That's kind of what I'm guessing. I doubt the FAA has scores of replacement parts for an entire communications center.

Apparently, there was fire damage, then water damage from the sprinklers.

In my Air Force experience, I was often surprised to find out a frequency would be disabled at a base because they didn't even have ONE spare radio!!

Magnify that by dozens of radios, comm lines, and the interface for 40 or 50 radar scopes...
