What Is This Door On A CR9?

Fri Jul 05, 2013 6:26 am

I was plane spotting at CLT the other day and noticed a mini door a US Airways Express CRJ 900; in the picture below it is just before the engine (over 7F of the registration) and you have to zoom in fairly close to see the outline of the door.


Can anyone tell what the door is, does and where it is located in the cabin?

Thanks,

According to various safety cards and the Seatguru seating chart, it is not an emergency exit. In any case it would have to be a contrasting color for that.

Could it be a service door that is not an emergency exit? Seems weird since as far as I can tell there are seats on the other side.

Now that I've been unhelpful, I'll make way for someone who has a clue.  Smile

Its got the metal scuff plate on the lower frame, so a functional door.

There was a thread about this several years ago, but in that thread it was a service door for an optional rear galley. The first few CRJ-900's had the door frame in the airframe structure. If there was no galley, the hole was plugged.

No operator has ordered a CRJ-900 with a rear galley, so the door frame has been removed and the rear galley is no longer an option.

As to where it is in the cabin, behind the "door" is probably row 20 in the map above.

You'll have to search the tech ops forums for the original thread about this door.

   It was my thread, and it's here: YV CR9s- Extra "Door?" (by Cubsrule Nov 20 2010 in Tech Ops)

There's not much more information there, though. I think you've covered it.

This seems to be making the most sense.....Any reason why the rear galley was not needed.

Empty galley space doesn't generate any revenue?

I don't know.

I guess a corporate operator could have had a rear galley installed. I don't know if there are any corporate CR9s. I've seen a few corporate CR7s, and the CR700/900/1000 maintenance manuals have documentation for the installation and removal of a rear galley and wardrobe closet.

The door does not look like it is a good location. Seems like a tight fit for a catering van between the wing and engine and violates the safety diamond of RJs.

I'm guessing no CR9 operator provides a level of catering that cannot be met with just the forward galley.

It's not as close as it looks. There are special catering vehicles used for RJs that are much more narrow than a standard "small" catering truck. You'll see a bunch in Atlanta.

As far as the safety diamond thing, I'm not sure what you mean by that specifically There are certain GSE equipment that are exempt like belt loaders, GPUs, air carts, catering vehicles..
What gets measured gets done.

I have seen those trucks before and they work better then what other stations do for catering RJs. i.e vans, pickup trucks, and golf carts.

The diamond is a invisible line from the nose to wings to the tail of the aircraft where motor driven GSE can not enter, the coning is at the nose and tail and hurdle cones at the wings (DL thing)

Carriers have cut back in-flight service in Y class so much there's no need for it. That's even more true for RJ operators.

That's an odd concept;
How do they load baggage? By hand?
How do they service lavs? By bucket?
How do they fuel the plane? By long hose?
How do they cater? By hand cart?

The idea of not allowing GSE near airplanes virtually eliminates the purpose of GSE......
But, then, most safety departments exist only to prevent us from doing our jobs, so it's a believable rule.

A GECAS specification for the then-new CRJ900 in 1999 describes an 80-seat aircraft with a double galley both front and back, loads of carts and containers and three ovens(!). The good old days when inflight catering was more substantial  

The double galley at the back removes four revenue-generating seats, which is a lot for a 80-90-seater and not really a realistic option in today's environment.

However, Lufthansa CityLine, Eurowings, Adria, Estonian and SAS have a galley at the back of their CR9s, an aisle-facing galley unit with three half carts, two ATLAS containers and a coffee maker. Garuda also has this galley unit in their CRJ1000, so there are still some airlines that offer something to nibble on even on a regional jet.

Read my post more clearly, I am talking about motor driven GSE (Tugs,Vans,Fuel Trucks, etc.)

Quoting AA737-823 (Reply 12):

The belt loader is the only piece that is allowed in the diamond but it cant make any contact with the plane

Quoting AA737-823 (Reply 12):

With a push cart

Quoting AA737-823 (Reply 12):

The fuel truck sits outside the diamond and the hose from the truck will reach the fueling panel

Depends on the station, ATL has catering trucks for RJs. DTW and PHX have vans and pickup trucks and yes they service the galley by hand through the catering door.

What are you talking about? I assume you have not worked any regional jets. Regional jet ramp handling is different from mainline aircraft handling.

We let all sorts of motorized equipment (baggage tugs, powered lav service truck, fuel trucks, motorized catering vehicles, etc) all within the safety perimeter of our CRJ's. Guess it's just an ASA thing.
