wow, quite a nervewracking experince, but glad they were ok. Was the load really 187? thats like only one open seat? or are they just assuming because it holds 187 people there actually WAS that many people?

Wow, after this and the "famous people" AA 757 "terrifying incident with cut engines" last week (see other thread), AA's 757s must be horribly maintained.
I think it's time to replace those ancient birds with brand new A321s. I mean, come on, what is any self respecting Legacy Carrier doing flying something built in the early nineties with late seventies technology?
(COUGH, BARF, et cetera)

Anyhow, does anybody know what can lead to smoke entering the cabin? I am in aero-science school, and can't think of HOW that could even happen. Let's see... Compressor bleed air is taken off the engine. No chance for smoke there, unless you're flying over a forest fire, or unless the engine is shooting flames BACKWARDS through the front. Unlikely. Let's see... 757/767 cabin pressurization and climate control schematic... here goes:
Then it is ducted into the wing center section. No flames there.
Then it is sent through intercooler 1 and cooled. No flames there.
Then is it sent through the compressor turbine. No flames there.
Then it is sent through intercooler 2. No flames there.
Then it is sent through the discharge turbine. No flames there.
Then it is sent through the water separator. Surely no flames there.
Then to the mix manifold. No flames there.
Then trim air is added. No flames there.
Then it is ducted to the cabin. No flames there.
Then it shoots out of gasper fans and other ducts to my pointy little nose, which picks up evidence of... FLAMES??? Whatever!

But really, smoke in the cabin is something that seems to happen at least once a week. So WHERE THE HECK DOES ALL THIS SMOKE COME FROM???

Maybe this should go tech-ops... whaddya think?

I had a Ford Thunderbird several years ago and while driving on LBJ freeway in Dallas I smelled smoke. Moments later there was smoke billowing out of the center console (from under the power window and power mirror switches). Some frayed wiring I think. I never did find out what started it because I sold the car about two weeks later.

Needless to say, maybe the smoke got into the cockpit because it started there.....?

Decing fluid finding it's way in to the air conditioning ducting running across the ACM (air cycle machine) across the heat exchanger into the cabin...there you go.

Question:

We all know that media reports of any "emergency" are usually way off and very exagerated but the linked article suggests that it took them 50 minutes to get the plane on the ground after the smell of smoke was first detected... I sure hope this is an example of creative reporting because if that is accurate then AA's SOPs didn't change much after SR111. Any comments?

Horribly Maintained? Are you serious?

Ancient? Are you serious? oldest one 1989 and the youngest 2002?

The 757 is one of the most efficient a/c in AA's fleet.

What routing would they take to go FLL to LAX? I would assume the depature out of FLL would take them up to the LAL VOR and then they went to orlando? If it was 20 minutes into the flight they would have smelled the smoke just south of Avon Park, so continuing into MCO was the logical choice.

That has to be the most stupidest reply I have seen on here yet. I suggest you look at the safety record of the 757 and reconsider. When you fly a large amount of any fleet type you are bound to run into a problem every now and then, it happens. Hell I guess NW is dancing with the devil with their DC-9's based on technology from the 60's. And it has been stated on here the oldest 757 in AA's fleet is 17, with the youngest being only 3 years old acquired from TW. The only airbuses you will ever see in AA colors is the A300-600R.

AAFLT1871 and B752fanatic,

Something tells me he is being sarcastic.

Kudos to the flight crew and flight attendants for getting the plane down safe. Seriously, if I had to pick an airline to have an emergency on, God forbid, American would be right at the top of my list.

If it indeed took 50 minutes to get the plane on the ground from the time of the smoke being smelled/seen, I am sure that time could be attributed to dumping fuel for a safe landing. If you land an overloaded airplane, you could end up with more problems then what you started with.

AA's 757s hold 188 pax, this particular flight had only one open seat. Add to that the bags and hefty fuel load for a five hour west bound flight and you've got a heavy bird. Landing it only twenty minutes after taking off without dumping fuel could have serious consequences.

I won't even stick up for myself. Except to say, did you not read all of my post? This is what happens when you jump to conclusions, you make a fool of yourself.
"(COUGH, BARF, et cetera)"
THAT was your indication of sarcasm.

The 757 is one of my favorites, I am flying two Continental examples this summer, Houston to Anchorage. You think I don't trust them? I trust them for seven hours straight!

Viking air- could you please explain that further? I don't see how deicing fluid could get into a CLOSED air system. But clearly you've got some info I don't know about... I'll shoot you an email.

Anyone know the tail #?

Reason I ask is that I was on an AA 757 (AA 2160) last Monday that landed in SJU enroute SXM-MIA with smoke. 5EF.

Wondering if it was a repeat...

First the article said there was smoke in the cockpit. Nothing about originating from the air conditioning. It could have been electrical in nature. Second, had it been from the air conditioning there are possibilities. 1. bearing failure(burning)2. pack overheat. On one checklist for a particular GE engine it refers the crew to a possible fuel/oil problem and check for an increase in oil qty. The checklist is "Smoke and Fumes from Electrical, Air conditioning OR Unknown Origin" All of these conditions call for an immediate landing. Our checklist says not to stay aloft in order to run the checklist.

Could the smoke have come from the packs at all? That would be the most logical guess I think.

AA737-823, with all due respect I'd rather fly on a 40 year old Boeing aircraft than a brand new Airbus. Furthermore, if AA "horribly maintained" any of its aircraft they would soon find themselves in very serious trouble with the FAA. I doubt seriously if any of AA's, or any other USA carrier's aircraft, are "horribly maintained". This is not a third world country, we don't put planes in the air that are put together with paper clips and a prayer.

I'm glad nobody was hurt.

Just curious if this was an ex-TWA bird (PW engines) or an AA bird (RR engines). Not that it matter really, but I'm just curious is all.

I was jumpseating EWR-CLT in an ExpressJet ERJ. After takeoff, the PNF was configuring the engine bleeds to open and the APU bleed closed. When he opened the #1 engine bleed smoke billowed into the cockpit (and cabin I imagine as the flight attendant said there was some). It smelled oily and was really thick and almost had a greasy feel to it. Possibly oil leaked from the bleed air check valve (9th stage) or from somewhere in the engine and burned in the pack (it gets damn hot in there!)
