Quoting CHRISBA777ER (Reply 1): Havent AF been having a load of IFSD problems with their GE90s recently? - i seem to recall two AF flights landing with one engine at MXP recently.

At least that explains the SQ B777-30ER that I saw parked here when I left for Zürich on 30 January... I wasn't paying attention when I came back yesterday - am I right in guessing that it's since returned to SIN or carried on to CDG?

In the past two months, there have been around six incidents with B777 and emergency landings... four AF, unfortunate incident at LHR for BA and now SQ. AF had two em. landings in Russia (might be wrong, but I am certain of at least one) and FCO / MXP incidents.
Isn't it a bit odd that B777 as has these issues - we're not hearing about B747, B767, A330 having emergency landings due to a plethora with what seems to be engine issues (might be off on this one, but still...).
Winter 2007/08 will not go in good books for two long-haul birds, the A340 and B777. Hull losses from both sides (Etihad A436, anybody knows the status of Iberia A346?), BA will prolly write this B777 off, and these emergency landings.. just weird.
There's no better way to travel than fly (shameless rip of LH's slogan ;-)

Whenever I see a thread like this I am wondering - where are all those people claiming that twins are actually safer than quads and that on this planet, twins never have to perform emergency landings due to engine failures now? (Literal quote from another thread.)

IFSD != unsafe aircraft.. hence twins are just as safe as quads.. (we don't know what caused the incident @ LHR, but it's entirely possible it could have taken down a quad too). Last time I checked none of those IFSD resulted in anything other than emergency landings and minor inconvenience (i.e. no one bit it).
Additionally if we exclude AF we have one SQ incident and one very bizarre BA incident...
I don't care what you think of my opinion. It's my opinion, so have a nice day :)

What is not clear in respect of the AF shutdowns as reported in this list, is in some of the postings, the type of 777 involved . The point is that the engines , while built by GE, are different between the two types of 777 in the AF fleet.
Thus it is misleading to simply state that AF have had "X" shutdowns without identifying which 777 model was involved.

Dont know the answer myself but am wondering if any MX people out there can advise if Boeing/GE issue periodic software updates that are input into the aircraft/engine computers? A bad software update (i.e., bad piece of coding) could be responsible for this maybe?

wasn't there a QR and CI A330 with Ge engines where they had both engines flame out?

All of these in flight shutdowns are odd... the engine makers like to brag about their impressive in flight shutdown rates... so this many incidents will be investigated by all of the engine vendors. Actually, pretty much every in flight shut down is investigated.
GE does have the least 'flame out' margin of the three engine vendors. Note: I'm a combustion engineer... so this isn't wild speculation. Why ? Its part of the pollution mitigation strategy. A leaner 'dome' can be used to mitigate smoke in the engine. Once you have low smoke, its easier to engineer away NOx. But it is done at the cost of tougher relight. But I really don't think its the cause... otherwise we would have been hearing about this for years.
I wonder, in today's high oil price environment are quality controls on the fuel slipping? Is water getting into the fuel? Note, I'm speculating... usually there is a cause to increased in flight shutdown rates, but I do not know the root cause, so I speculate. But that's what a.net is for!
Apparently their second in a week, I heard of another one that diverted into TPE before this.

They also happen, most IFSDs don't make it on here. The 777 has had some bad press of late so the spotlight is on. There was a time when RR had a similar run of problems on the Trent 700, the CF6 has had it run of problems as well.

Never met a pilot who wants fewer engines for remote area long haul flights.

Apparently AF have had 6 gearboxes failures on the GE90 alone.

Quoting Flipdewaf (Reply 7): Thats right, if we ignore some of the problems we have less of an issue. Wink .
My point was more that the AF issues seem to be statistical anomalies. AF just don't operate THAT many 777s as to have such a monopoly on the issues. I wasn't suggesting that we throw them out, I was just trying to point out that we've had what 6 'issues' of late.. but as a percentage it's still very small, and we don't even know what caused the most major (and the only really serious one).
I don't care what you think of my opinion. It's my opinion, so have a nice day :)
