Ist a shame i couldnt read the Accident Report, but the Cockpit Pictures brought up a Memory of the past:
I have flown the AN2 for 10yrs. in my sparetime for Sightseeing flights.
A friend of mine operated 4 of them on an AOC in Germany.
When we arrived at an Airshow often we did a Flyby with some manouevering before we landed and prepared our Sales Stand.
One day after the low pass i pulled up and turned to the right doin app. 250kmh and was greeted by Buffeting until the slat came out.
The next Thing to remember is that a Coordinated steep turn in an AN2 is "NOT" Rudder neutral. Above a moderate Bank you Need In Turn Rudder and Out of Bank Aileron to get the ball centered. This is because the AN2 has a Spiral Dive Tendency in steep turns. This amount of Aileron is already subtracted from your Roll Authority.
Also to get a bit more Rate of Roll i used sometimes a big boot of Rudder, which boosted Roll big way ( Only when playing around, not on Commercial Flights).
The Ailerons are both Sloppy and heavy. And in this Special case nobody knows how well the Accident Aircraft was maintained especially Cable Tension.

Welcome to PPRuNe Propsforever, thank you for the insight. It's always nice to hear from pilots with experience flying types less common to some of us "western" pilots!

Pretty strange to be doing aerobatics in a plane like that at an airshow when you haven't flown the aircraft type in years. Interesting about the cable slack affecting the ailerons. but it appears that the real mistake was upon discovering that he was closer to the crowd than desired, he pulled too hard and lost control. In the end, just fly safely over the crowd if you made an error instead of doing something drastic and crashing.

Thanks for that excellent video Punkalouver.. A good demonstration on how Russian general aviation was regulated in 2017.
Banking 60 degrees just below Vne on a cable driven aircraft would need quite some muscles and , from what the description is , the cables might just slide on the pulleys , and the forces on the control surfaces keep stuck on the last input . I experienced that on a Super Cub when I was younger and more stupid, Not a pretty feeling I can tell you.. ,.
I flew (briefly) the Ans 2 in Poland in the early 90s, very easy to fly , cannot really stall like a normal aircraft , more like parachuting down, and it can fly very slow (55Km/h) but one thing one should not do is fly fast. At least that was what the Polish FIs were telling us never to do. As to performing aerobatics like on this video, crazy to attempt from the start.....
