Repairing plaster ceiling

As you can see in the photo, the plaster on this ceiling is cracking, and in some places has started falling down. I pulled away most of the loose plaster to reveal what I am guessing is the "brown coat". It is a very gritty/sandy brown surface that is hard but seems hollow behind it. I don't know if it is clear in the picture but most of the ceiling is covered in small cracks. I think it is only a matter of time until it all starts falling down.

Suggestions? This is a rental property and it is the ceiling above a loft area only used for storage (the ceiling is about 4ft high up there).

Will pulling down the loose plaster around the hole and putting a new finish coat over this area work? I feel like the brown coat is so sandy that it might not adhere well. Just brushing my hand across the surface makes the sand come loose.

I'm not a plaster guy but when I get stuck making a repair on something like that, I prime the brown coat to bind up the sand and then use durabond inplace of plaster.

I'm sure one of our plaster pros will be along later with the correct way to fix it.
