737 Airstair?

Fri Jun 29, 2001 10:50 pm

Hey Everyone....
I know this probably belongs in the Tech/Ops column, but I never have much luck there. Anyway, here is the question. In my Jet Transport Systems text (which focuses on the 737-300/500), it talks about the Air-Stair system. I know the -100 and -200 had the stairs, but I didn't think the later models were equipped. Can anyone tell me if the -300/400/500 as well as the -600/700/800/900 include a stanard equipped airstair, or is it just an option? Do the NGs even have this as an option. Thanks gang.

I somehow envision 737 3/4/500 of some African airline with a built in stair. Air Malawi maybe? Anyway, I´m pretty sure I´ve seen auch a photo; I´ll see whether I find it.

I remember that Turkish Airlines had 737 with the staircase. When I looked at some of the pictures of THY 737 on .net I saw the staircase "cover" under the front left door on -400 and -500. There is nothing like that seen on -800.
Considering that many airlines don't have them on their 737 -300 -400 -500 and NG and can not be a standard equipment.

You know, I was going to make a very similar post myself! What got me started was the Southwest Airlines 30th anniversary feature in the July issue of Airways (?). The picture with the flight attendants in miniskirts and hotpants looks to be taken on integral airstairs (yeah I know it's sad that I noticed the stairs that hot panted ladies were standing on), while the photo on the opposite page of the newly delivered 73G does not seem to have the hatch for them. Oddly, in the same issue, there is a pictorial about 4 717s delivered on the same day to TWA. These DO seem to have them. I guess they were eliminated to save weight, but I am unsure if they are still optional.

The 737-100 series had a built-in airstair at the 2L door. The door would drop down, unfold the stairs, and handrails would come up and you could board or deplane easily. This was removed on the 737-200 to save weight (it was a very heavy piece of machinery) and replaced by the integral stairs at the 1L. I believe these are options on all 737s, but most airports have the equipment to handle 737s and do not require an integral airstair.

Deutsche BA 737-300s have them, HHI 73Gs have them as well as OAL 717s.

The airstair is an optional extra offered by the manufacturer. I have flown 737-200/300/400/500/700. Some had them others did not. Now this is for the front door. There are very few airlines that opted for the rear door airstair. I have only seen this once in the US. Never in Europe. Some 737-300 I flew did not even have the airstair controls or the door in the fuselage installed. Others simply had the airstair removed post delivery.

I remember reading somewhere that the -200 was the last 737 with the airstair.

ALL 737s have an Airstair option, ive checked 4 different sources on this.

Most of the Combi 737-200 retain the fold down door on 2L. I can think of one exception to that rule though.

I have also seen a -300 737 with the forward airstair.

A recent issue of Flugrevue (sorry, forgot which one) had a cutaway of a 737 NG. It clearly showed an airstair.
