Windows Missing On B737's

Wed Jan 26, 2005 3:37 am

This has probably been raised here before, but can anyone tell me why there is a window missing on 737's near to the engine intake/wing leading edge area on both sides:

On some of the larger models there are two windows missing:

Not good for passengers who like a window...

Thanks,

but good for passengers who like air conditioning. those windowless spaces are used for AC ducts and electrical wiring...
Some see lines, others see between the lines.

Could that area be for the mid-a/c toilet or gallary sections, especially on 757's and stretched version 737's?

Where were the air-conditioning ducts and electrical wiring located on the 737-200s? They don't have windows missing.

I've read that, based on analysis by Boeing, those are the spots on the fuselage that are most likely to be hit but flying debris, if there is an severe engine failure which causes chunks of cowling and fanblades in the forward section of the engine to start flying.

Having sat in a windowless seat on an AA 737-800, it makes sense, since seats farther back are over the wing, which would act as a shield during an engine failure.

No windows missing on Airbuses!

Ever heard of debris coming through the window?

Notice no blocked out windows on the 100's or 200's. One blocked on the 300, 2 on the 400 and 1 again on the 500 series. Seriously doubt that has anything to do with a catastrophic engine failure. If any part of that engine hits the wing, forget about it. That's a fuel tank there. I would like to know where they put the plug into the fuselage to lengthen it from the original models.

The blank framebays are for conditioned air riser ducts.

731 and early 732 have windows there because instead of using a few rectangular ducts they use a bunch of smaller round ducts that fit between the windows and the aircraft frames along the right side, aft of door 1 and forward of the wing. Later 732 have rectangular ducts and blanked window locations just like the modern ones.

i wonder if anyone ever called the cabin crew to say that a lump of debris landed on their lap whilst in flight??

ive never heard of that reason for having a window missing before, but I guess it may be valid. It is strange Airbus or other models dont have it too though if that is the case. I thought it was usually where the galley / toilets are located on larger models.

Yes,
The blanked windows at the wing leading-edge are for air conditioning riser ducts. Most Airbus types have them as well, in fact Airbus seem to have been the first, starting with the A300 in 1972...

And so on - only the smallest members of the family (A318/319/320) do not have the blanked window...

All 747 have them.
3 on each side.

All I know is that I was assigned that seat out of TPA last month and it sucks. Todd and Crosswind thanks for the good answers.

Are you sure? I've never seen a 732 with the missing window spots...

Those are where the AC Ducts are located.On the B738 it on Three places,the -700 Two places one either side.
On the B732,its passes from the Duct to riser ducts [narrow] from the RH Fwd side to the Ovhd Distribution duct.

TWA used to have a single DC9 that had a couple of windows missing on the port side with seats right next to them. IIRC, it was because the thing had been a combi and had had a cargo door there that was sealed up. It flew until pretty much the end. (I can't recall whether it was also the JATO DC9.)

Actually flew it once. Confused the heck out of the regular business passengers.

My understanding is that those areas are somehow reinforced to protect the a/c and pax from an engine failure (cowlings and fan blades). If you check pictures of the MD-8X series, there are also some windows missing right next to the engine intake. Please correct me if I am wrong.

The configuration shows up in the master IPC for 731 and 732 aircraft.
Unfortunately, I didn't note the effectivity.

Missing windows?!?!? Does that mean that there's a hole in the a/c??  Big grin
