      A very interesting feature of early 737 (-100srs. and some -200)
      was the downward pivoting L2 door with integrated airstairs.
      Very unique and never appeared on newer versions!
      The airstairs were removed later for weight reasons - unfortunately.
      Flew an ALOHA -200 some years ago which had yet those airstairs.

      How could the L2 door opened from outside?
      I couldn't find a door handle on any pics.
      Was there an operating panel
      anywhere on the fuselage as on DC-9's / MD-80's?

      Anyone any ideas?
      I'm sure Great-J would know but unfortunately
      he's offended and angry with me because
      I didn't agree with him and had a different view.
      Contradicted him! I'm sorry!

      I'm not "great" but Sven, you just don't know when to stop.

      Here's what I can offer on the technical topic. This is an Air California safety card from the late 70's. They had a couple of aircraft in their fleet with this feature.

      Unfortunately, this does not show the exterior access, however there would need to be one for operational and rescue purposes. There is a handle below and just forward of the L2 door with a placard stenciled on the side of the fuselage. I think it might be safe to assume that this would be the door control, since none of the 737s I have flown have this. BTW, the C-40 has a rear airstair as well, but uses an underfloor arrangement different than this design. Hope that helps...

      Cheers,

      Dan

      Several 737-200 combis operated in Alaska (by Wien and Alaska Airlines) were fitted with the fold-down L2 door and airstair. Look at this photo of N740AS and you can just barely see the red placard and door control low on the aft fuselage, at the white/gray border below the L2 door. (Ahmed, forgive me if I'm not linking this correctly).

      In 1924 Wien was Alaska's first airline. In 1980 it still is.

      Boeing says "It can be extended or retracted electrically from either inside or outside the airplane. Manual extension can be accomplished from either inside or outside; however, manual retraction is provided from the inside only." Must have been quite a load to retract manually!

      This shows the handle in some detail. My friend Petr took this while working for CSA.

      Hello Jodie, Dan & TWA Brat,

      thanks for your responses!
      It was very interesting to read and helped me very much!
      The outer operational handle is clear to see on the pics.
      Too bad that the fold down airstairs disappeared....
      Dan, you said the C-40 has a rear underfloor arrangement?
      Hard to believe the airstairs fits under it...but must be anyhow.

      thanks again
      Sven

      Some company has built a similar fold-up rear airstair for a Boeing 757: http://www.airteamimages.com/boeing-757_N757AG_avcon-jet_244174.html

      Hello all,

      The C-40 does indeed have a rear air stair but I was mistaken about it being an underfloor unit. I found this photo showing one being deployed. It is not attached to the door itself but appears to stow in the galley area in some fashion. Here's a link to the photo....

      The C-40 promo video on this page shows the rear air stair operation a bit better...

      The following shows a forward stair being stored under the floor in a classic 737 of Air New Zealand:
      https://www.youtube.com/watch?v=goP9EhL4v94
      Starting from 2:45 mins.
      So this is an alternative (later) arrangement?

      Best regards,
      Pieter

      Hi Pieter,

      As far as I know, the optional forward airstair arrangement has always been very similar, if not indentical to the Air New Zealand 737s in the video. The big difference is the rear airstair option on the -100 and -200 aircraft versus the newer setup available on the military C-40 which is not connected to the actual L2 door itself. BTW, thanks for the video, which is quite good and shows the later hushkits that were also used by airlines like Lufthansa to get the old JT8Ds to meet the increasingly strict noise requirements.

      Cheers,

      Dan
