I saw this pic today and it is identified as a DC-8-71. I thought that DC-8-63's were renamed in the '70 series with the new engines. This looks more like it belongs to the DC-8-50 series. Any ideas?

Its a DC-8-72. The DC-8-62 was not as long as the -61/-63 series. Relatively few of these aircraft were re-engined.

Yep, that's a -72, and a good-looking specimen at that! N102DA is correct, very few were re-engined. I bet that plane is a rocket...

Zeb, just so you'll know...

All -70 series DC-8's have the CFM56-2 engines obviously. But here is an easy way to tell the difference.

A-71 has the stretch fuselage.

A -72 doesn't have the longer fuselage, but has a longer wingspan than the -71.

A -73 has the longer fuselage AND the longer wingspan.

Regards.

Ummm I am very fimiliar with that aircraft, in fact I was the Lead/Supervisor and C-Checked that aircraft at Dee Howard in San Antonio. We then painted it with the livery you see before you. It has two APU's and under floor long range tanks and an awesome interior. I didn't like the plane because we had to wear those stupid booties when you worked on it but by far the best looking and maintained DC-8, I have ever seen! You can't really notice it in this picture but that tail design is 3D, when you look at the design it has an optical illusion and appears to stick out. ARAMCO spares no expense on the aircraft and it even has a MECCA indicator.

The main distinguishing feature between 61/71 and 63/73 series DC-8's are the engine pylons. On 61/71's, the pylon protrudes through the wing leading edge, on the 63/73 (and 62/72) it doesn't.

Trident....

You're going to have to show proof to support your statment.

I can't see what you're describing.

Sorry - no facilities or knowledge to post pictures. In the shot of the 72 above you can see that the pylons are connected to the bottom of the wing only and no part of the pylon is visible from above the wing. On 61/71's, the pylons appear to be "inserted" into the wings and part of the pylon appears above the wing's top surface - a bit like on all Boeing 707's.

Hope that helps. I noticed the difference when building Revell's 1/144 scale DC-8 Srs 10 and DC-8 Srs 63. The 61/71 used the original style pylons design for the first DC-8 (Srs 10/20//40/50). The Series 62/72 and 63/73 used a new more aerodynamically efficient pylon design.

Trident, I'm sorry, but I feel the need of correcting the info about the 61/71 pylons; the -61 indeed looks the way you've described (and so does the -50 series), but the pylons of ALL series -70 aircraft looks the same!!

...here, I show you what I mean...

Looks like McDD took the oportunity to modify the pylons on the 71 when converting them to carry the new engines.

No, they didn't!

The series -70 conversions were made by CammaCorp.

New engines (CFM-56), and new pylons.

If you look closely, it's visible that the series -70 pylons differs from all other models of the DC-8, they had to hold them up higher, because otherwise the engines would come too close to the ground (and increase the possibility of a podstrike in bad weather conditions).

71 series pylons are the same as 72/73 series pylons.
