737 Cargo Bin Question

Mon Dec 03, 2012 5:48 am

Hello All:

The other night I worked A/C 270 ( ex Ford 737 ) and noticed that on many of the ex airTran and other second hand 737's we operate, there is some sort of "bar" in the side walls of the bins. I haven't noticed this on any 737's that were delivered directly to WN. My question(s) is what is the function of this bar, and why doesn't SWA opt to have this on its 737's.

FWD Bin A/C 270 ( 737-705 )

FWD Bin A/C 240 ( 737-7H4 )

Does it have holes in it for cargo heat?

Its a cover for the fwd galley/lav grey water drain tube that ends at the fwd drain mast. Grey water drains through the tube whether its airborne or on the ground. On the aircraft without, the grey water drain tube is above the cargo compartment ceiling. Due to the lack of slope, the grey water doesn't drain through the fwd drain maston the ground. Instead there is a drain valve that opens when on the ground that diverts the grey water to the door sill drain and exits the plane just aft of the NLG wheel well.

I don't know the reasons behind one design or the other, though I personally like the idea of not having the drain/cover in the pit. Mainly due to always having to re-bend the cover retaining clips and sealing the cover with tape. At AS we have only one NG with the drain line in the ceiling, N549AS.

Isn't it located midway of the Cargo compt & not the lowermost location......

Not exactly sure what you mean. The cover/tube runs the entire length of the fwd pit, sloping from about three quarters the height of the pit at the front to just above floor level at the back.

Because it continues forward of the pit at a constant slope to the lav/galley.

Whatever it may be it makes a good ledge to sit on while I am in the bin waiting for more bags to be sent up!

Its a good seat, but it makes it hard for you to slouch down and take a nap while waiting on the bags!
