DC-10-30 NORTHWEST MODEL

The McDonnell Douglas DC-10 is an American three-engine medium- to long-range widebody airliner, with two engines mounted on underwing pylons and a third engine at the base of the vertical stabilizer. The model was a successor to the companys DC-8 for long-range operations, and competed in the same markets as the Airbus A300, Boeing 747, and Lockheed L-1011 Tristar, which has a similar layout to the DC-10.

Production of the DC-10 ended in December 1988 with 386 delivered to airlines and 60 to the U.S. Air Force as air-to-air refueling tankers, designated the KC-10 Extender. The DC-10 was succeeded by the related McDonnell Douglas MD-11 which entered service in 1990.

DC-10-30 (164 built) was the most common model built with General Electric CF6-50 turbofan engines and larger fuel tanks to increase range and fuel efficiency, as well as a set of rear center landing gear to support the increased weight. It was the second long-range model after the -40 and very popular with European flag carriers. Produced from 1972 to 1988, the DC-10-30 was delivered to 38 different customers, amongst which Lufthansa (11), Swissair (11), VARIG (11), KLM (10) and Iberia (9) were the largest.
