McDonnell Douglas MD-90
1993 airliner series by McDonnell Douglas

The McDonnell Douglas (later Boeing) MD-90 is a retired American five-abreast single-aisle airliner developed by McDonnell Douglas from the earlier MD-80. The airliner was produced by the developer company until 1997 and then by Boeing Commercial Airplanes. It was a stretched derivative of the MD-80 and thus part of the DC-9 family.
After the more fuel-efficient IAE V2500 high-bypass turbofan was selected, Delta Air Lines became the launch customer on November 14, 1989.
The MD-90 first flew on February 22, 1993, and the first delivery was in February 1995 to Delta.
The MD-90 competed with the Airbus A320ceo family and the Boeing 737 Next Generation.
Its 5 ft (1.4 m) longer fuselage seats 153 passengers in a mixed configuration over up to 2,455 nautical miles [nmi] (4,547 km; 2,825 mi), making it the largest member of the DC-9 family. It kept the MD-88's electronic flight instrument system (EFIS).
The shrunken derivative of MD-80 or shorter variant of MD-90, originally marketed as MD-95, was later renamed the Boeing 717 following McDonnell Douglas' merger with Boeing in 1997.
Production ended in 2000 after 116 deliveries.
This brief starts where responsible research should: with the source description of “McDonnell Douglas MD-90” as 1993 airliner series by McDonnell Douglas. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as 1993 airliner series by McDonnell Douglas. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Aug 14, 2026. The linked authority identifier is Q862615. The Library of Congress control number is sh99014339. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1997, 1989, 1993 and 1995.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
