King Air 300 Medium-Sized Prop


King Air 300 Turbo Prop

The King Air 300 is an updated version of the B200 series and has since been replaced by the King Air 350, the latest model in this long running and successful line of corporate and utility transports. 

Design and improved development of the King Air B200 began in August 1981, the 14-month design effort culminating in the first flight of the modernized 300 model in October the following year. Improvements to the B200 were many, with the main change being the installation of more powerful PT6A60A turboprops in place of the 42s of the earlier model. Other changes included more aerodynamically clean engine cowls and exhausts and extended wing leading edges, plus minor internal changes. Both empty and max takeoff weights were also increased. 

The max weight was reduced for the 300, intended to minimize the effects of weight based airways user fees, particularly in Europe. The 300AT was an airline pilot trainer. The King Air 300 has been replaced by the 350, its major improvements being a stretched fuselage lengthened by 86cm (2' 10") and the addition of winglets. The latest member of the King Air family, it had its first flight in 1988 and has been in production since late 1989.
