King Air C 90 GTi

Beech Model 90 King Air is a light multi-purpose aircraft developed by the American company Beech Aircraft. At 1963, Beech began to conduct flight tests of the aircraft, which was subsequently designated BeechQueenAir Model6580. It was considered as a continuation of the type of aircraft QueenAir and developed for the US Army as a transport or general use aircraft. Its designation was confusing, as 80 and 65 QueenAir aircraft were still produced. Therefore, the aircraft was temporarily designated Model 6590T (the letter T means "turboprop"). Then another step was taken to clarify this situation, and all the QueenAir series aircraft that have a turboprop engine were renamed KingAir.

As a result, the 6590T aircraft became the prototype for the Beech Model 90 King Air series, more precisely, the prototype of the military unpressurized King Air aircraft. After the first flight of the model 6590T designed a civilian version, having a sealed cabin. Its production model under the designation Model90 King Air 20.01.1964 soared for the first time.

These aircraft marked the beginning of the three-thousand-series King Air. The tests of the 6590T model, conducted by the US Army (where it had the designation NU8F), demonstrated full compliance with all necessary requirements. As a result, the first order for 48 aircraft under the designation U21A was followed. The plane could accommodate a crew of two people and 10 military personnel, or 6-8 man command staff, or 3 stretcher. The chairs were easily removed and a place appeared for the location of the cargo mass up to 1361kg. The first deliveries of U21A Ute serial aircraft started 16.05.1967. As a result, contracts were followed and more than 160 machines were built. These include the U21A models, RU21A / RU21D models with turbo-screw motors Pratt & WhitneyCanadaPT6A20 shaft power 550l.s. And models RU21B / RU21C / RU21E with motors PT6A29, shaft power 620 hp

RU21 plane was specially designed for use in Southeast Asia, as an electronic intelligence. He had a set of antennas and sensors on the fuselage, and inside - appropriate systems and avionics and navigation systems that provide all-weather operation. RU21B and RU21C had from the company designation Beech Model65A902 and Model65A903 respectively, and assigned the designation U21G 17 aircraft, which were intended for the US Air Force, and were similar to the planes U21A.

Deliveries civilian version 90KingAir, which had a pressurized cabin, and up to ten seats, including pilot, started at the end of 1964. In the early 1966 the aircraft supplanted model KingAirA90, on which was mounted a more powerful motors RT6A20. One of these aircraft was used by the military code VC6A.

Following the A90 model was the King Air B 90 aircraft, which had minor improvements, and in September the 1970 was the King Air C 90 aircraft, on which more advanced cabin heating and air conditioning systems were installed. The С90 was in mass production during 1982, approximately 1000 of such machines were manufactured. One of them, under the coding VC6B, was also in service with the US Air Force. From its appearance, the С90 aircraft was constantly improving, the PT6A21 motors were mounted on it.
