PashaF, your offer to translate is very kind, thank you. The letter from the MAK/IAC can be seen on the AvHerald website at
News: Russia suspends airworthiness certification for Boeing 737s, but does not prohibit operation of 737s. Would it be possible to translate this letter?
Amidst the disagreements between agencies, I think it would be helpful to know the exactly how the elevators or the pitch control system malfunctioned. (
to be clear, I don't expect the MAK/IAC letter will explain the malfunction - for those not reading Russian it would be interesting to know what it states).
