Is an Airbus A319 allowed to fly with a missing flap track fairing? During a recent flight from Copenhagen to Milan in an Airbus A319, one of the flap track fairings were missing from the wing. I saw this during takeoff, and notified a flight attendent as soon as the "seatbelts on" sign was turned off.



She seemed slightly surprised and went to the cockpit (supposedly to tell the pilot). After some minutes she returned and told me that it was fine, the captain had seen it during inspection and it was noted in the log 

Is it normal procedure to take off with knowledge of missing flap track fairings? What are the consequences of one missing?
Fully permitted according to this Configuration Deviation List for the A320:


  One fairing may be partly or completely missing.




There are more posts about this occurring. As Noah Krasser points out, it looks fairly dodgy to observant passengers. This is the "Master" list, i.e. the safe and approved baseline. Some airlines may have changes in their own internal documents not to dispatch aircraft in this condition at all.
