From some of the comments from people who flew the ATP most of them I see are quite underwhelmed. From a maintenance point of view I can only pick out a few words a previous poster used to describe it. I think he wrote that it is a heap of junk. I think he summed it up very accurately. Most aircraft have some parts that maintenance engineers do not like, but the ATP beats them all hands down. It is a truly awful awful aeroplane to maintain. I think the designers must have looked at all the developments in aviation over the previous decades, and decided to ignore them. There is a well known phrase amongst maintenance engineers which is, " it's not broke, it's British". That about sums up the ATP.
