The design effort focused on the Series 55 in August 1977. Availability of newer versions of the Pratt & Whitney JT8D turbofan engine with higher bypass ratios and thrust ratings drove early studies including designs known as Series 55, Series 50 (refanned Super Stretch), and Series 60. In the 1970s, Douglas began development of a lengthened version of the DC-9-50, with a higher maximum take-off weight (MTOW), larger wing, new main landing gear, and higher fuel capacity.
