There are always more things that are going wrong than the official things that you get "busted" for. There always have to be official things that you messed up to bust a ride. That is what goes into the paperwork. What really costs you the bust are the small things that add up. The general sense of you having no idea what you are doing, lack of overall proficiency, and general feeling that you are not safe in the airplane yet. Those are what really causes an APD's hair to stand on end and start watching much closer.

As all examiners know, it isn't the students that you bust that keep you awake at night, it is the student that you know you should have busted that you let pass even though they should not be in the airplane yet.
