For goodness sake what is with the quoting all the time and the nitty picking at comments.....the Q400 is a great little aircraft. Remoak all you have to do is look at the number of flights operated daily (too many for me to quote) and you can see that it is as reliable as any other aircraft.
It has had a few minor niggles which if maintained poorly will continue to affect the aircrafts performance. If maintained correctly however there is no reason why they cannot perform to a high standard albeit with the odd tech issue which I think you will find can cause disruption with any aircraft type be it prop or jet.
Lets move on to something else, I cannot help feeling that this thread has past its sale by date
