COMMERCIAL AIRCRAFT first time. The aircraft is due to be completed by the end of this year, with the first flight due in early 1998. The first delivery to Valujet will fol- low'in June 1999. With Boeing's management examining the future of the MDC commercial products, there has been some speculation that the MD-95 could escape the axe, and be developed as part of Boeing's niche 100-seat airliner programme, slotting in below- the 737. A short-fuselage 80- seat MD-95-20, as well as a stretched model, have been talked about in the past. Production Final assembly will be undertaken at the Long Beach plant. Ordered 50 Delivered 0 MD-11 A stretched, re-engined derivative of the DC- 10, the MD-11 had its first flight in January 1990, and Finnair introduced the type into rev enue service in December the same year. Although the programme gained several significant customers early on, in recent years sales have been slow. The 295-seater initially failed to meet its original performance targets, forcing MDC to introduce aerodynamic and structural changes. The latest MD-11ER ver sion exceeds the original specification, being able to carry its specification payload of 2 98 pas sengers more than 13,340km. MDC has developed a freighter version, which FedEx introduced in May 1991, and an after-market cargo conversion is offered. Combi and convertible passenger/freighter versions have also been delivered. The MD-11 could continue under the Boeing regime if the new owners decide that it can survive in the long term in its niche role as a cargo aircraft. Production MD-11 final assembly takes place in Long Beach, with 15 aircraft being delivered during 1996. Production is now running at around one aircraft a month. Ordered 183 Delivered 166 EMEBS Company no longer exists Cammacorp was set up in 1979 to oversee the CFMI CFM56 retrofit programme for the MDC DC-8 Series 60, but the company no longer exists. Other partners in the programme were MDC, CFMI, and Grumman Aerospace, the latter being responsible for the manufacture of the engine pods, cowlings and pylons. Between 1981 and 1986, 110 aircraft were retrofitted, with the modified aircraft dubbed the Series 70 (the variants were designated DC- 8-71, -72, and -73). Most are now freighters. The CFM56-2C5 engines provided the -70 with fuel-consumption improvements of up to 23%. Take-off, climb, cruise-altitude and range performance were also significantly improved. See McDonnell Douglas entry for details.
