The Beechcraft 1900D
aircraft is clearly the best 19 passenger airliner in the
world. It offers the best operating value, the best dispatch
reliability, the lowest number of maintenance hours per flight
hour, unsurpassed seat mile cost and superior long-term value
offers a true stand up cabin (71 Inches tall) and an extra
generous cabin volume which allows seating for everything from
a 19-seat executive shuttle to a 12-place triple club
corporate flagship. No other aircraft in its class can carry
so much, so far, so fast.
While the Beechcraft 1900C
had become a popular regional airliner, Beechcraft
undertook a substantial redesign of the aircraft, and in
1991 introduced a new version called the 1900D.
The 1900 and 1900C,
like most 19-passenger airliners and business jets, have
fairly small passenger cabins, with ceilings so low that
passengers cannot walk through the interior without
bending forward. The 1900D was designed to remedy this
by providing a "stand-up cabin," which would allow most
passengers to walk upright. It is the only 19-seat
airliner with this feature.
Because the taller
passenger cabin adds both weight and drag to the
airplane, other elements of the 1900D were also changed.
More powerful engines and modified propellers were
installed, winglets were added to reduce drag and
increase the wings' efficiency, and the tail was made
larger in response to the more powerful engines. The
cockpit was updated with an Electronic Flight Instrument
System (EFIS). The 1900D was certified under the
then-new FAR Part 23 "Commuter Category" standards,
which had replaced the earlier SFAR 41C. Since the UD
serial numbers were already in use by the military
1900s, the 1900D airplanes have serial numbers beginning
with UE. The 1900D is the most popular version of the
airliner, with 438 of the 1900D built.
