I used to work for a company that used AAN's certificate. I really liked those guys, and it is my belief that they really tried to run a tight operation. The problem was that every lowlife operator in the country flocks to certificates for hire so they can operate with little or no oversight at their home base. These POS operators generally hire cowboys for operations and cheats for maintinence.
There was only so much they could do to oversee more than 50 aircraft and their crews from St. Louis. I have been saying for a long time that piggy backing on certificates likely will be outlawed sooner than later. It looks like it is coming sooner. I hate to see trouble like this come down on Doug and Steve, though. If ya'll are reading this, take care!
