Air West Coast made the newspapers a few weeks ago shortly after the fumes in the cockpit episode. CAA were on their case because they suspected the aircraft was being operated outside the operators certificate - in that the airline and/or the pilots weren't licenced to operate a 19 seater.
In other words, the need for those at the coal face to hold an ATPL.
AWC came back to say that all flights performed in the Dornier were done on a 'promotional basis'.
CAA were keen to find out how much the passengers had paid the airline to be part of the 'promotion'.
As a result, we haven't seen the Dornier since. She'll be a useful addition to the fleet when everything is up and running.
