Small incident.
What I find far more interesting is to see ( in another article ) that tickets for the flight Dresden-Zurich is done by Etihad Regional (from the UAE) with an aircraft painted in Etihad colors but operated on paper by Darwin ( a Swiss airline which Etihad bought 33%) but in fact the aircrfat belong to Avanti , a German company specialised in wet lease. Avanti has only 2 aircraft , the ATR in question and a FK100 which is not yet flying .
I wonder who is regulating the maintenance.
