The Boeing 717 is an American five-abreast single-aisle airliner produced by Boeing Commercial Airplanes. The twin-engine airliner was developed for the 100-seat market and originally marketed by McDonnell Douglas in the early 1990s as the MD-95 until the company merged with Boeing in August 1997. It was a shortened derivative of McDonnell Douglas’ successful airliner, the MD-80, and part of the company’s broader DC-9 family. Capable of seating up to 134 passengers, the 717 has a design range of 2,060 nautical miles [nmi] (3,820 km; 2,370 mi). It is powered by two Rolls-Royce BR715 turbofan engines mounted at the rear of the fuselage.

The first order for the airliner was placed with McDonnell Douglas in October 1995 by ValuJet Airlines (later AirTran Airways). With the 1997 merger taking place prior to production, the airliner entered service in 1999 as the Boeing 717. Production of the type ceased in May 2006 after 155 were delivered. As of June 2022, 103 Boeing 717 airliners remain in service and have recorded zero fatalities and no hull losses.
