The DHC-6 Twin Otter and the Dornier 228 (now called Do 228 NG and manufactured by RUAG) are still in production. They are in the same 6-ton class as the larger KingAirs. There are a few more twin turboprops in the utility category / light military transport being produced somewhere in the world. This category of aeroplanes is not dead yet!
It may not be dead, but better improve over the 4 turbine setup in the Airbus A400M ;-). Where was that stuck with engine outage lately, Lithuania?
