It seems to me that DAS is making the wrong point here, focusing on the lack of notice time. If (disclaimer 1) their aircraft or procedures did have serious deficiencies and if (disclaimer 2) they were informed of these by Dutch and /or German authorities repeatedly in the past, than there is no reason for a grace period before a ban finally comes into affect. Does anybody have any factual information on what discrepancies were found in the past, where and how often?
