Air France A380 F-HPJC operating AF703 with 501 occupants from Abidjan to Paris suffered engine failure above Niger forced to turn back to Abidjan after fuel dumping.

Early reports from crew indicate engine experiences compressor stall damaging fan blades and engine cowling.

That said, for lack of a better description: looks pretty routine, in that the containment appears to have held.

Though if the statement that a compressor stall is accurate: wouldn't that tend to affect the parts more downstream of the engine core, rather than sending them forward toward the fan?

I guess the pressures are great enough to overcome both the aerodynamic forces + the blades' structural resistance?

https://www.channelnewsasia.com/news/wo ... n-11329626 says:

"We were flying over Niger (to Paris)... I saw a ball of flame for a few seconds and then a large bang on the left side of the aircraft," Baudelaire Mieu, a journalist with Bloomberg News, told AFP.

"The plane began to roll, everything was shaking and people started to panic. The pilot came on and said, 'We have just lost a left side engine. We are returning to Abidjan'," Mieu said.

Mieu said the giant four-engined aircraft, the world's biggest passenger jet, "continued to vibrate all the way back to Abidjan. People were praying".

"It was a close call. I have never been so frightened!"

Looks like AF will be paying a lot of dry cleaning bills.

Engine change and any additional repairs won't be easy in ABJ.
Guess AF will be leasing an AN124 to deliver spare engine soon.

I believe they could also ferry the plane back to CDG on 3 engine.

Yes they could, recently an EY 388 had an engine problem in SYD and they ended up ferrying it back to AUH on 3 engines albeit via SIN, so it can be done

It's possible what happened inside the engine caused so much vibration that the fan hit the casing.

Very little similarity to QF32. Different engine type (AF uses GP7000) and different failures (this was fan blade failure, QF was rotor burst in the hot section). The only similarity is engine failure.

So we have ET, AF and what's the third incident?

Hardly news at all.

Historical/colonial ties, preferred continental base of transit, business ties, limited frequency, and the lower end of market willing to pay high fares + significant baggage/cargo/shipment fees? ...AF and SN have been (for lack of a better word) exploiting this type of service for decades. Same with LAD.


Though what's usually interesting about ABJ, is people will pay top dollar for Y (it's not unusual to see 2wk prepurchase fares in the $1500-2000 range for roundtrip regular Y), whereas C often goes for a steal: that same flight that's selling Y for $2000 is so often selling C for "only" $2500-3000. I've rarely seen it above $4K roundtrip.

LAD on the other hand, is expensive as hell in all cabins.

Correct me if I'm mistaken, but wasn't there an engine incident involving a different AF A388 last year? As I recall, that ship was parked somewhere in Canada for a long time before it was deemed safe to return to France.

Thanks. I couldn't recall the specifics about AF66, so that refreshed my memory.

But the odds of a catastrophic engine failure are twice as high on a four engine plane as they are on a twin. The real danger is an uncontained failure doing structural damage to the airframe, as in QF032, not in losing another engine. Here we have three engine failures on A380s, two of them uncontained, that have made the news, and that is out of a fleet of around 200. Meanwhile, how many engine failures of the 777, of which over 1500 are flying, and have been flying much longer, have made the news? I do not recall any, although I know there have been a few.

BA2276 is probably one of the best known example of a B777 uncontained engine failure.

Very interesting. Wonder what would have happened had the plane been in the air. My suspicion is that the fire, which caused most of the damage, would not have taken hold because the slipstream would have extinguished it. But that is just speculation.

Reporting is strongly partisan.

Not really. Simple IFSDs are not getting much attention, it has to be something spectacular - blade damage and vibration from windmilling or fire/extra damage for such an accident to make the news.

BA38 definitely made it to the news as well..
UA flight to Hawaii was fairly well reported.
Any diversion to the middle of nowhere island in Pacific also gets some media attention.

Are these engine failures in any way related to the type of aircraft the engines are fitted to?
If not, the safety record of the A380 itself (3 major engine failures out of 200 frames) vs 777 is only relevant in a curious statistical way.
i.e. I will not fly that aircraft because it features those engines.

You also missed a trick, which you yourself had referenced. Each of the 200 A380s has four engines, so there are 800 engines available to fail.
This makes the 200 strong A380 fleet equivalent to 400 Boeing 777s. Obviously this is still way short of 1500 777s, so in that part you have a point.

I do agree the RR Trent 900 and GP7000 engines have somehow combined to reflect badly on the A380, but this is partly an illusion. A single failure on the RR engine, and two failures on the GP7000 are in the first place unrelated, and secondly only mildly statistically relevant at this stage. Still worth proper investigation certainly.

My point was to poke holes in the canard that four engines are safer than two. I think it’s the opposite. But it is opinion, I cannot prove it. Your chance of dying is probably greater by being struck by a meteorite than by being killed by an engine failure in a jetliner.

Again, all 2-engine losses I can think of happened because all engines were affected, rather than engines 1 and 2 while 3 and 4 could keep going in same situation.
I can think of 2 relatively recent events on 2-engine similar to magnitude to QF one; those were 2 write-of fs on the ground. What would happen if those were airborne events is a whole different story.
I may ask if primary risk reduction factor of 4-engine is using smaller engines which don't push the limit; but then latest narrowbody engine stories wouldn't support that as well.

Were vibrations subsequent to the engine out due to windmilling of the damaged engine? Or some damage in the engine area of the plane?

Latest must be AF4590, which was effectively a dual engine failure, albeit due to external causes.

There probably are no other recent examples.

Keep in mind that there are probably fewer examples of this because there are also simply fewer four-engined aircraft in the skies. But yes, I like more engines too.

Although not technically engine failure (I believe it was more pylon failure), El Al flight 1962 is another example of engine issues that brought down a four-engined plane: https://en.wikipedia.org/wiki/El_Al_Flight_1862

But that was 1992, and shockingly catastrophic chain of events.
