The Boeing 717 is a twin - engine narrow -body aircraft produced by the American aircraft manufacturer Boeing . The short- and medium- haul aircraft made its maiden flight on September 2, 1998. In May 2006, Boeing stopped manufacturing the 717 due to a lack of new orders.
history
The ideas for the Boeing 717 go back to 1995, when McDonnell Douglas was planning to build a renewed version of the MD-90 based on the Douglas DC-9 under the type designation MD-95 . After the takeover of McDonnell Douglas by Boeing in 1997, the project was continued under the name Boeing 717, so that on September 2, 1998, flight testing of the 717-200, which was designed for around 100 passengers, could begin. The 717-200 was approved for the first time in 1999 by the Federal Aviation Administration (FAA) and the European Joint Aviation Authorities (JAA). A shortened 717-100 and an extended 717-300 never got beyond the concept phase. The BMW Rolls-Royce AeroEngines BR715 serves as the engine .
The first of a total of 156 Boeing 717s was delivered to AirTran Airways in autumn 1999 . Final assembly of the aircraft was carried out at the former McDonnell Douglas plant in Long Beach , California . Boeing announced on January 14, 2005 that it would cease production of the 717 in 2006 due to lack of demand. The last two machines were delivered to Midwest Airlines and AirTran Airways on May 23, 2006 .
There have been no incidents with a Boeing 717 that resulted in total loss or casualties.
Versions
Note: Boeing internally named the KC-135 Stratotanker military tanker aircraft with the model number 717.
Boeing 717-100X
The Boeing 717-100X or McDonnell Douglas MD-95-10 was a planned variant of the 717. It should be designed for an average of 86 passengers, which was to be achieved by shortening the fuselage by 1.93 m in front of and behind the wing . As with the Airbus A318 , it would have been necessary to raise the vertical stabilizer because of the change in leverage . Since such a variant would have had relatively poor direct operating costs and would have competed with several aircraft, Boeing stopped following these plans from the beginning of December 2003.
Boeing 717-200

The Boeing 717-200 or McDonnell Douglas MD-95-30 is the only built variant of the 717. It is designed for an average of 100 passengers. Boeing also offered a "HGW" version ( H igh G ross W eight) with increased take-off mass and thus increased range. However, this version could not be sold once.
The concept of the Boeing 717 was still presented as MD-95 at the Paris Airshow in June 1991; the schedule provided for a program start towards the end of the year; the first flight was scheduled for July 1994. However, a first customer was a long time coming; It wasn't until October 1995 that ValuJet ordered 50 MD-95s and signed options for 50 more. After the takeover by Boeing, this aircraft manufacturer continued to pursue the concept and finally launched it as the Boeing 717-200 in January 1998. The first flight took place on September 2, 1998. The type was certified on September 1, 1999 and the first series aircraft was delivered to the first customer AirTran - the successor airline of ValuJet - on September 23 .
Boeing 717-300X
The Boeing 717-300X or McDonnell Douglas MD-95-50 was a planned variant of the 717-200. It should be designed for an average of 130 passengers, which would have been achieved by lengthening the fuselage, whereby the fuselage in front of the wings would have been increased by 2.41 m and behind the wings by 1.45 m. This aircraft was best known for the planned large orders of various airlines in the Star Alliance , where the 717-300 competed against the Airbus A318-100 , Bombardier CRJ900 and Embraer 190/195 . Ultimately, however, everyone decided against the extended version and thus the end of the 717-300 was sealed.

Of 155 units delivered, 148 are still in service as of April 2019:
| operator | Number (active) | Remarks |
|---|---|---|
 Delta Air Lines

91 (88) | 3 inactive |
 QantasLink
|
20th | operated by Cobham |
 Volotea

Hawaiian Airlines

| total | 148 (145) |
The seven already parked aircraft flew continuously for Turkmenistan Airlines until 2018 . The only remaining original operator is Hawaiian Airlines .
By far the largest number of 717-200s are used today by Delta Air Lines , which is also the world's last operator of the technically closely related MD-90. The machines were not procured from Boeing by Delta itself, but mainly came from two used sources: Trans World Airlines , which were taken over by American Airlines and later sold their 717s to AirTran , and AirTran itself, which (still as ValuJet ) were first-time customers. The latter were sold in 2010 by Southwest Airlines , which today lease the aircraft to Delta.
