CASA has decided to shut Angel Flight down. That much is obvious.
The method chosen is called "File stuffing". That too is obvious.
The method involves starting a file on the activities of Angel Flight and recording and filing detailed observations of any infraction of any rule by an Angel Flight pilot.
Make no mistake, CASA are out to get Bristow. The initial "discussion" paper was actually a call to arms to every flight operations inspector and airworthiiness inspector in Australia to redouble and triple scrutiny of every pilot and aircraft in the Angel Flight fleet.
To put that another way, The "meta message" - the message you are sending when you dont say you are sending a message is simple; CASA thinks Angel Flight must be closed and it is the duty of every CASA employee to make it so.
When the file reaches about Four inches thick and another incident occurs, say a wheels up landing somewhere, CASA pounces. The pull out the file and thump it on the tale saying "the contents of this file PROVE Angel Flight is a safety menace and the minutiae of all the reports of flat tyres, out of date charts, unrestrained baggage and missing spare spectacles are simply too voluminous to defend in detail and you are f^&%ed.
Why is Angel Flight under attack? Simple,, it is building enough community support nationally to attain the status of a national Icon, and if that happens CASA can't attack it any more than they could the Royal Flying Doctor Service or Bondi Surf club without a national outcry.
CASA may have left its run too late though if Angel Flight, realising that it is now prey, decides to build its public profile.
