history

Main article: Development history from the Douglas DC-9 to the Boeing 717

The development of the third generation of the DC-9 started in November 1988, the first flight of the only version, the MD-90-30, took place on February 22, 1993. The MD-90 has a modern cockpit with EFIS screens and a flight management system . After a certification program, the aircraft type was approved on November 16, 1994, the first aircraft delivered on February 24, 1995 to Delta Air Lines , which ordered 31 copies.

After McDonnell Douglas was taken over by Boeing in 1997, Boeing announced in 1997 that it would cease production of the jet; the last of a total of 117 MD-90s built was delivered to Saudi Arabian Airlines on October 23, 2000 .

The MD-90 including the planned shortened and extended variants MD-90-10 and MD-90-50 fell victim to the takeover by Boeing , because the aircraft was only sold slowly and also competed with the company's own Boeing 737 . The reason for the difficult situation on the market was primarily the Airbus A320 family , with whose modern technology the MD-90 could not keep up. In addition, the A320 had a larger fuselage cross-section and thus, with the 3 + 3 seat configuration, offered better seating compared to the 2 + 3 variant of the MD-90. Boeing only took over the already well advanced development towards an MD-95 reduced to 100 seats and launched it as the Boeing 717 .

Only two of the originally planned 40 MD-90-30T were produced in Shanghai and delivered to China Northern Airlines . Some components from this license production were then taken over for the later developed ARJ21 .

Incidents

• On August 24, 1999, a passenger died in an explosion aboard a Uni Air MD-90-30 ( B-17912 ) while landing at Hualien Airport . The explosion was presumably caused by flammable liquids being carried in hand luggage (see also Uni-Air flight 873 ) .

• On March 9, 2009, a Lion Air MD-90-30 came off the side of the runway when landing at Jakarta Airport , with the main landing gear buckling and the machine touching down with the underside of the fuselage. The 172 people on board survived the incident unscathed, but the aircraft had to be written off as a total loss.
