737-MAX9 Door Plug Questions

Thu Aug 15, 2019 6:56 am

Hello All:

As we all know the 737-900ER/ 737-9MAX has the option for the extra door or door plug with larger window. If an airline does not need that additional exit, why does it have a door plug instead of just the regular window layout (what the 737-900has). Also, is it possible to remove the window door plug and convert it to an additional exit?

It is cheaper to manufacture the fuselage in only one configuration and then plug the door when required. When plugged, the interior trim hides the door plug edges, but it is visible on the outside.

I believe it can be changed back into an operating door at an additional expense. This also enhances the resale value as it gives a more flexible option for future owners who may need the door.

The same applies to the A321neo with the new layout, where the second over-wing exit is plugged unless required.

An exception to this is the 777-9 where it appears if you select the 4-door option, they do not actually cut out the 5th door and plug it, but rather build it without the door at all.
