The CAA are historically rubbish at enforcing anything company wise. They'll jump on individual pilots as quick as blink, but companies, no.
I once had reason to "discuss" with them a UK scheduled airline that ran a fleet of 5 aircraft none of which was fit to fly for fundamental maintenance-related reasons and had documentary evidence to prove it. They - or rather the Flight Ops Inspector involved denied that the CAA had any right to spring a surprise maintnance audit or to investigate the matter and nothig was done. A number of similar reports from others over the years has apparently had similar (non) effect.
Ther may well be issues of responsibility among the overseers of the company's CAA licences who would not wish it to become known that this had been going on undetected under their remit, causing questions to be asked about their efficiency in overseeing their charges...It could be that they just don't want questions asked about their own eficiency and it's easier to turn a blind eye and simply deny their existence, like the police often do with problem crime crime areas.
