Douglas DC-9The McDonnell Douglas DC-9 (initially known as the Douglas DC-9) is a twin-engine, single-aisle jet airliner. It was first manufactured in 1965 with its first flight later that year. The DC-9 was designed for frequent, short flights. The final DC-9 was delivered in October 1982.
The DC-9 was followed in subsequent modified forms by the MD-80, MD-90 and Boeing 717. As of May 23, 2006, with the final two deliveries of the 717, production of the DC-9 aircraft family has ceased after 41 years.
Design and developmentDouglas launched the DC-9 development project in April 1963, intending the DC-9 as a short-range companion to their larger four engined DC-8.[1] Unlike the competing but slightly larger Boeing 727, which used as many 707 components as possible, the DC-9 was an all-new design. The DC-9 features two rear fuselage-mounted Pratt & Whitney JT8D turbofan engines, small, highly efficient wings, and a T-tail. In most configurations, DC-9 aircraft have distinctive 5-abreast seating in coach class. The airplane seats 80 to 135 passengers depending on version and seating arrangement.
The DC-9 prototype first flew in February 1965. The second DC-9 flew a few weeks later and entered service with Delta Air Lines in late 1965. The initial -10 variant would be followed by subsequent growth variants. The final DC-9 variant was the -50, which first flew in 1974. The DC-9 would be a commercial success with 976 built when the production ended in 1982.
The DC-9 would be followed by the introduction of the MD-80 series in 1980. The MD-80 series was originally called DC-9-80 series and was a lengthened DC-9-50 with a higher maximum take-off weight (MTOW) and higher fuel capacity. The MD-80 series was then developed into the MD-90 in the early 1990s. The last variant of the family was the MD-95, which was renamed the Boeing 717-200 after McDonnell Douglas's merger with Boeing in 1997 and before aircraft deliveries began.
The DC-9 is one of the longest-lasting aircraft in operation. Northwest Airlines still operates a fleet of DC-9 aircraft, most of which are over 30 years old. The DC-9's reputation for reliability and efficiency drove strong sales well into the 2000s. 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 3,000 produced, and the first place Boeing 737 with over 5,000 produced
