A Timeline of the King Air
Nearly 6,000 Beechcraft King Airs of 17 variants have been sold since the product line was introduced in 1964, making this the most successful series of twin turbine-powered business aircraft ever built. The aircraft fly in corporate, commercial and special mission operations in more than 94 countries throughout the world, and the King Air fleet has accumulated more than 40 million operating hours.
The following milestones tell a story about one of the most popular aircraft in the world – one that is continually updated with the most recent technological innovations. Competitors have come and gone, and the King Air keeps flying. Owners and pilots understand that this is a very versatile aircraft that can perform practically any mission required.
First flight, Jan. 20, 1964

Featuring twin Pratt & Whitney PA-6A-28 reverse-flow, free-spool turbine engines rated 680 horsepower each, the 100 cruises at 287 mph and offers overall performance greater than the Model 90.

King Air C90
Sept. 29, 1970 – First flight of the Model C90. With a wingspan of 50 feet, three inches, the PT6A-20A turboprop engines developing 550 shp for takeoff. Empty weight was 5,680 lbs. with a gross weight of 9,650 lbs. Seating six comfortably in its pressurized cabin, the C90 cost $399,500 including complete anti-ice/deice equipment and avionics. Maximum cruising speed was 253 mph, initial rate of climb 2,000 fpm and the C90 could reach a service ceiling of 25,600 feet.
1971- The Model A100 King Air replaces the Model 100. Basically an advanced version, the A100 features a 900-lb. increase in maximum takeoff gross weight to 11,500 lbs., carried an additional 96 gallons of fuel that stretched range to 1,542 statute miles at an altitude of 21,000 feet. Four-blade propellers with shorter span improved ground clearance during taxi and landing operations. The A100 cruised at 271 mph at 21,000 feet and could climb to a service ceiling of 24,850 feet.
1971 – The U.S. Army purchases five Model A100 King Airs to serve as pressurized transports designated U-21F.
Jan. 18, 1972 – first flight of the Model E90. Mounting PT6A-28 turboprop engines of 680 shp flat-rated to 550 shp, the Model E90 was very similar to the Model C90. Pressurization remained the same as C90 at 4.6 psid but performance increased with a cruise speed at 16,000 feet of 285 mph and a service ceiling of 27,620 feet. At maximum range power setting, the E90 could fly 1,870 statute miles.
The Model 200 serves as the platform for many of the world’s special mission aircraft
Oct. 27, 1972 – First flight of the Model 200 Super King Air. After four years of research and development, Beech introduces the first T-tail King Air, which would go on to become the best-selling King Air of all time. Wind tunnel testing of the tail itself consumed 375 hours. The distinctive T-tail raised the tail out of the wing’s downwash, allowing the stabilizer and elevator to operate in relatively smooth, undisturbed air. The Super King Air was powered by to P&W PT6A-41 turboprop engines rated at 850 shp each, and could deliver that power up to 106 degrees F. The aircraft carried 544 gallons of fuel in wing/nacelle tanks and two auxiliary tanks located in the wing center section that was two feet wider than the A100’s. Wingspan increased to 54 feet, six inches, length 43 feet, nine inches. With extra power and wingspan, the Model 200’s maximum takeoff gross weight was 12,500 lbs., useful load 5,275 lbs., and maximum speed was 333 mph. Model 200’s cabin seated up to eight in typical King Air surroundings. Air conditioning was standard along with complete wing/tail/propeller deice and windshield antiice equipment. The Model 200 demonstrator, N200KA, carried the name “Free Enterprise.”
1974 – The first Model 200s to enter military service is designated Model C-12A, and ordered by the U.S. Army and U.S. Air Force.
March 20, 1975 – First flight of the B100 King Air. Beech engaged a secondsource supplier of engines for the successful Model A100 King Air with new Garrett AiResearch TPE-331-6-251B/252 fixed-shaft turboprop powerplants. Producing 840 shp flat-rated to 715 shp, the TPE-331 gave the B100 a maximum cruising speed of 306 mph, with a cabin altitude of 8,000 feet at 21,200 feet. Range was 1,501 statute miles.
1976 – Beech modifies a Model 200 Super King Air for special mission use. The 200T comes equipped with 50-gallon wing tip tanks for increased endurance and range. Designed for maritime patrol, the aircraft features special large, bulged observation windows in the aft cabin section, surveillance radar housed under the fuselage and a lower fuselage fairing accommodating various photographic equipment for reconnaissance purposes. Electronic control and monitoring consoles are installed in the cabin.
F90 King Air
Jan. 16, 1978 – First flight of the Model F90 King Air, conceived as an advanced version using a Model E90 fuselage and wings combined with the Model 200 Super King Air’s swept T-tail empennage. Intended as a step-up King Air from the E90, the F90 was equipped with two 750 shp PT6A-135 turboprop engines, seated seven to 10 occupants (including crew) and cruised at 307 mph. To reduce noise level, the four-blade, constant-speed, full-feathering, reversible propellers turned at a maximum 1900 rpm or 1500 rpm for cruise operation. Initial rate of climb was 2,380 fpm, with a maximum altitude capability of 31,000 feet. The Model F90 has the distinction of being the first King Air equipped with Beech’s advanced, multi-bus electrical system that featured automatic load shedding, five separate buses and solid-state current sensors for ground fault protection and bus isolation.
1976 – The U.S. Navy awards a contract to Beech for what is eventually 61 Model H90 King Airs for advanced, multi-engine pilot trainers designated T-44A.
1979 – The U.S. Navy purchases nine Model A200C designated UC-12B for use as personnel and utility transports for both the Navy and Marine Corps. Basically off-the-shelf airplanes, all were equipped with the 52-inch by 52-inch upwardopening cargo door of the commercial model 200C. Twenty-seven additional airplanes were ordered in 1980, another 22 in 1981, and eight in 1982.
1981 – The improved C90-1 enters production. Equipped with PT6A-21 engines rated at 550 shp for takeoff and 538 shp for cruise climb and cruise segments of flight, the C90-1 carried 384 gallons of useable fuel and featured a maximum takeoff weight of 9,650 pounds. Pressurization was increased to 5.0 psid providing a cabin altitude of 6,000 feet at 20,000 feet and 12,000 feet cabin altitude at 30,000 feet. Up to 350 lbs. of baggage or remote avionics equipment could be placed in the nose compartment with another 350 lbs. of baggage in the aft cabin section, depending on exact arrangement of cabin seats and options installed. Maximum cruising speed was 273 mph with a range of 1,497 statute miles.
1981 – Beech introduces the Model B200. Equipped with PT6A-42 engines that retained a rating of 850 shp but incorporated improved hot section components that enabled better climb and high altitude performance, cruise speed increased to 312 mph, pressurization differential increased to 6.5 psid and zero fuel weights was 11,000 lbs. A double-wide cockpit pedestal made flight deck entry-egress easier and many minor improvements were made to the interior.
Dec. 7, 1982 – First flight of the Model F90-1 King Air, which features pitot-type engine cowl design that improves air intake characteristics, particularly at high altitude. It was the first King Air to incorporate a multi-bus electrical system, and has an enhanced pressurization system that provides a sea-level cabin to higher than 11,000 feet. P&W PT6A-135A turboprop powerplants replaced PT6A-135 engines of the F90m but were still rated at 750 shp. Wingspan: 45 feet, 10 inches. Deliveries of the F90 began in mid-1979 and continued through 1983, when the F90-1 was introduced. A total of 236 aircraft (203 F90s and 33 F90-1s) were built, and 137 remain on the FAA registry.
