This is the same MAK/IAC that is currently investigating the A321 crash in the Sinai? The one whose chief investigator wasn't allowed to visit the crash site and returned to Russia? Not a confidence builder in my book when playing politics gets this crazy.

Just a bit of Conspiracy theory
1) Head of MAK is mother of Transaero owner
2) She also rumored as recently ceased ex-prime minister common law wife
PS: Letter to FAA from MAK cites Kazan crash

What about the rumour that all foreign registered aircrafts should be reregistered in Russia?

Isn't it standard procedure, in the event an actual design flaw is discovered, simply to issue an airworthiness directive? I did a bit of googling and it seems that revoking a type certificate for an aircraft that is still being supported by its manufacturer is an unprecedented move.

I guess Boeing will be closing their 737NG training facility before it's even finished. The stupidity that exists in this country is even grater than the US...if that's possible!

MAK's suspension of the 737 was reported, without comment, on NHK's English broadcast this evening. I wonder if Boeing will even bother to try to explain this to the US public or just assume it will get lost between "Dancing with Stars" and "The Voice".

repost from russian aviation forum, supposedly it's a summary of MAK's concern:
"There are cutout switches available on the pedestal to stop a stabilizer trim runaway. It's really important that the autopilot self test is carried out regularly on the ground by maintenance. However, you can get a stabilizer trim runaway when an autopilot is engaged if maintenance has installed the elevator position feedback link in the wrong way around. This manifests itself as a nose down uncontrollable trim which, when the autopilot is disconnected again, needs to be manually trimmed out or the elevators will not be faired with the stabilizer. Remember there are stab trim lights on the instrument panel that need to be taken seriously."

According to this report Russian airlines are carrying on operating their 737s regardless.
The article goes on to say:
"Russia’s Federal Air Transport Agency has refused to budge, saying it alone is empowered to halt foreign aircraft operations in the country and the committee, known locally as MAK, lacks the authority to issue such a ban. The agency’s chief, Alexander Neradko, said MAK revised its earlier statement on the Boeing 737, and Russian authorities see no reason to call for parking the single-aisle planes."
It all seems like internal politics and nothing particularly to do with the 737.

According to newspaper:
There were several disaster of 737 in the US that had unknown cause in nineties. Finally low temperature problem with hydraulic servosystem of elevator was found.
In time of investigation of Kazan disaster, MAK sent a question to FAA/Boeing if related hydraulic part of involved aircraft was replaced or not. Till now they have got no concrete answer, so they can not say, what 737 are safe and what not. Maybe they try to force Boeing to answer.
This episode is little confusing but by my opinion, investigators of MAK are very competent

Transaeros revenge failed

TASS: Business & Economy - Boeing 737 to continue operating in Russia ? air transport agency
MOSCOW, November 6. /TASS/. Operations of Boeing 737 aircraft will be continued, Head of the Russian Federal Air Transport Agency Alexander Neradko said Friday......
For a few hours on Thursday, Russian aviation authorities appeared to have banned Boeing 737 short-haul airliners.
The surprise move by the Interstate Aviation Committee (IAC) — a body that investigates air accidents in a clutch of former Soviet states — could have caused havoc, grounding nearly 200 planes, putting half of Russia's airlines out of business, and curtailing air travel inside Russia, the world's largest country.
Within hours, it had unravelled. Russia's Federal Air Transport Agency, Rosaviatsia, said no decision had been taken to enforce a ban. But before it did so, industry insiders said the move was corporate revenge, and it emerged that it might not even affect Russian airlines, since 85 percent of their planes are registered in places like Ireland and the Bermuda Islands..

The suspension, such that it was, appears to be over.
From FlightGlobal
"Rosaviatsia says the meeting was “unanimous” in determining that there were no grounds, at present, for halting the operation of 737s registered in Russia and other states.
“Operation of the Boeing 737 in Russia will continue, on the same basis as before,” it adds."
I hope that this means that the report into the Tatarstan 737-500, VQ-BBN, can now be released.
Such political posturing does nobody any favours, especially not the families of the victims and those wishing to learn from the final report.

Not that I'm particularly looking for airplane registrations/tailnumbers, but the Gazpromavia 737s seem to be the only RA-registered 737 in Russia that I've spotted, all others aww VP, EI...
