The DC-8 Super 60 airliners are stretched developments of the DC-8 Series 50 re-engined with CFM56 high bypass turbofans. The DC-8-61 differed from the earlier DC-8-50 in having two fuselage plugs which increased length by 36'8in(11.18m), increasing max seating capacity to 259 and underfloor freight capacity by 80%. Intended for domestic operations, its max takeoff weight was identical to the DC-8-50. The Super 62 was intended for long range operations and featured only a modest 6'8in (2.04m) stretch compared to the Series 50, greater wing span, revised engine nacelles and pylons and significantly increased fuel capacity. The Super 63 meanwhile combined the DC-8-61's fuselage with the DC-8-62's wings.
McDonnell Douglas initiated a reengining program of Super 60 series aircraft with CFM International CFM56 engines in the early 1980s, known as the Super 70 Series. The first converted airframe flew in August 1981. The Super 70 aircraft are considerably quieter than their predecessors, with better fuel economy and greater range.
It should be mentioned that a considerable amount of DC-8 Super series have reached over 100.000 flight hours. Only very few aircraft have achieved this. |
