Extra Door On 737-900

Hi all, I just returned from a trip on which I flew United, on a 737-900, and my question is, there is an extra door, after the over wing exits, but before the rear exit door. From the inside, it does not show, any means how to operate that door, nor is there an example on the safey card, does this door really exist?
as I was walking down the aisle to my seat, there was an Exit sign showing but no diagrams on how to open that door.
thanks for any help on this matter

CO specified the extra doors aft of the wings on the 739ER to be replaced by non-openable plugs, since the extra doors are unnecessary in the two-class configuration that they operate them in. Replacing the doors with non-openable plugs saves weight.

Yes on the 737-900ER they have an extra exit behind the wing, but on the united aircraft its blocked off due to the amount of seats on the aircraft, then it wouldnt require the extra exit. United aircraft has about 173 seat on the ER if I remember correctly which is less than the required limit of 189, with the extra exits the capacity of the 900ER increases to 215 seats.

You flew on a 737-900ER not a 900. The extra door is in fact a plug on United 900ER's. The purpose of the doors are to allow for more seats in a single class seating arrangement, with two class seating the extra doors are unnecessary. A simple way to differentiate between the two is a small circular window is in a door while a plug will have a standard window.

I hope there was not an exit sign, since the door is a plug and is covered by a sidewall panel. There should not be an exit sign pointing to a non serviceable exit.

The rear emergency exits on KE and TK -900ERs are also deactivated as they have fewer than the 190 limit where doors are needed, although in KE's case only 2 seats less (8J/180Y). According to their website seat map, TK has a very spacious layout on their -900ERs, 16J/135Y, total 151. That's even fewer seats than on any of their -800s which have 4 different configurations with a total of 155/165/177/189 seats per their website.

If the exits were activated they would have a painted outline around them like the overwing exits.

exactly what I was thinking....looks like if the door was deactivated its important that the Exit sign was removed too.

Newer Boeings often have exit signs in the aisle with no exits nearby.

I think around 20 or so of our B737-800 aircraft have an EXIT sign 3/4 down the cabin, between the overwing exits and aft doors - never understood why. On newer aircraft that exit sign is gone.



Come, fly the prevailing winds with me

The concerned company should get it corrected,if the door is INOP,the Sign should NOT be there.
