge is too thick that caused the chair. To the face myself I would of been shooting for a deeper face roughly about the middle of your hinge, when putting in your face the depth as well as the angle of the face have effect on the tree in this case Id say both helped the tree chair. An open or even a block face allow the hinge to bend instead of break which is great for staying on the stump not so great for a chair situation. Im not a huge fan of boring a back cut Ill use a coos cut on a leaner or standard back cut everything else.

When I took my GOL (game of logging training) I was taught to make the hinge 10% of the diameter and the face cut in about 20-25%. Then do the plunge cut, about in the middle between the hinge and the back of the tree about 2-3" higher. Then bring the hinge to the 10%, in this case, 20" tree, 2" hinge. Then it in doubt, do a plunge cut directly in the back and drive a plastic wedge. If still in doubt use the chain or heavy strap idea to help hold the trunk from splitting. That wedge is not needed in the back if the tree has any lean in the right direction. Then cut from the hinge out the back. And as you did, as soon as the tree starts to tip, run 45 degrees away from the tree, but keep an eye on it to be certain it is going away from you, but not straight away.
As others have said, ash and a few others are prone to split, so that would be a good time to use a heavy strap or chain.
Any tree that you drop that gets no body or anything valuable hurt is a success.
