AA 777-300ER, Minus Vertical Stab?

Fri Nov 30, 2012 2:46 am

What is the reason behind this? I have never heard of or seen pictures of a plane being on the flight line in such an unfinished condition like this ( and the 787 doesn't count).

I'm assuming that there had to be some sort of issue with the vertical. Does anyone know if it was found prior to or after assembly?

Seriously though, I have to agree, this is not a common sight.

might be for the special livery. That means the body might just be a solid color and the vertical have the slick design

Agreed. There was article out this morning from local Dallas news station confirming new livery but saying that AA refuses to say when or how it will be revealed. My guess is they planned on doing it already but w/ the pilot contract out for vote they want to make double sure the labor issues have settled down first, i.e. last thing they need is to unveil new livery/logo/77W roll out along w/ commercials and such w/ backdrop of another major slowdown and media circus.

I think it has more to do with the delay in 77W deliveries, although I see you point about avoiding a labor showdown after the "birth of the new American", or however they spin it.

So they went and wasted a massive amount of money painting a 77W white and grey just to entertain ANetters?

I join the ones who say that it is strange that the vertical stabilizer is taken off completely on the flight line. Even if they wanted to keep the new tail logo a secret, it shouldn't have been necessary to take the vertical stabilizer completely off like this.

In the mean time we are all awaiting the new livery AA will be introducing

This strikes me as being a quite drastic move just to hide the new logo, why not leave it on and paint it all white instead.
After all, the rest of the aircraft still has teo be painted.
So what's happening to AA 77W's on the FAL in production now ? Presumably the third one is there or thereabouts by now. Is it being built without the vertical stab ?

Isn't 717AN still out on the flight line with no logo on her vertical stabilizer?

Plus 718AN hasn't even had her fuselage painted, so why would Boeing slap the logo on her tail? And even if they had for some reason, easy enough to cover it up in the paint hangar before they rolled it out.

The only way this makes sense to me as a logo-related issue is if they're painting the vertical stabilizer separately, but if that was the case you think they would have pulled it off of 717AN, as well.

So I'm guessing there was an issue with the tail that requires fixing. Maybe they banged it into something and damaged it?

How did they remove the tail? Did they do it outside, or move it into the factory and use a crane? I thought that balance of the tail is so critical that manufacturers must handle it very carefully. Yanking it off outside doesn't seem to fall within the handling protocol if that is the case.

They would have had to use a crane, whether it was inside or outside. Given that the factory has overhead cranes everywhere, it would seem very likely that this was done inside.

Quoting JAAlbert (Reply 18):

That's true, although it's really only the rudder that has a major balance concern.

Quoting JAAlbert (Reply 18):

Even if done outside, nobody is "yanking" anything. If you ding it, you've got to repair it regardless of the balance. So you don't ding it.

Agreed. Traditionally, when an airline is introducing a new design that is not ready for reveal, they "tape" white sheets over the design to hide the painted artwork. We saw this with many carriers including JetBlue, a couple years back now when they introduced the blueberry tail design and new upsized logo.

The removal or non-attachment of the the vertical stab. is too extreme of a move to be related to the new livery in my opinion. There are much less dramatic, and cheaper, options to hiding the colours.

Actually it is none of the speculation listed above. This aircraft is testing a new 777X feature which does not have a vertical stabilizer (saving a ton of weight) but instead uses fly-by-wire controlled split ailerons and differential computer controlled thrust asymmetry to achieve directional control resulting in significant fuel savings. If thrust control plus split-ailerons doesn't result in satisfactory yaw control, they will also use a control vane in the APU exhaust to supplement the authority.

Vertical fins, are hinged and are folded to one side before they are removed. This can be done outside or inside with the use of cranes.

As Stitch said, there probably was some damage as this is usually the only reason you ever remove a vertical fin. The Rudder is the only thing that gets removed for new livery applications (most of the time), due to the need to "balance" it after the new paints are applied.

With AA 77W production delayed, this vertical stabilizer was probably swapped to another aircraft in final assembly.

I believe they stopped doing that with the 707.. originally it was to allow the plane into low clearance hangers.

As I recall all vertical fins are installed vertically and attached with pins laterally not fore and aft.

I seem to recall that the paint delay is due to a seat problem so no new paint until mid January.

I think the delay which is due to "seat issues" is smoke and mirrors. I think Q1 2013 you will see AA emerge from bankruptcy with a completely new rebranding top to bottom. You will not see the new branding until the day they emerge however. Carefully timed with the delivery of the 777-300. They aren't ready yet to emerge so they aren't ready to paint the 77W. It would be hard to keep that secret once it's completely painted. I think this white you're seeing on the gray plane is also a mule much the way they disguise new cars before they are released. In the end the tail will not be white but perhaps all blue. Just my

I never said that was better. Although in those cases yes they do look better than shiny tacky metal. Look at TG or EY and their liveries, no-one is saying you either have to have euro-white or tacky metal. AA's looks horrible. Look at AM if you want to see polished metal done correctly.

Waiting for a polished metal stab perhaps? Can't remove paint if the new logos are on AA polished metal background. Possibly getting a new stab that is polished with only the logo painted.

The 777 vertical stabilizer is CFRP, not Al, so it can't be polished.

718AN flew on 16 November with an unpainted vertical stabilizer (I can't tell if the rudder is white or grey in the ambient light).

Having spent a lot of time on AA, as well as sitting at ORD, I love the look of the 772 in the bare metal finish.

Considering the number of planes that are all white or mostly white, including UA, US, and DL, the bare metal finish can't be mistaken, especially on a sunny day.

If you think AA's bare metal is ghastly, what do think of the old Hughes Air West scheme, bright yellow with purple trim. That was ghastly, especially if they hadn't been washed for some time.

The vertical stabilizer on the KC-135 can be folded down, but it's a major production to do it so there has to be a good reason for it, IE serious maintenance, damage, or..... dropping a wrench down the stabilizer while changing a rudder compensator, perhaps....... .. not that I'd know about that, of course.....

I don't believe a word of this. No airplane can fly without a vertical stabilizer. It's a matter of simple physics. Every airplane from the Wright Flyer all the way to the present has had some form of a vertical stabilizer.

The B-2 Stealth doesn't have a vertical stabilizer, like etoile said.

But, with all due respect to Navion, I think that he was just kidding in what he was saying. Of course this 777 won't fly like that. As other have said, it was taken away by cranes to fix an issue, before continuing building the airplane. I think that the reason the airplane is not kept inside the hangar in Paine Field is not to block the production line.

Yes, Navion was trying to be funny. The nuances of humor can be difficult to convey through the printed word.

Speaking of aircraft with no vertical tail, check this out..

For curiosity sake and somewhat unrelated;

Was the X31 ever actually flown without the vertical stabilizer? It appears the photo above is an edited photo. I thought the X31 performed "quasi tailless flight test," utilizing intentionally destabilizing control inputs in roll and yaw and then controlled the destabilizing inputs via three dimensional thrust vectoring.
