![]() The shorter fuselage but longer range MD-87 is described separately under McDonnell Douglas. The specific MD-80 models are the initial MD-81, the MD-82 with more powerful JT8D-217s, the extended range MD-83 with extra fuel and more efficient JT8D-219s, and the MD-88 (first flight August 1987) with the JT8D-219s of the MD-83 with an EFIS flightdeck and redesigned cabin interior, with other improvements. The MD-80 designation however is a generic designation for the series and does not apply to a certain model type. McDonnell Douglas renamed the DC-9-80 the MD-80 in 1983. The first customer delivery was to Swissair in September 1980. Certification for the initial Super 80 model, the 81, was granted in July 1981. Launched in October 1977, the Super 80 first flew on October 18 1979. Instead MDC developed the DC-9 Super 80 (or DC-9-80), combining the new engines with a further stretched fuselage, increased span wing and other improvements. MDC originally proposed fitting the new engines (which meet Stage 3 noise limits) to a development designated the DC-9-55, which would have featured two JT8D-209s and a 3.86m (12ft 8in) stretched fuselage over the 50. The origins of the MD-80 lie in 1975 testing where a standard DC-9 was fitted with improved, more efficient, higher bypass ratio JT8D-200 series turbofans. The popular MD-80 series is a stretched and improved development of the McDonnell Douglas DC-9.
