As stated on an earlier topic, although the GE90-115B had a good first 3 years with no IFSD, they have now had 5 in the last 5 months. (Reply 33)
Do you have a reference for the 5 IFSD's in the past five months? I believe the number is 3 IFSD's total.
This leads to the .0023 IFSD per 1000 engine hours I calculated in Reply 25.
How many engine hours are you using in Reply 33 to get a .015 per 1000 rate?
Besides, is it really true that AF has lost 180 min. ETOPS for the 777? There are some comments that say they haven't.

ok, lets talk dirty
Air France has not lost any ETOPS agreement, period !
sorry to speak up about such a stupid thing, this story is full of b......it
the (false) rumour starded in France, through several air community information sites, blowing more and more air as time went by !
This story just needed two or three writers, well known in the internet community , on A-net and on the french 'pro pilot' site ... and that was enough to do the trick... and start the worldwide tornado on the net !
we have all been tricked, like it or not, that's a fact

- June 07 Air France, IFSD Diversion to Guadeloupe
- August 07 ANA, IFSD return to Narita
- Sept (30th 07) ???, IFSD, ??????
- Oct 07 Emirates, IFSD, return to Bankok
- Nov 07 Air France, IFSD Diversion to St Petersburg
The 0.015 I quoted was for the hours over the 5 months they have had this bunch of IFSDs (I'm sure that's the way the authorities will view it!), the calculation is shown in the post.
I have no idea about whether the AF ETOPS downgrading is true, but I am sure they have looked closely at it, especially if they have had 3 rather than 2 .

Although stated earlier, only now I fully realize the "5 in 5 months". Is there more information about the other four events? Even of the type "understood / being adressed" or still unknown reason?

New IFSD
Who knows what truth there was in the Air France ETOPS rumour? Looks like that will all be surpassed by what has happened yesterday (see link).
It now appears that AF have had another IFSD, this time diverted to Rome. By all accounts (and who knows what the truth is) this is also a 777-300ER. This would make a sixth IFSD on that type and that engine (GE90-115B) since June 2007, three of them with Air France!
What is going on? This has got to be of concern to AF and DGAC surely.

Two Air France B777-300ER planes grounded in two days
Source; http://www.crash-aerien.com/www/news...d=7193&check=0
Paris (France) - For the second time in two days, an Air France B777-300ER plane has had to canceled its flight, the first one was headed to La Réunion and made an emergency landing in Rome-Fiumicino airport, the second one to John F. Kennedy Airport in New York but didn't take off, due to engine problems.
The first flight, between Paris-Orly and La Réunion, a french island in Indian Ocean, was diverted and made an emergency landing less than two hours after take-off in Rome-Fiumicino (Italy) because a technical glitch on one of its engines. After that, an inspection was conducted by the french company to check every GE90-115B engine through the Boeing 777-300 fleet owned by Air France.
A non-confirmed information given by an anonymous source link this inspection to the cancellation of the second flight, AF8, between Roissy-Paris airport and JFK-New York. Something wrong would have been found and the technicians wouldn't take the risk to authorize the plane to fly in that condition.

We still have ETOPS 180.
4 B773 grounded after inspection of all GE90-115B.
Problems with LP turbine 6th stage fins.
Spare engines available, will take roughly a week to change them all.
cheers

Re: alcorfr
merci monsieur! Quite a busy time, was the inspection triggered by the latest FCO diversion? I take it that the root cause (sic) is not known yet, but there is confidence that after this inspection, no problems should arise in the short term? And out of curiosity, a long time ago derated thrust was not allowed for this engine at takeoff, to avoid some software problem and potential loss of thrust ... is this still in effect today?

pax2908,
yes the inspection was triggered by the FCO incident and when GE/AF maintenance found it was the same problem than in LED.
Problem is identified, engines beyond tolerance are removed, and i guess things will be thoroughly analysed by GE
The derated bug has been corrected a long while ago.
Cheers
