Its a storm in a teacup. There is an AD to examine and replace a bracket.
There is multiple redundancy so even if the bracket failed it would still be safe.

See post #14 above.

They must have done their maths.

Sukhoi used very agressive pricing to win the first western customers, including serious paybacks in case performance guarantees were not met (they weren't...). With the right figures, the maths are indeed probably good...

Saw one last week in CDG terminal 2G .

None of the three appears to have flown in the last few days, though that may not be significant.

Indeed. And they were also not able to guarantee that no 'Monday Morning' components were included in the assembly, because of poor working practices and poor management oversight. You only had to stroll around a USSR factory to see why that was - if the factory was dingy, dirty and rubbish strewn, what chance was there for consistently perfect component manufacture?

So yes, most USSR aircraft were designed to be bullet proof, as is witnessed by the number of Tu154 fuselages that survived a crash.

Interjet Su-100 are flying
 
Interjet Su-100s are flying today, December 26......
Of course no one will mention that Interjet is quite happy with theirs and ordered more after receiving its initial batch.......

The Mexican press certainly mentions part of the Interjet fleet being grounded:

Interjet anuncia posibles demoras por revisión rusa - La Jornada

Of course that only affects aircraft until such time as the AD has been actioned.

Great journalism indeed!


Mexico City. Interjet announced that its customers could suffer cancellations or delays, because part of its Superjet 100 fleet will be grounded to be inspected at the request of the Russian Aeronautical Authority, following the crash of a Russian aircraft that was traveling to Syria, an accident in which 92 people were killed.

Namely, they deny facts and make up ridiculous stories to support their weird world views.
So where is your proof that whole SSJ fleet is grounded? Or CityJet and InterJet papers are communist propaganda too?

And if you read a bit into Russian economic of domestic and international flights you will understand why Aeroflot is not happy with short range jets and constantly cancels flights (not SSJ performed only).

You mean apart from the AD reproduced in post #14 that grounds all RRJ-95s (not just specific msns) upon return to base until inspected with no cracks found ?

Where did I say that the whole fleet was grounded? I didn't.

The whole fleet's certainly not grounded...

Cityjet's EI-FWA seen today, flying...

Exactly.

The Russian market has been suffering severe retrenchment/downsizing since the beginning of the international crisis over Ukraine, and the halving of the value of the Rouble and Hryvnia.
Some went under, some like EJ > MOW, stopped altogether.

AFL are looking by all means to keep market share & flying full, which helped them with the disappearance of their competitors Transaero and near disappearance of UTAIR.

Now you have a near monopoly/cartel between just 2 carriers, S7 & AFL. (via Rossiya & their horrible lo-cost Pobeda).
It has ending up turning to a turf war over, hub and feeder networks, based at opposite ends of Moscow, fuelled by more speculation and politics.

If anyone has the unlucky experience of having to go from SVO to DME in the middle of winter, one can easily see the low priority accorded to service quality & customer interests in Russia.

The government strategy to try to strangle DME & create one giant government owned cartel with VKO, SVO, DME hasn't worked,-
So the next target has got to be a/c.

The first easy target would be SSJ100, which although it can fly full at 88 easy, & is cheap, has like most new jets had a troubled start.
AFL, never people to be particularly discrete, is mostly government owned.
SSJ is mostly government financed.

Anyone who has followed the catastrophic mess over Baikonur v Vostochny will understand.
high media interest/bad news = politics again, = behind the scenes "turf wars" in Kremlin circles.

Of course, nobody is taking risks so TU204 is an a/c nobody wants, and nearly all those who bought went under.

All S7 could reply with is, A319 which carry minimum 125+, so fly half full and you're losing a lot of money.
They planned to downsize with Embraer, E170 E series in 2016 but it won't be flying for a while.

SSJ at under 100 in use (prod 2004), is a clear FAIL compared with Embraer 1000+ (prod 2002).

It really doesn't look good for the "revival" of the fortunes of the Russian aircraft industry.
Too much "krym nash", wasting time, and precious resources, flying people to places that are black holes for political reasons.
A good read,- https://jamestown.org/programs/rd/

SSJ was supposed to be the flag bearer, but as most things in Russia these days, - the vodka, cheese, you name it, 50-75% of it like the news is fake.
The only thing you can pray for, nobody puts formol in your fish or methanol in your vodka.

After spending four days on the ground at DUB.

The grounding, which did affect the whole fleet, only applies until the inspection is carried out (assuming no cracks are found).

It's all there in the AD (see post #14).

ChiefT 28th Dec 2016 08:02

Well, the SSJ is flying (again). I am about to board and Aeroflot flight to Moscow. RA89061 is the registration.

Glad to hear it. As a passenger, it's one of my favourite aircraft to fly on.

The SSJ has without any doubt, one of the most ergonomically well thought out interiors in the world.
It "feels" a lot bigger than it is, and is more comfortable than any other I can think of.

The only criticism, you may have is under adverse weather, as it's a good deal more skittish than larger aircraft, but hey, it's NOT a large aircraft. :rolleyes:

Russia Grounds Sukhoi Superjet 100 Over Safety Concerns
It's about time an adult is put in charge of correcting misleading headlines on PPrune!

The AD issued by the manufacturer seems very clear to me - its a one-off inspection before further flight, followed by daily visual inspections followed up with a weekly NDT inspection. This would not generally call for any press comment, except an item in an aircraft maintenance digest.

No wonder the Russians are paranoid about how their communications are misrepresented in the Western press. The BS on this supposedly professional forum is shocking, to say the least.

Western press misrepresentation is not biased toward Russia. The western press generally misrepresents almost everything, EAST and WEST!!! Headlines sell newspapers. Oh, and are you trying to say that the Russian press doesn't misrepresent the west? They're even worse!

~20% increase in domestic flights in 2016 YoY
~10% decrease in international flights, mostly due to Turkey/Egypt ban
