The McDonnell Douglas DC-10 is an American wide-body airliner manufactured by McDonnell Douglas. The DC-10 was intended to succeed the DC-8 for long range flights. It first flew on August 29, 1970; and was introduced on August 5, 1971 by American Airlines.
The trijet has two turbofans on underwing pylons and a third one at the base of the vertical stabilizer. The twin aisle layout has a typical seating for 270 in two classes. The initial DC-10-10 had a 3,500 nmi (6,500 km) range for transcontinental flights, the -15 had more powerful engines for hot and high airports. The -30 and -40 models had higher weights supported by a third main landing gear leg for an intercontinental range of up to 5,200 nmi (9,600 km). Based on the -30, The KC-10 Extender is a U.S. Air Force tanker.
A design flaw in the cargo doors caused a poor safety record in early operations. Following the American Airlines Flight 191 crash (the deadliest US aviation accident), the FAA grounded all U.S. DC-10s in June 1979. In August 1983, McDonnell Douglas announced that production would end due to a lack of orders, as it had a widespread public apprehension after the 1979 crash and a poor fuel economy reputation. Design flaws were rectified and fleet hours increased, for a safety record later comparable to similar era passenger jets.
Production ended in 1989, with 386 delivered to airlines along with 60 KC-10 tanker aircraft. The DC-10 outsold the similar Lockheed L-1011 TriStar. It was succeeded by the lengthened, heavier McDonnell Douglas MD-11. After merging with McDonnell Douglas in 1997, Boeing upgraded many in-service DC-10s as the MD-10 with a glass cockpit to eliminate the flight engineer position. In February 2014, the DC-10 made its last commercial passenger flight. Cargo airlines continue to operate it as a freighter, its largest operator is FedEx Express. The Orbis Flying Eye Hospital is a DC-10 adapted for eye surgery. Some DC-10s are on display, while other retired aircraft are in storage.
The DC-10 is a low-wing cantilever monoplane, powered by three turbofan engines. Two engines are mounted on pylons that attach to the bottom of the wings, while the third engine is encased in a protective banjo-shaped structure that is mounted on the top of the rear fuselage. The vertical stabilizer with its two-segment rudder, is mounted on top of the tail engine banjo.
The horizontal stabilizer with its four-segment elevator is attached to the sides of the rear fuselage in the conventional manner. The airliner has a retractable tricycle landing gear. To enable higher gross weights, the later -30 and -40 series have an additional two-wheel main landing gear, which retracts into the center of the fuselage. It was designed for medium to long-range flights that can accommodate 250 to 380 passengers, and is operated by a cockpit flight crew of three. The fuselage has underfloor storage for cargo and baggage. More details
