Yes, any airline can have problems introducing a new type to service. But, it has taken an inordinate amount of time to get these a/c into regular service; & to replace the BN3 - both of which have not happened yet. Then, there are the continuing stories about the various Doernier a/c - not all of which can be totally untrue. Has anyone forgotten the saga of the original lease of the Portuguese a/c ? - which also seemed to go on forever, without much, if any, explanation.
Is there any chance of a definitive answer to all the questions ? Probably not; at least, not from AUR !
