The MD-83 is a mid-range passenger aircraft developed by McDonnell Douglas, an American company. McDonnell Douglas started developing the MD-83 aircraft in January 1983. It differs from the previous versions by its increased take-off weight and large fuel reserve, which required reinforcing the wing skin and fuselage, installing new landing gear supports, and reinforcing the longitudinal beams of the cabin floor.
The first aircraft began to undergo flight tests on December 17, 1984. The certification was completed in October 1985, and the first aircraft was delivered in November. Initially, aircraft were delivered with a take-off weight of 67.8 tons, and in November 1985, the version with a take-off weight of 72.6 tons was certified.
The aircraft is equipped with the usual avionics system with electromechanical data display facilities. In recent years, at the request of the customer, the digital complex EFIS can be installed. Installed 2 turbojet engines Pratt & Whitney JT8D-219 (thrust 9845 kgs). This modification has been produced since 1985. By the beginning of 1997, about 230 aircraft were built.
