I very much doubt the AOC would be suspended, as there isn't anything to base that decision on. Poisoning your crews is not a matter the CAA would want to go near. If the paperwork was hooky, then they'd be interested, but this. I don't think so.
The last company to have its AOC suspended was Emerald and that took years of blatant breaches before the FOI actually did something. Unless of course after that debacle the FOI have finally got some teeth!
