View Full Version : Hawaiian Air A321 Smoke in Cabin Emergency

A Hawaiian Airlines jetliner made an emergency landing in Honolulu on Thursday after smoke filled the cabin and cargo hold, and seven people were taken to hospital, officials said, according to Reuters.

Obviously a lot of details to come out, but one wonders what would have happened had this started several hours out of HNL instead of only 20 minutes.

Pics clearly show grey ish mist and the company stated it came from the engine due to a faulty seal. You know breathing this crappy air is full of toxins like organic phosphates etc.

So many incidents like this are happening, did happen and will happen, clearly getting more media coverage now. The verdict about the Aerotoxic syndrome is not out yet but regulatory agencies all over the world are doing larger scale investigations into this due to the higher public pressure. The word is finally getting out and many lawsuits are ongoing. Several airline unions have accepted the possibility of the Aerotoxic Syndrome and have implemented measures like adapting smoke/fumes checklists, more education and the request to ALWAYS report a fume/smoke event and testing of cabin air.
I was skeptical but have changed my mind after studying this for a long time. It is clear that cabin air is frequently contaminated with invisible toxins from high temp oil burns and crews and pax are exposed to it often for a long time.
As all pilots know, the bleed air from the engine is NOT filtered in any way, duh. It is PROVEN that the jet engine seals to keep lubricant oils in the core do leak frequently as they are kept in place by air pressure differential. So many of you pilots know the dirty sock smell when larger power changes happen, like throttles going back to idle at descent. That smell is most of the time not bad smelling air from condensation blankets but some of the neuro toxins.
A lot of effort is now underway, worldwide to prove or disprove any relationship between exposure, long term low dosages and sudden high dosages as in a smoke event and the effect on the human body.
I now strongly believe that crew is often exposed to longterm low dosage toxic cabin air and it causing health issues, often longterm.

Many crew unions have come together to form the Global Cabin Air Quality Executive (GCAQE (http://gcaqe.org/)), a not-for-profit organisation specifically set up to help resolve this issue. The largest conference (The Aircraft Cabin Air Conference (http://aircraftcabinair.com/)) ever held on the issues raised in the film takes place in London on 17-18 September.

A documentary on this issue will be released to the public in London in September, .everybodyflies.com/ (https://www.everybodyflies.com/)

I am not a conspiracy theorist and am pretty level headed, this is something real that we as crew members need to take serious. Just for once think about the air you are breathing for hours and hours in that tube........and start the conversation with your colleagues. It is your health, the industry has been aware of this for over 40 years and have kept it quite, the least you can do is to give it a serious thought and wonder why EASA, CAA, union etc etc are starting to address this...

Enjoy your flying and stay healthy( good beer is healthy too :))

So what are the ways to remove smoke from the cabin? Luckily they were only 20 minutes out from a Honolulu, but suppose they had been 1-2 hours away from the nearest suitable?

​​​​​​Suppose the crew corr correctly diognoses the problem as being smoke from one of the packs. The Airbus initial procedures from smoke and fumes calls for the switching off of Cabin Fans. Once the smoke source is detected and isolated would one be tempted to switch the fans back on to try and get the fumes out faster? I know that large portion of the cabin air is recirculated, but eventually it would be replenished. With the Cabin Fans off is there any way to get the smoke out?

Would love to have a Bus driver chime in, but my understanding is that if the crew knew what the problem was, they could turn off the bleed air from the affected engine. But the initial diagnosis was a fire in the cargo hold, and fire suppression measures for the hold were employed....

The switching OFF of the CAB FANS is merely to prevent smoke from entering the cockpit and cabin. Prior to that, the VENTILATION BLOWER and EXTRACT are selected to OVRD to extract avionics ventilation air overboard. AIR COND smoke will quickly trigger SMOKE warnings such as lavatory, cargo and avionics, nevertheless those ECAM procedures must be applied.

If AIR COND smoke is suspected the APU is switched OFF (if ON) and VENTILATION BLOWER and EXTRACT returned to AUTO (prevents depressurisation, single PACK operation may not maintain cabin pressure). Then PACK 1 is switched OFF. After 5 minutes, if smoke continues PACK 1 is switched ON and PACK 2 is switched OFF. After 5 minutes, if smoke continues PACK 2 is switched ON and VENTILATION BLOWER and EXTRACT are switched to OVRD.

REMOVAL OF SMOKE/FUMES is a follow-on procedure and depends on whether or not fuel vapours are present. Basically, if NO fuel vapours: CAB FANS OFF, PACK FLOW HI, set LDG ELEV to 10,000’ or MEA-MORA, DESCEND. At 10,000’ or MEA-MORA, if smoke on cockpit: reduce speed to 200kts, open PM sliding window to clear CKPT smoke.

And ultimately you can go into the smoke removal checklist whenever needed.

Basically descend to FL100/MEA. Get the packs off, set landing elev to current FL, open outflow valve fully and get the Ram Air on. Fresh air enters the cabin through the Ram and out through the outflow.
