They were a great aeroplane for their time, but by today’s standards extremely - and I mean extremely - noisy.
Also not fuel efficient, though right now that would not matter, but when fuel gets expensive again it would never compete with ATR or DHC.
Terrible in the summer due to lack of on ground air conditioning.
Most gone to scrap now, or 3rd world, or a few stripped out for freight. Plenty of cheap more modern alternatives parked awaiting new owners. Even the later F50 which was supposed to compete with DHC and ATR is obsolete, even though many would argue it is the more robust airframe. Problem is robust equals weight equals fuel and payload penalties.
But F27 a joy to fly, though ground handling took finesse.
