In Flybe service the Q400 has done not a lot worse than the original Dash 8--i.e. a difficult first year but a steady improvement as experience by all concerned was gained. The flybe ac were always to a later standard than the SAS deliveries, and many tweaks have been initiated by the flybe team--after all flybe is the Bombardier service centre for the aircraft in europe.
This weeks events were due to 3 unrelated problems--tiresome but not any particular impediment to have the aircraft up to a proper Dash 8 reliability figure by the end ot the year which is the stated aim.
