Oh a typo.. yes it should have been AD..
But i stand by the point made, every aircraft built has had defects that have needed rectification while in service.
I see this thread being another Boeing V Airbus fight? Lets not guys!!!!!!! Both have good and bad points..
How many AD's have been issued for 737? 747? 757? etc and compare that to the amount issued for A320/1? A330? A340? etc I bet you'll find its very similar number each?
The main thing is that they are being found on both types and lessons learnt designs changed. If not thats when you get worried.
