History
The King Air 300 is an updated
version of the successful B200
series, and it itself was
replaced by the further improved
King Air 350, the latest model in
this long running and successful
line of corporate and utility
transports.
Design of an improved development
of the successful King Air B200
began in August 1981, the 14
month design effort culminating
in the first flight of the
modernised 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 reprofiled
and 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 300LW or `Light Weight',
intended to minimise 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The King Air 300 has been
replaced by the 350, its major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 (2ft
10in) 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. The King Air 350C features
a builtin airstair and a 132 x
132cm (52 x 52in) freight door.
The 350 is also available in a
range of special missions and
military variants.
The `Super' prefix was dropped
from the King Air name in 1996.
