AF Lost It's 180 Min Etops For 777..

Wed Nov 28, 2007 9:48 pm

As reported on French aviation forum Radiocockpit,AF has lost its ETOPS 180 min. for their 777 and has to live with 120 ETOPS...
No official confirmation yet,but usually Radiocokpit is quite reliable and fed by AF members..
Not a very good publicity for GE...

.and hopes for additional A340's...

I've just heard the same thing from an AF pilot: AF loses ETOPS 180 for 777 fleet.

Will they now be downgraded to 120 or 138 ?

It's certainly a hurdle for some specific AF sectors such as Caribbean.

I guess some people at AF Industries (maintenance) are going to be in trouble...

Two IES in such a short period is a lot.

Will this effect any routes other than ORY-SXM (and other destinations in the Caribbean) and CDG-SCL?
I can't think of any other routes that would require 180 min ETOPS.

I guess this is due to the IFSD and diversion of 773-ER recently to LED. Does AF actually require the ETOPS 180 for any of it's routes?

The problem is not with GE. It's with AF's maintenance depots.

Once they get their act together again, they'll be granted ETOPS-180 so I don't see them buying/leasing more A340s.

Yes, certainly. It's needed on Paris - Caribbean (operated with 777) and CDG-SCL (777), CDG-ACC (or any countries close to Ivory Coast) but no others. As for Africa and the Caribbean, this will involve longer flight times and more fuel burn, but for SCL it might become an issue as the flight will approach 7500nm.

Not really. One engine failure after how many million flight hours? That proves that the engine is very reliable. I see AF getting 207 ETOPS back soon.

Quoting Beaucaire (Thread starter):

More doubtful than the above. One incident isn't a reason for getting different aircraft. If that were so, they would have dumped all A340's after the YYZ incident.

Theoretical question: if they let the MX do by KLM MX in AMS (familiar with the 777 and GE also) for a small number of planes that need to do the required ETOPS routes, would they get the ETOPS certificate back instantly?

Quoting Putnik (Reply 9):

This is a decent overview - http://en.wikipedia.org/wiki/ETOPS.

The 777 has an ETOPS type certificate and Air France has an ETOPS operational certification. The FAA grants a 180-minute ETOPS type certificate to the 777 while the JAA (the EU agency) only grants a 120-minute one. In order to get a 180-minute type certificate, the operator must be trouble-free for one year.

I am guessing Air France has lost their 180-minute ETOPS operational certification, but the JAA might have pulled their 180-minute 777 ETOPS type certificate. Either way, this busts them down to 120-minutes.

If the JAA pulled their 777 ETOPS type certificate, does anyone know if they have to be trouble-free for another year?

there are plenty of discussion on here regarding ETOPS certification can be 120, 180, 217minutes to fly on one engine to alternate airport...

EX: flight from East cost Usa to Europe will take a northern path so if one of the 2 engines fail or have a problemes they will divert to closest airport that could accomodate the aircraft... YYT, Groenland, iceland, acores, SHH are examples

ETOPS means how many minutes to nearest landable airport one aircraft with 2 engines are allowed to fly.
Air France has had a few engine failures over Russia with the B777 (2 engined) and had to land, that´s why
they now face stricter ETOPS rules?

Hello Beaucaire, I was Starship on Radiocockpit.

The loss of the certification ETOPS 180 means an increase of flight time by 25 minutes on a FDF/ORY, 15 minutes on a PTP/ORY.

Well to add to the ETOPS, in the near future it will be Extended Operations...

as others have said, ETOPS really is for utmost safety. With .002 reliability of 1000 hours ETOPS-120 is granted.

But once AF gets their MX act together, they will regain their ETOPS status.

About the ETOPS regarding the 777, if I remember correctly upon deployment to fleets. The FAA granted immediately 1080/270 ETOPS to all 777s, but the JAA only granted 120 ETOPS later upgrading to 180 ETOPS.

The ramifications of a downgrade in ETOPS certification must be expensive. Are long-haul pilots ever under pressure to keep running a poorly-performing engine....perhaps damaging the engine in the process....to avoid an IFSD?

The 777 itself may have 270 ETOPS, but the airline itself has to earn the right to exercise the privilege. The airline must prove that it's maintenance and operational systems are of a high enough standard that the likelihood of an IFSD is very rare. Boeing may well have designed the 777 to a standard that it can undertake ETOPS flights, but it is up to the airline to prove that they can maintain and operate the 777 to a similar, high standard.

I doubt it. If something like that ever became public I would suggest the airline would suffer tremendously (P.R.) and possibly lose their certification to fly passengers. Rather, I would suggest that the requirement ot be incident-free for a year is motivation for the maintenance departments of airlines to operate at an very high standard, especially regarding long range twins. Well done, FAA and JAA.

It affects the Caribbean most, but obviously not on A340/B747 flights if using ETOPS-120. ACC flights only need to go slightly west to be in ETOPS-120 (at first I was confused about ACC but looking at the Great Circle Mapper, I see that the middle of the Sahara is an ETOPS area, and the only ETOPS-120 land area outside of Antarctica, far northern Canada, far northern Greenland, and some tiny, airport-free islands. SCL flights will need to fly slightly southeast of normal, but on such a long flight that sort of diversion doesn't add much length to the route, relatively speaking. However, if they get ETOPS-138, the ACC restrictions are gone and the SCL restrictions are smaller, but the Caribbean is still affected.

I agree with Goldorack in that there is no question about AF-maintenace capability..
AF have never had any issues with their A330 fleet and no IFSD's on those flights.AF maintenance is as good as any maintenance could possibly be.
But their 777's do use a specific GE engine that for some reason seems to have a worse MTBF than other engines.
The incident in St. Petersburg has clearly been affected by external events (be it hail,birdstrike or any other form of mechanical ingestion ) so it's bad luck that this incident appears on a 777 with GE engines,but in that particular case the conditions of the compressor-blades ,holes on the forward-trailing edge of the wing and disruption of horizontal stabilizer joints speak a clear language.
My initial comment about GE's credibility is therefore in this case not applicable.

Quoting Putnik (Reply 9):
How an airline lose, or for that matter obtain ETOPS certificates?

Each airline registers its aircraft in a particular country, that country local CAA issues an ETOPS approval as part of the air operators certificate (AOC). It generally an attachment or condition placed onto the AOC, not a certificate in its own right. The AOC is the overall approval for the airline to operate, it includes they types of aircraft, ports/routes, and restrictions or approvals like ETOPS.

The process for obtaining an AOC is long and expensive for an airline, generally the airline has to document all its processes and procedures and show that it has adequate staff and systems in place to run an airline.

ETOPS is an operational approval which is added to an AOC. When applying for an ETOPS approval, the carrier will have to specify the aircraft type, routes, diversions, staff, training, and maintenance systems in place, and generally also requires demonstrate over time that the systems and processes are working to get an increases in the range they are allowed to plan on one engine.

Quoting Putnik (Reply 9):
How can it drop from one ETOPS to another?

Just approach the local CAA for an increase or downgrade, or the local CAA may impose a downgrade on the AOC at any time by revoking the approval..

Only downgrade I can remember of late was DJ. ETOPS parts are more expensive, DJ said it could not justify the gains made by ETOPS approval (shorter flight paths) against the additional maintenance costs.

The 777 does not have "ETOPS operational certification", it has been "found suitable" ETOPS, but the TCDS clearly says "This finding does not constitute approval to conduct 207-minute ETOPS operations."

It is probable that as a result of IFSD an investigation was started into maintenance procedures (probably only regarting the a/c involved) and some issues may have been found. As a precautory measure, ETOPS-180 certification is revoked.

Another possibility is that there were already minor issues detected that did not prompted by themselves to revoke the certificate. However, after an IFSD incident, the certification is revoked.

If the IFSD was indeed as a result of a birdstrike or any other non-maintenance issue, then the certificate would be reinstated straight away after the investigation is concluded.

As far as I remember, Etihad encountered the same problems as AF with the same type of GE engines on their 777s.

Sorry but I lost track. Revoking the AF ETOPS certificate follows an IFSD after hail-damage or a bird strike. Etihad has "the same problems" so do you mean hail and birds? Or what? What are you trying to say Flying Belgian?

Quoting Beaucaire (Reply 38):

Beaucaire, is that to imply GE is at fault? At the same time you say it was external events that damaged the engine, not an MX or design issue. I'd say although very rare, IFSD's happen. And it is no statistical impossibility that you have no accidents in 5 years and then 2 in one week; authorities should see through that. If it's 10 times black in a row with roulette... Well, you know the rest.

I have the feeling a lot of conclusions are being drawn prematurely.

I clearly state in my last post that I think in this particular case the damage on the aileron (hor.stabalizer ) seems to indicate some form of projection or impact with any unknown item.
So it is clearly premature to assume the incident on the St.Petersburg landing was due to an engine failure but COULD have been caused by external cause.
The picture of the compressor-blades speak a quite strong language-as does the picture with the hole in the wing.
But we are all speculating at this stage-that'w why I regret my initial rermark about GE in my openig post.
It's nevertheless strange that incidents involving GE engines have struck 777's of Air France,Ethihad ,Malaysian ..

Quoting 2H4 (Reply 24):
The ramifications of a downgrade in ETOPS certification must be expensive. Are long-haul pilots ever under pressure to keep running a poorly-performing engine....perhaps damaging the engine in the process....to avoid an IFSD?

I have no idea on your exact question but I read an interview once with a CO captain when they started flying HKG-EWR on their B777-200ER. The captain replied that they monitor the engine very closely on this flight, but it could be because its a polar route (The engine could freeze). I wonder if CX pilots who fly JFK-HKG feel the same way on their A340-600?

Could somebody please clarify this for me: Is a plane specifically etops equipped? This does no longer shows on AC's website but they had a mention on the fin number's page about 2 of their A319 (previously used on YYT-LHR)

Quoting Worldrider (Reply 36):
ans for what reason? do you remember the cause of that accident?

Yep, pilot error. If the OP thinks more A340's should be bought because of a maintenance error instead of manufacturing, then a few years ago more 777's should have been bought because of pilot error.

Not the A319, but some aircraft like the 787 require the installation of additional fire bottles if you seek to gain the higher time ETOPS approvals.

The problems that EY found were following an inspection of the GE engines, not after an IFSD. Here is the tread:

How many airlines this year have lost ETPS approval or had its ETOPS rights amended? AF is one of them now, and the only other airline I can think of is Flyglobespan even though their case is totally different as it applied to the entire GSM fleet.

Thanks for your answer Zeke, but could you please explain "Not the A319" . I am asking that because out of the whole AC A319 fleet, only two can fly with Etops approval.

That would be their choice, if you have ETOPS aircraft, all the parts are more expensive than non ETOPS aircraft (due to quality control). On a non ETOPS aircraft you could for example get the same mechanic to top up the engine oil on both sides, with an ETOPS aircraft, you need to have separate people doing each side to avoid repetition of errors.

From a flight crew point of view, from memory it requires a HF check, and making sure the cross feed works on the ground before leaving on an ETOPS flight.

The A320 family is only capable of 180 minute ETOPS, it cannot be extended by adding addition equipment as far as I am aware, and for an aircraft with a 5-6 hour range, why would you need it.

I would think that the maintenance and performance records are scrutinized to both obtain and maintain ETOPS certification so such a tactic would not be beneficial, would it?

Quoting Milan320 (Reply 33):
No, it just couldn't be an engine issue could it?  Yeah sure

Considering how many GE90 series engines are in revenue service today, if there was a design flaw you'd think nobody using them would have ETOPS-180 or ETOPS-207 certification, would you?  Yeah sure

Quoting Zeke (Reply 34):
The 777 does not have "ETOPS operational certification", it has been "found suitable" ETOPS, but the TCDS clearly says "This finding does not constitute approval to conduct 207-minute ETOPS operations."

I'm just going with what Wiki says, so if it is wrong, I recommend you submit a clarification/correction to the article in question.

I tried to find an ICAO ETOPS document, but was unsuccessful, so I had to go with Wiki.
