Southwest Airlines plane makes emergency landing in Florida after engine breaks apart midflight
Source: New York Daily News
A Southwest Airlines jet bound for Orlando, Fla., was forced to make an emergency landing in Pensacola after one of its engines fell apart over the Gulf of Mexico.
Startled passengers on board Flight 3472 from New Orleans heard a frightening blast to the aircrafts left at an altitude of 30,700 feet. Outside their windows, they saw smoke fuming from the exposed turbine blades at around 9:20 a.m. Saturday.
All of a sudden, outside my window, there was a loud explosion, and then the plane started shuddering, passenger Tami Richards told KOCO-TV.
Chunks of the engine's cowling had fallen off, according to photos taken from the aircrafts window midflight. Another photo shows a metal object had pierced the fuselage.

(32,006 posts)It is like landing on a postage stamp with neighborhoods all around. You look out the window and you are just above traffic on the roads. Very unsafe airport in my view.

(36,827 posts)The northbound approaches into Dallas Love field take you directly over the tallest buildings in downtown Dallas. It looks hairy to the layman, but it's quite safe. The approaches are certified by the FAA for obstacle clearance with a wide margin or they couldn't be used in anything other than good visibility.

(32,006 posts)There have been at least four crashes at Midway casing deaths in the neighborhood.
In 1959 a TWA Lockheed Constellation crashed near 63rd Place and Kilpatrick Avenue (just a few short blocks from Tuesday's accident) killing eight people on the ground and the three occupants of the airliner.
1973 - A United 737 crashed on approach and impacted several houses killing two.
1976 - An Air Chicago Freight B-25 crashed on a training flight after an engine failure and subsequent fire. The airplane struck houses killing one woman. Two houses, two garages, three automobiles, and a boat were destroyed. One house was damaged substantially, while nine others were damaged slightly.
2005 - A Southwest airplane slid off an icy runway onto Central Avenue crushing a car and causing the death of a 6 year-old boy.
There have been many other crashes in the neighborhood causing injury but not necessarily fatalities.

(36,827 posts)So it sounds like that one crash alone did in more people than you found over a 45 year period. If you want to go back a hundred years or so to the WWI days I'm sure there there quite a few more.
Pretty much any airport in a highly urban environment is going to have fatalities both from inside the aircraft and outside throughout its history. That doesn't mean they are inherently unsafe. The roads surrounding them have far more fatalities just from ground vehicles.

(26,327 posts)Too late for that kid.
Yeah, it's certainly packed in pretty tight. I wonder how it stacks up, safety wise, with other urban airports.
My dad started there with American Airlines before the move to O'Hare.
I remember the B-25 crash in the neighborhood in 1976.. We drove by it some time shortly after the crash. I remember the freshly vacant lot where two homes used to be.

(7,768 posts)That's a GOOD thing! Pilots are required to train with simulated loss of engine and how to recover. (single engine airplanes obviously have a unique problem if the engine is lost)
Knowing all that, I would still be terrified seeing an engine on fire and exploding. Holy crap!

(33,144 posts)The second picture looks like it was something external to the jet engine that flew into the turbines. It looks like all of the compressor vanes are still there.
Totally weird.
I hope everyone has made it to their destination and glad nobody was injured.

Major Nikon
(36,827 posts)The reality is that bird strikes are exceedingly rare. I have well over 3,000 flight hours with exactly zero bird strikes despite flying at altitudes in which birds are the most common. Most of the real data we get about how high birds actually fly comes from bird strikes which are very rare occurrences. Each individual bird strike over 20,000' which is actually reported (many aren't), gives us new data, but the reality is we just don't know everything about where birds actually are because the data collection is so infrequent. Convective currents can propel birds to extremely high altitudes and they can be found pretty much everywhere the jet stream goes, including the Gulf of Mexico.
I'm not saying this is a bird strike and if I were to guess I'd say it isn't, but it certainly isn't outside the realm of possibility.

Major Nikon
(36,827 posts)Which lists no birds in North America over 21,000'. So by this we must conclude the numerous bird strikes reported in the US far higher than that must be mythological.

I held my kids, and one was freaking out, crying. And so, we're trying to hold his hand and singing and praying a lot," Richards said.
"I had my faith in god, so I knew that whatever was going to happen, he was with us," Richards said. "So I was able to stay calm. It wasn't until after I got on the ground that I got emotional."
Just always seems a bit misplaced to me.

(191 posts)If a mother is able to calm her children during a terrifying experience through her faith in God, more power to her. How does that diminish the courage and expertise of the pilots? Why should that matter to anyone?

(3,859 posts)I've been in the business for almost forty years and I've never seen or heard of an engine coming apart like this one.
The entire inlet cowl and low pressure turbine blade assembly is missing.
This investigation should be very interesting given the number of aircraft operating with this powerplant.

(2,993 posts)I don't fly SWA often (they don't serve my nearest airport), but I did before moving to my current location; their planes looked a little older than those flown by other airlines.
BlueCollar
(3,859 posts)From what little i know this engine recently went through scheduled maintenance.
If it was a full overhaul it would have been torn down to piece part, inspected, repaired/upgraded as required and reassembled.
My experience is mostly with Rolls Royce powerplants. This one is a General Electric but the principal is pretty consistent.
Lots of parts are retired/scrapped due to longevity during the overhaul process.
This looks like is massive failure of the low pressure turbine blade assembly...almost as if the shaft failed.
I am speculating of course. Normally in a situation like this you see a contained failure meaning the bits and pieces that fail remain contained within the cowl. Here everything departed the engine.
I must admit, the old Far Side cartoon of an airline passenger accidentally hitting the "wings stay on/wings fall off" switch on his armrest came to mind, but I've never seen one for "engine stays intact/engine comes apart."
The only concerns I've ever had as a passenger have been with older aircraft. I realize they're constantly and professionally maintained, so this isn't necessarily a rational worry, but it's a worry nonetheless.

(24,701 posts)That cone holding the fan compressor turbine blades and the inlet cowl are gone, and to have it done at over 30,000 feet tells me that they "could have had a compressor stall" caused by freezing on the inlet fan blades, and is not to be used as a way of represented as fact.
I also have been in the business for about thirty-five years
Hassin Bin Sober
(26,327 posts)Sometimes engines blow apart? No?
What makes this one so different? Is there something specific that makes this incident so unusual? I know uncontained failures are rare but they do happen?
Or am I missing something?
I know passengers have been killed by jet engines coming apart. My first thought was it was fortunate nothing penetrated the fuselage.
BlueCollar
(3,859 posts)Was traced to a fan blade disc failure that should have been caught during a routine fluorescent penetrant inspection.
It wasn't.
Your point?
My only observation was that this particular failure is very unusual. The. UAL failure didn't blow the front of the powerplants off and involved a fuselage mounted powerplants.
Hassin Bin Sober
(26,327 posts)There has even been penetrations of the fuselage resulting in passenger death.
It looks that almost happened here. One more reason, besides view, not to like the wing seat. Lol.
On the other hand, sitting near that emergency exit might come in hand when half the passengers are grabbing their luggage while the plane burns and the other half are twittering the fire.

(4,139 posts)Take a look at the images in this link:
http://www.kathrynsreport.com/2016/08/southwest-airlines-boeing-737-incident_27.html
These confirm the almost total departure of the front of the cowl and engine inlet from the nacelle, but the first stage low pressure compressor appears intact (I have seen unconfirmed reports of a single blade missing).
BlueCollar
(3,859 posts)My original post was based upon a photo that didn't clearly show the LP turbine blades.
In the latest pictures, it is clear that the LP turbine blades and
D spinner are still in place.
So it looks like the inlet cowl came apart. The inner lining appears to be in place...
Still damn strange...that's a lot of cowl to come apart...

(971 posts)I've been hearing for a while that a lot of the maintenance of aircraft has been outsourced as a cost saving measure. To countries in South America, South Asia, Africa; where the technician certifications and 'legitimate' parts availability is somewhat less than that in the U.S. and other countries.
Could this be a result of that?
turbinetree
(24,701 posts)And read this book----------------and just for giggles go back and look up Frank Lorenzo
The Betrayal of the American Dream by James Bartlett and Donald Steele
And finally let me say, this, I have worked at airlines that outsource there C and D checks, the requirements are that you only have to have "one" individual holding a FAA certificate with a PowerPlant and Airframe Rating and you can have a 100 people working on the aircraft that do not hold that certificate, the one individual that is holding the certificate, will sign off the "log book" saying the work being performed is done in accordance ( IAW) with the FAA and per the maintenance manual and the per manufacture procedures and is airworthy, the outsourced U.S. Flag Carriers work has to be done in accordance to the FAA procedures.
I want you to read Part 43.3 sub paragraph d, and after you read the entire 43.3 get back to me and tell me what you think, I will then tell you what I think
14 CFR 43.3 - Persons authorized to perform maintenance, preventive maintenance, rebuilding, and alterations.
https://www.law.cornell.edu/cfr/text/14/part-43
This is the regs:

(3,859 posts)I have worked at two airlines and two third party maintenance providers in my career.
All of that work was here in the USA.
The standards vary. It has been my experience that the quality of the final product depends upon the culture of the organization at the time the critical decision has to be made.
Ultimately the safety issue belongs to the person signing the airworthiness release.
I think the oversight of third party maintenance by the FAA is a joke...

(3,859 posts)First we need to find out what happened.
Then we can try to figure out why it happened.
The flight data recorder and the cockpit voice recorder will provide a lot of information.

(26,327 posts)Seems like more of a maintanance/design mystery to me.
Wouldn't there be a more comprehensive engine monitoring system onboard that wouldn't require pulling the "black boxes"?

(3,859 posts)The flight data computer data.
I am only speculating but I am pretty sure there will be more than the usual amount of data to analyze.
The point i was trying to make is that there is an abundance of both electronic and physical data here.

Applan
(693 posts)There are a couple of pressure relief doors on the nacelle which look like they've been actuated perhaps suggesting a bleed system failure. The inlet might have become over pressurized as a result. Of course the relief doors are there to prevent this happening but for some reason they couldn't handle the sudden increase in pressure.
One possible cause.
