Russia's Interstate Aviation Committee (MAK), equipped with this power by Russia's Ministry of Transport (Rostransnadzor) and Russia's Civil Aviation Authority (Rosaviatsia), have decided to suspend the airworthiness certification of the Boeing 737 family stating that deficiencies in the aircraft's elevator system need to be addressed before safe continuation of operation can be ensured.
The MAK argues that on Oct 9th 2015, after receiving according requests by Rosaviatsia, the MAK sent out inquiries to the FAA, the reply from the FAA received by Oct 27th 2015 however was not able to remove doubts on the safe operation of the elevator system of the Boeing 737 family.
The MAK further elaborates that for more than a year the MAK was working with the US Authorities already to review and address issues in the elevator system, however, the MAK did not become aware of any modifications having been done during that time.
Therefore, as the safe operation of Boeing 737 family aircraft can not be ensured, the operation of all Boeing 737 family aircraft has been suspended in the territory of the Russian Federation. The Civil Aviation Authorities of Ireland and Bermuda, many aircraft operated in Russia being registered by these authorities, have been informed about that suspension of airworthiness certification too.
At the time of the release of this letter the investigation into the crash of a Tatarstan Airlines Boeing 737-500, see Crash: Tatarstan B735 at Kazan on Nov 17th 2013, crashed on go-around, is going to conclude, comments from the parties involved were collected and a final report is due. The letter however does not state what the deficiencies identified are and whether the decision is linked to that crash. The MAK had reported in 2014 that there were no technical issues identified, however, also stated in 2013 during the course of the investigation that after the autopilot was disconnected, the stabilizer trim - most likely automatically - wound down (which, after autopilot disconnection, would mean a trim run away).
Che è sta cosa? Tutti i 737 sul suolo russo restano a terra??
Probabilmente nei prossimi giorni viene fuori che Aeroflot ci ha ripensato ed ha deciso di acquistare Transaero.......................
Sti Russi dovrebbero darsi una ridimensionata.
"Russia's Ministry of Transport stated in response to the letter by the MAK, that the "MAK can not stop the operation of the Boeing 737 by Russian airlines by its decision to revoke the airworthiness certificate. Only a specially empowered federal executive authority can prohibit the operation of a specific aircraft type. This authority has not made this decision...
.....Russia's Rosaviatsia announced in the evening in response to the letter of the MAK on the MAK website, that Rosaviatsia have not received the original letter so far, but were e-mailed a copy from Rostransnadzor, in addition the letter was posted on the MAK website. "Given the seriousness of such a notification Rosaviatsia is going to hold a meeting on Nov 6th 2015 with Russian Airlines operating the Boeing 737 together with the heads of the MAK." Rosaviatsia pointed out that Rostransnadzor had already stated that the MAK can not prohibit operation of the Boeing 737 by revoking the airworthiness certification, only an accordingly empowered federal agency can do so."
