If you are considered unsafe to hold a CPL, then surely that applies to a PPL, an RAAus PC, and any other flying qualification?
The word "unsafe" is probably not correctly used in this instance Pots. Paperwork / AOC breaches etc wouldn't necessarily constitute the loss of a PPL. An RA cert could be lost if the RAA determined you to not be a fit and proper person and deny you membership. Would have to be pretty severe for that to happen.
