What is the cost of a hinge repair on a MacBook Air (Retina, 13-inch, 2019) with standard AppleCare?

Hi there.

I have a MacBook Air (Retina, 13-inch, 2019), and its hinge is beginning to loosen up on me. The screen still stays open of course, but, at certain angles, the hinge will no longer hold the screen in its place (for example, when the screen is half-closed, the screen will accelerate down into the keyboard). I have a standard AppleCare plan.

What would be the cost of repair? Aside from this hinge issue, my laptop is in great condition, so I would like to keep it going as long as I can, and I think catching this issue in its early stages will prevent more serious damage in the future.

Thank you!
