Do they need to remove the seats and pull the floor to inspect the frame? That alone is labour intensive and put the cars out of service.I've been hearing rumours for a decade that there's big concerns about the potential failure of the main longitudinal aluminum structure (there's a word they use ... beam?). I wonder if that's why some are being pulled from service. If it becomes too widespread, I'd think they'd have to permanently withdraw the entire fleet.
Such things do happen. But if they start seeing catastrophic failure of the aluminum structure, I'd expect they'd all be pulled, or very closely inspected.
Can some be fixed if they are not in bad condition? Bracing?
