The MD-80 series was introduced into commercial service on October 10, 1980.
The MD-83 (DC-9-83) is a longer range version of the basic MD-81/82 with higher weights, more powerful engines, and increased fuel capacity.
The DC-9 family is one of the most successful jet airliners with a total of over 2,400 units produced; it ranks third behind the second-place Airbus A320 family with over 6,600 produced, and the first place Boeing 737 with over 8,600 produced.
Compared to earlier models, the MD-83 is equipped with slightly more powerful 21,000 lbf (93 kN) thrust Pratt and Whitney JT8D-219s as standard.
The MD-83 features increased fuel capacity as standard (to 6,970 US gal (26,400 L)), which is carried in two 565 US gal (2,140 L) auxiliary tanks located fore and aft of the center section. The aircraft also has higher operating weights, with MTOW increased to 160,000 lb (73,000 kg) and MLW to 139,500 lb (63,300 kg). Typical range for the MD-83 with 155 passengers is around 2,504 nautical miles (4,637 km). To cope with the higher operating weights, the MD-83 incorporates strengthened landing gear including new wheels, tires, and brakes, changes to the wing skins, front spar web and elevator spar cap, and strengthened floor beams and panels to carry the auxiliary fuel tanks. From MD-80 line number 1194, an MD-81 delivered in September 1985, it is understood that all MD-80s have the same basic wing structure and in theory could be converted to MD-83 standard.
