This "new prototype" is actually a commercial failed plane which is out of production for a few years. The only major operators are in Europe; Swiss, Air Botnia of Finland and Regional of France. Esp. Swiss would be happy to sell a few for a bargain, but I don't think the plane is as well suited to dusty and short airstrips on which the F-27 can operate, and also it would be hard to set up the maintenance for such a rare bird no one else in the region flies (just like the few ATPs in Bangladesh and Indonesia which were quickly disposed off). I guess PIA will pick up some DHC-8s or ATRs in a few years time.
nobody has ever died from hard work, but why take the risk?
