How to make a dragon fail landing/crash on the ground/fall from the sky ?

I don't mean Dragonrend.

I mean when a dragon falls from the sky and land badly, in a way they stop attacking for some seconds while they recover, when this happens, they usually make changes on the land around them, though, you can actually walk through the dirt the crash landing makes.

Example of crash landing:

How do I make this happen?

I've heard that shooting them in the wings may cause this, or does this just happen when it's on low health and in the air?

What actually triggers the crash landing?

You just need to do a bit of damage.

Once the dragon has been injured to a certain extent, usually after half of its health has dropped, it will remain grounded.
