Most airliners with tail mounted engines do. Goodness knows why, but my guess is its simply a good place to put them. They dont take up space in the actual cabin area. I immagine airliners with wing mounted engines dont use them because of the jet exaust that would wash over the passengers using them. Anyone know anything else...?

The only Boeing with AFT Airstairs (excluding 717's) is the 727, none of the others have them. A few of the 727-100's also had FWD stairs at the L1 door. I think some 737's have FWD stairs, but I'm not sure if they all do or it's an option.

The 737-100 had aft stairs at the aft left pax entry door. Actually the folding stairs had the door as an integral part of the stairs assemby. This was on People Express's 737-100's they purchased from Lufthansa. I'm not sure if was standard equipment on all -100's

The logic behind the built-in airstairs on the DC-9, 727, 737 classic was that many of the airports that these planes would be flying into, in the 1960's, simply didn't have the facilities to handle loading and off-loading passengers, not jet ways. And it is cheaper to have the airstaris on the plane than to drive the stair truck up. Of course nowadays you'd be hard pressed to find a commerical airport that didn't have some minimal ability to handle full-sized jets.
