A Southwest Airlines Boeing 737-8 MAX, registration N8792Q performing flight WN-3923 from Havana (Cuba) to Fort Lauderdale,FL (USA), was climbing out of Havana's runway 06 when the right hand engine (LEAP) emitted three loud bangs and streaks of flames, an engine fire indication occurred, smoke developed in the cabin. The aircraft returned to Havana for a safe landing, vacated the runway and stopped on the taxiway. The aircraft was evacuated via the left hand slides, emergency services sprayed the right hand engine.

The aircraft is still on the ground in Havana about 15 hours after landing back.

The airline reported the aircraft suffered bird strikes to nose and engine. The aircraft was evacuated due to the smoke in the cabin.

@DXR. Yes, had commented on the embargo issue in earlier post. That’s why I’d like to hear the story. Between tools, parts and insurance issues, have advised clients to only fly to Havan(n)a if it’s on someone else’s aircraft.

Looks like they are having trouble getting this particular aircraft back in-service. After a few days additional delay at HOU. It appears the A/C flew to SJC late morning today - and promptly cancelled the rest of its schedule, and tomorrow.

Embargos make it more difficult to import parts/engines to repair a plane. It literally takes a waiver from the State Department to ship the parts.


another typo
By The typo enby on Thursday, Mar 30th 2023 18:19Z

There's an equals sign in "O=n" (first word of 4th paragraph).


Typo in title
By The typo enby on Thursday, Mar 30th 2023 18:12Z

Havana is incorrectly spelled as "Havanna" in the title.


Departure
By USJETS on Sunday, Mar 26th 2023 19:35Z

Aircraft departed Havana yesterday after 20 days AOG. Scheduled to return to service Tuesday. Love to hear the story and why it took so long.

Anonymous - It’s still on the ground in Havana - Anyone got an update?

Wonder how getting parts into Cuba is going to go with the embargo still (eyeroll) in place.


O2 Mask Deployment
By Proteus on Tuesday, Mar 7th 2023 22:30Z

Drop-out O2 masks deploy automatically when the cabin altitude reaches 14000 ft. They can also be manually deployed from the flight deck. I can understand pax getting agitated due to painful, stinging eyes and ingestion of oil fumes, particularly if Skydrol hydraulic fluid was involved. However, the cabin looked pretty calm in the videos available elsewhere. Not a good experience. Smoke Hoods with built in O2 are available for cabin crew, but I have not seen any evidence that they were used.


@Byron: birds need oxygen too
By J on Tuesday, Mar 7th 2023 03:59Z

Great points but unlikely they were that high. Bird strikes usually aren’t.

Some media reports have pax pounding and jamming the overhead panels to get the masks in a panic, not understanding how they work. That might explain why only one set of three is visible in that picture.


O2 mask deployment
By Byron on Tuesday, Mar 7th 2023 02:06Z

Part of the smoke clearing procedure for the cabin opens the outflow valve to encrease air flow through the cabin, if they did this at high enough of an altitude with one of the bleed air sources turned off then the cabin pressure would drop resulting in the masks deploying.


O2 masks
By Juan José Pérez Egert on Tuesday, Mar 7th 2023 00:59Z

Justo to clarify some missknowledge , passengers oxigen is provided trough an individual o2 generators , that gas is ihaled mixed with the cabina air (with smoke if pressent) diferent is the case of the pilots "full face" O2 masks that ones can be usted as smoke removal. There is not another use nor procedure than deploy the Pax masks in a decompresion situación.


O2 masks
By Juan José Pérez Egert on Tuesday, Mar 7th 2023 00:45Z

Why they deployed the oxigen masks? They system should be usted only at high altitudes , oxigen and smoke is a dangerous combination.


@Kelle

Where do you suggest they get the wet towels from in that moment?


@Strebav8or
By Kalle on Monday, Mar 6th 2023 22:40Z

My answer is C:

I want them to understand that the masks do *not* provide clean oxygen and use wet towels instead.

Those masks are only for decompression.


Why the Engine Fire Indication?
By Jetman on Monday, Mar 6th 2023 20:33Z

Obviously Hi temp detected in the nacelle....
Engine Failure associated with warning, may trend to beleive that an engine case contained failure with broken HPSOV air duct as a potential scenario.....Which in this case having the pack off be useless.
Fuel/smell in cabin due to engine surge do not necessarily trigger fire warning but looking at above event, engine failure was severe with morelikely correlated damages...









Questions
By Proteus on Monday, Mar 6th 2023 17:31Z

Why the Engine Fire Indication? Possible uncontained failure of the affected engine?
Why were RH evacuation slides deployed? The fire crews appeared to be attacking a fire on that side.
Why were O2 masks available to just three pax? No real benefit would result anyway. As already noted, the masks supply a mixture of O2 and cabin air.

It will be interesting to follow the repair and return to service of this Aircraft. Between US Export restrictions on Cuba, and restrictions on payments to Cuban Government-controlled entities, it may take some extra time to overcome administrative/bureaucratic hurdles as well as obtain appropriate licenses. Not sure SWA can “sneak” in the necessary parts and tools - as on-board spares - on today’s flight.


@Juan José Pérez Egert - O2 Masks
By Strebav8or on Monday, Mar 6th 2023 16:50Z

If your loved one was on this flight, would you:

A. Want them to be choking on the smoke, or
B. Want them breathing clean oxygen?

And, in the fire triangle it is:

Oxygen
Heat
Fuel

Smoke is not part of the triangle.

The masks in the cabin deliver a mix of oxygen and cabin air. Means if you take a deep breath you will inhale alot of smoke, too.
Using a wet cloth is way better than those masks. They are there for decompression, not for smoke in the cabin.


@ Juan José Pérez Egert
By J on Monday, Mar 6th 2023 16:40Z

Oxygen and *fire* is a dangerous combination. When you have thick smoke, and the fire is clearly outside, oxygen can save your life.


Re: O2 Masks
By (anonymous) on Monday, Mar 6th 2023 16:04Z

"Why they oxígeno masks? They system should be usted only at high altitudes , oxigen and smoke is a dangerous combination."

The source of the smoke was obvious. Would you have preferred them suffocate the passengers?

MUHA Bird Acticvity
By Strebav8or on Monday, Mar 6th 2023 15:49Z

I can speak with some good knowledge the MUHA - Havana is notorious for frquest bird activity and strikes.


@Jody
By BobLoblaw on Monday, Mar 6th 2023 15:34Z

I wondered the same thing about the masks — that’s a definitive “NO” at my company…


Designation
By Observer on Monday, Mar 6th 2023 15:18Z

When the passengers read the original designation and get worried by it, it's anyhow too late as they are sitting ready for take off. If they ever read it! LOL


Mask
By Jody on Monday, Mar 6th 2023 14:58Z

How come this person has access to cabin oxy mask. I thought it was a no no.


@anon
By Charlie Victor on Monday, Mar 6th 2023 13:05Z

Ref the -8200, you may want to acquaint yourself with the FAA or EASA TCDS for the Boeing 737.


@anon
By igi on Monday, Mar 6th 2023 12:28Z

Again, no. The 8200 designation has been used by Boeing as far back as 2016. Ryanair has nothing to do with it.
Yes, it is still the Max 8. But in standard one class configuration, this variant seats 200 people (210 maximum) as opposed to the regular variant with 189.
That is where the 200 part comes from. Not Ryanair.



By Greg on Monday, Mar 6th 2023 12:28Z

Jesus already explained this to you. -8200 is max 8 with high density cabin configuration- it is different from regular max because it has additional mid doors in between over wings and aft doors.

With an engine fire indication you'd do the engine fire memory items. However you'd start the procedure at or above 400ft, which can take some time if the problem occured around the time the aircraft lifted off.
And even then, it doesn't take 4 seconds to get to the 4th item, that'd be 1 item per second. Yes, a fire is serious, but important is not to rush. Fly the airplane first, and do the procedure when the
400ft: HDG SEL, Bank 15, Identify: Takes a few seconds.
Then the call for memory items, followed by: A/T disengage, thr lever close (with confirmation), engine start lever cutoff (with confirmation), fire switch pull (with confirmation).
Takes about 30-40s until the fire switch is pulled, plus the time to reach 400ft.
