Beechcraft 1900

The Beechcraft 1900 is a U.S made twin-engine turboprop regional airliner manufactured by Beechcraft. It is also used as a freight aircraft and corporate transport, and by several governmental and military organizations. With customers favoring larger regional jets, then-owner Raytheon ended production in October 2002.

Developed from the Beechcraft Super King Air, the aircraft was designed to carry passengers in all weather conditions from airports with relatively short runways. It is capable of flying in excess of 600 miles (970 km), although few operators use its full-fuel range. In terms of the number of aircraft built and its continued use by many passenger airlines and other users, it is one of the most popular 19-passenger airliners in history.

The 1900 is Beechcraft's third regional airliner after the Beechcraft Model 18 and Beechcraft Model 99 Airliner.

The Beechcraft 1900's design lineage began in 1949 with the Beechcraft Model 50 Twin Bonanza, a 5-passenger, reciprocating engine utility aircraft designed for the U.S. Army. A larger passenger cabin was added to the Twin Bonanza's airframe, and called the Model 65 Queen Air. This aircraft was, in turn, further modified by adding turboprop engines and cabin pressurization, and named the Model 90 King Air. A stretched version of the King Air was later developed and designated the Model 200 Super King Air. Beechcraft developed the 1900 directly from the Super King Air, in order to provide a pressurized commuterliner to compete with the Swearingen Metro and the British Aerospace Jetstream.

The 1900 first flew on September 3, 1982, with Federal Aviation Administration (FAA) certification awarded on November 22, 1983, under Special Federal Aviation Regulation (SFAR) 41C airworthiness standards. Like the 1900, the 1900C was certified under SFAR 41C, but the later 1900D version was certified to FAR Part 23 "Commuter Category" standards.

The 1900 entered service in February 1984, with the first ExecLiner corporate version delivered in 1985. A total of 695 Beechcraft 1900 aircraft were built, making the airliner the best-selling 19-passenger airliner in history. In 1991, the price of a 1900D Airliner was $3.95 million. With market trends favoring larger 50- to 90-seat regional jets, Raytheon ended production of the Beechcraft 1900 in October 2002.^{[citation needed]} Many airlines continue to fly the 1900.

Since the 1900 is derived from the King Air, all 1900s share certain characteristics with that aircraft. Cockpit controls and operations are similar to those of the King Air. The aircraft's noticeable deviations from the King Air comes from its longer fuselage and the presence of "stabilons", which are small horizontal stabilizers at the rear of the fuselage for overcoming T-tail blanking when the aircraft is in higher angles of attack. Additional fins for yaw stability were installed on the tail for 1900Ds, which also feature a taller cabin to allow for a "stand-up cabin" with more walking headspace like conventional airliners. While Federal Aviation Regulations require two pilots for passenger airline operations, the 1900 is designed and certificated for single-pilot operation in corporate or cargo settings, as is the King Air.

The 1900 is powered by two Pratt & Whitney Canada PT6A turboprop engines. The 1900 and 1900C use two PT6A-65B engines, each flat-rated at 1,100 shaft horsepower (820 kW). The 1900D uses two PT6A-67D engines, each rated at 1,279 shaft horsepower (954 kW). The propellers are manufactured by Hartzell, with four blades on each propeller. The blades are made from composite materials.
