I was on an AA flight last week from LAX that returned to the airport after 30 minutes due to smoke alarms and a stink in the cabin. The plane was taken out of service and we were assigned a new aircraft which took off a few hours later to finish the trip.

Is it easy to find out the exact reasons why the aircraft was taken out of service? I'm rather curious why they let us on the aircraft in the first place, because after we boarded the initial flight the captain told us there were problems but he would try it and see how things went.

It would be easier if we knew what day and what flight. But AA "last week" may be specific enough for some intrepid trackers of such things...  Wink

It depends on who you have access to. Anyone with the AA maintenance organization could find out very quickly. The OEM and engine maker would also know, although they won't share that with anyone other than the FAA and AA. A member of the public, without additional resources, can't find out too much.

They may have had a deferable defect that they thought they could work with. Or they may have had a fault from the prior leg that was cleared but maintenance wasn't sure that they solved it and told the flight crew to watch for it. Regardless, you don't take the airplane out of service unless you know you have a problem that you can't dispatch with.

Hard to say for sure based on your info, but when I hear "stink" in the cabin the first thing that pops into my mind is a bird strike (or strikes), and in the engine core section (versus the fan section. There may have been some bent blades such they needed replacement before further flight.

Too me. "stink" means a PACK has gone bad. In-flight smoke warnings are a different story. It is possible something overheated in the E&E compartment, set off the warning and the smell. Or a malfunction in the smoke detection system occured and suddenly the crew "smelled" something.

Do you smell the "stink"?

What type aircraft?

OK. AA flight 285 April 17, 2008.

YES! We smelled the stink. It was awful and smelled of cleaning fluid or perhaps hydraulic fluid. The captain said "I know it doesn't smell spring fresh back there, but we're told that once the engines start the air conditioning should improve the smell and, if it doesn't, we will not use this aircraft." Well, the stink remained after engine start and long after take off. 30 minutes later, we returned to LAX and the plane was taken out of service.

There were repeat write-ups concerning "a smell" but all reports indicated the smell dissipates with use of A/C packs. Maintenance checked the plane at LAX prior to your flight with the same results. Plane WAS scheduled to be routed to TUL two days later for a more comprehensive inspection, but your flight changed that plan. Captain reported the smell dissipated significantly after engine start & A/C packs turned on. That condition changed upon level-off when the crew turned off the right recirculating fan in an attempt to "eliminate any residual smell." Shortly thereafter the F/A's called complaining of "an electrical smell" and when the FO went back to check that out, the Smoke Alarm in the aft lav area began activating. That's what prompted the immediate return to LAX. The FO returned to the cockpit to say the "smoke" was dissipating (right recirc fan back on), but the decision to return was already made.

Acft was grounded for two days while LAX maintenance searched for potential sources. Plane was ferried to TUL for additional troubleshooting. Maint. found a small oil leak from the APU, but are still not satisfied... at least that's the last info I found.

AAR90, thank you so much for that information. Were you able to access that information easily? Do civilians typically have access to that much information?

No Big grin

When I worked for my carrier, I use to be able to go on the company intranet and pull up logs under ship numbers and it would say where they aircraft flew for the day, where it was scheduled to fly, who flew (CAPT/FO) and what delays they had and why. If it was MX related, there was usually a short write up on what the issue was but nothing detailed.

Interesting info none-the-less.



What gets measured gets done.

Yes and no. Physically easy, but sourced from many different AA databases...took a bit of time.

Uh... no, I don't think so.

This shows the power of a.net! Amazing the network of people who can find answers and share their knowlegde. Interesting. Thanks for the post.
