Re: MDD DC-9 'Air Stair' (Rear Passenger Ramp) Location
« Reply #25 on: October 23, 2020, 08:04:45 AM »
Can anyone share a drawing or URL that shows where the rear passenger door/ramp is located on the MDD DC-9?  My recent acquisition of the Aurora 1:72nd scale DC-9 kit has minimal details and most every image or drawing I have found so far on-line pretty much ignore this unique feature of the DC-9.   

I would like to try and scribe in the detail of the ramp on the underside of the fuselage if possible.

Found these, Jeff. Don't know if you already have them;

Drat!

Maybe not the clearest images but it has a bit of good info in it:

You might, also, want to get the forward airstairs right, too.

Thanks for the assist Guy!  The first image you linked to appears to have created a hot-link conflict and will not show. 
The other images are in view. 
The "Air Stair" feature for the forward access door is not featured on the old Aurora kit, just the outline of the door and according to my research efforts it was not fitted to all DC-9 aircraft.  The rear steps are what I am after.  The rear view does help some in establishing the width of the thing and I can do some more guesstimation on where it lies on the underside of the fuselage. 

Without getting in to too much detail.  The objective is to try and scribe in the rear access stairs or if possible create an open step feature for an "alphabet agency" clandestine cargo aircraft that could drop "stuff" at night or in adverse weather.  Based on something I read several years ago that I think was a B727 that had the rear stairs modified to create a ramp to allow delivery of small "door bundles" with parachutes in support of some guerilla war.  So with that in mind, I hope to create something similar from the DC-9.  It has no windows along the fuselage sides so it is almost ideal for a cargo carrier.

Seeing that rear stair reminded me of something, when I went to the Yeovilton Royal Navy Museum, they had one of the prototype Concordes on display and you could do a walk through the cabin. We accessed it through a rear stair ---- but exited through a side cabin door near the front.

Evidently most DC-9-10 don't have the ventral stairs and the old Aurora kit is more
or less a DC-9-10. Stairs were optional on later series. Non-stair aircraft have a
detachable tailcone and an escape chute. The built in fwd. airstair was fitted to all
but the freighters.

Page 33 of this airport planning doc shows the critical clearances for the ventral stairs.
The door measurements are 27.75" X 72". Page 28 shows the Fwd. Cargo Door on the
freighter versions, pg. 19 has the interior arrangement for a 'shorty' freighter, the Aurora
kit is a shorty DC-9.

@JCF - Thanks for the additional information.  I must have missed the bit on the ventral stairs not being on all versions.  The kit states it is a model of a DC-9-10 and that was about it.  I still like my idea of a clandestine cargo delivery aircraft with a ventral stair converted to a ramp with rollers to facilitate smooth delivery of cargo bundles in the dark of night.  :smiley:

Otherwise, it goes to the scrap heap...

I'll buy it off you Jeff, if you come to that

Do you know that DC-9 could be a downscaled DC-8 with 4 smaller engines? https://www.secretprojects.co.uk/threads/douglas-dc-9-development-concepts.9880/
