Less than three months to final report. Makes you wonder why it takes others so long.
Because the others do it properly and don't just look for the superficial causes.
yeah, drunk navigator, pilot bust minimums causes crash. end-of. what a load of tosh.
What about the systems that let those people be there with that attitude? what about the society that thinks drinking on the job is normal? etc etc etc.
A decent air accident investigation system that finds the real systemic causes and a culture and society that addresses them is why most of Europe, the US and others have a very good aviation safety system.
Russia has none of those attributes and has the worst, or very close to the worst, aviation safety record on the planet.
I utterly detest the following phrase as its used by all the elf-and-safety idiots but "safety is no accident" is a fairly relevent phrase.
