Yeah, I am based in CPS with AN, well I was until yesterday, now i'm headed for MEM. I hear them constantly in the morning leaving while I am coming home. I have heard nothing about engine problems, but I do know that they do not have the brightest pilots flying out of CPS. The other night one of their guys had a radio problem while number one for the runway. He was trying to get his clearance, but obviously couldn't, so instead of moving out of the way for two AN aircraft, one being myself, and another of his company, he decided to sit there for upwards of fifteen minutes delaying everyone. It is kind of hard getting a clearance from an RCO while another guy is busy blocking the frequency having troubles. Needless to say both myself and my company lear were both late to our destination thanks to a pilot who didn't consider everyone else waiting. I am sure that most of their pilots are not like this, but as PIC you need to think of other things around you as well as what you are doing.
