Quote: An SQ B777 operating on the Singapore - Paris sector made an emergency landing at DEL yesterday at about 1705 local time after the pilot reported trouble in one of his engines.
The plane landed here without incident and the a/c is still hanging about at DEL. The a/c involved is 9V-SWF type B777-312(ER).
Does anyone know more about this incident? Are the pax accommodated in hotels in DEL, or flown to SIN by a spare 777 or the scheduled SQ services on DEL-SIN?

Anyone keeping track of all the 777-773-77W emergency landings? There have been quite a few lately, is this a coincidence? I have been flying 777s since they startrd in 1995 and always found them very relieble.

That one was in March :
Air France 777 unscheduled diversion cause inflight shutdown
Lajes (Azores/Portugal) - An Air France plane makes an uncheduled diversion to Lajes international airport (Terceira Island), in Azores, due to engine mechanical troubles on one of the two engines of the plane during a flight over Atlantic Ocean.
The aircraft, a Boeing 777-300ER, registration number F-GSQT, flight number AF620, which was supposed to operate between Paris-Orly (France) international airport and Pointe-à-Pitre-Le Raizet (Guadeloupe/France) international airport with a total passengers number not know at this present time, took-off around noon and was over the Atlantic Ocean when an engine incident occurred. The pilots requested an emergency diversion to Lajes.
The plane landed without further incident and no injuries. No more information were released by the company about the engine problem. The passengers have been disembarked and placed in some hotels to wait for the next departure, the day after.

If all are considered IFSD (and not determined to be another problem), then the 77W may not keep ETOPS207 or earn 240. I estimate 1 million engine hours over the last 12 month period for the type, and to keep the best ETOPS rating, you need the type to have fewer than 10 IFSDs. We are at that number now, so they are on the verge. I'm using rough numbers, and it may end up being they have a few IFSD's to "spare."
Of all the things to worry about... the Wookie has no pants.

Quoting Aguslamm (Reply 6): something wrong with the engines?
well, considering they are currently within the very stringent ETOPS207 guidelines, claiming there is "something wrong" is a bit much. I mean, it's meeting the most reliable engine standard in commercial aviation!
Now, I am sure that GE is looking at why they are close to the limit here, especially with AF who's had 1/2 of the shut downs. it might be a maintenance issue in the field (something GE wouldn't have found in their test environment with their test engineers babying the engines).

If it was a maintenance issue, AF would have had 100% of the IFSD problems. Last time I checked, AF is not responsible for SQ's B77W maintenance ... Note also that AF operates 24 B773ER against 13 or 14 for SQ so statistically, it makes more sense that AF more incidents than SQ.

The actual flight hours for the type has to be increasing rapidly with many new frames having been delivered and many more to come. The quantity of IFSD's will logically increase while the rate based on flight hours will begin to decrease. Operators are probably still learning the quirks of these engines as well, and pilots will always err on the side of caution when EICAS shows anything abnormal, and rightly so.

This was on the Air Force website also...I'll see if I can find their article.

FAA, EASA, Boeing, and GE.
Quoting Aguslamm (Reply 2): There have been quite a few lately, is this a coincidence?
Yes, based on evidence to date.
Quoting Aguslamm (Reply 2): I have been flying 777s since they startrd in 1995 and always found them very relieble.
They are. They still have one of the lowest IFSD rates and highest dispatch reliabilities in commercial aviation.
Quoting Ikramerica (Reply 5): If all are considered IFSD (and not determined to be another problem), then the 77W may not keep ETOPS207 or earn 240.
You'd only revoke ETOPS rating on the type if the shutdowns were uniformly distributed across the fleet. They're not.
Quoting Ikramerica (Reply 5): I estimate 1 million engine hours over the last 12 month period for the type, and to keep the best ETOPS rating, you need the type to have fewer than 10 IFSDs.
The fleet accumulates about 200000 hours per month, or 1.2 million flight hours per year. That's 2.4 million engine hours per year. You're out by at least a factor of two.

Apparently, I can't do math today.
200000 hours per month is 2.4 million flight hours per year, or 4.8 million engine hours per year.

The comparison between SQ and AF is irrelevant.
You'd have to compare AF's fleet to the whole GE equipped 77W fleet currently in service to bring some sense into this statement, and since AF does not operate half of all GE 77Ws out there, it still seems that they had a large number of all the IFSD despite their relatively small number of 77Ws in operation compared to the worldwide fleet.
It may just be bad luck, but you can't deny facts.
And what makes you so sure that there might not be a fault on AF's part?

The 772 with GE engine was and is not affected as much by IFSD. The 77W is really the one affected by this problem. I doubt that this is a maintenance issue with AF.AF has been operating 777-200 ER for the late 90's with GE engines and I dont recall any real issue as with 77W. AF is also the first airline who took delivery of 77W,dont you think that if mx was a problem,those IFSD wouldn't have happened earlier?? And those IFSD are happening now with SQ,NH (?), same story here, never heard of any IFSD with their 772,but on 77W yes.Are we going to blame their mx also?
The real question is, could it be an issue with the GE 90 - 115 B?? To me It start to look that way.
