This was going round on pilot forums. I know Eddie has seen it. Note that the instructor dies in the crash. Crash occured a few days ago.
I think the main safety lesson here is to stay on the centerline until climb rate is assured. The whole thing was precipitated by turning away from the runway. And if you crash, try to crash wings level.

Re: Fatal(1) Evektor Harmony in Russia
Just copying and pasting my first reply to the video on POA:
Scary.
The throttling back seems very, very counterintuitive.
I've been in that same situation numerous times as an instructor, and my reflex is full power, whatever right rudder it takes as the nose is aggressively lowered - even if ground contact is inevitable.
Several Cirrus's have come to grief in smoking holes to the left of the runway after botched go-arounds. I was the only thing that prevented one in an SR22 at Copperhill, TN. When surprised, pilots will often try to "steer" away from the left yaw with aileron, and are reluctant to lower the nose and stomp the rudder. Natural reflexes are all wrong when things go south like this.

Re: Fatal(1) Evektor Harmony in Russia
We need to ask Paul about this as out ultimate expert in Evektor. However, I should note that when I came back to flying GX, I had to unlearn the rudder-stomping consciously. In particular when we went to do stalls, I found that rudder does very little when a wing drops in stall. In the same time, it was trivial to pick it up with aileron. Yes, in a stall! We did several so I could confirm. It's basically an airplane that rewards the "incorrect, naive" behaviour. I'm wondering if Evektor is like that too.

Based on their track record, the other lesson is not to fly an Evektor.

Re: Fatal(1) Evektor Harmony in Russia
No, Pete, the Evektor responds appropriately to rudder application with a low wing. Since this is counter-intuitive, let me explain how this works:zaitcev wrote:I'm wondering if Evektor is like that too.
Say, a wing drops, with the angle of attack so high that the wing is near a stall (i.e., the ailerons are ineffective). Stomping rudder aggressively on the side away from the low wing causes the plane to yaw in the direction of the applied rudder. As the plane yaws, the low wing is accelerated, and the high one is slowed down. This causes more lift on the low wing, and less on the high one, which raises the low wing and lowers the high one.
Now, the only trick is to neutralize the rudders as soon as the wings come level. Otherwise, you've overcontrolled, the other wing drops, and you have to repeat the procedure in the opposite direction -- leading to the kind of dance with which most taildragger pilots are familiar on landing.

Re: Fatal(1) Evektor Harmony in Russia
From the pull-quote in the Aviation Consumer article:
Could it be that, when the article was written, those three aircraft were the most widely used in flight schools for primary instruction?
BTW, the word "data" is plural (data are plural?) so that should have said "The data show..."

Re: Fatal(1) Evektor Harmony in Russia
Very disturbing video. Seems like the instructor should have been on that before if not immediately after the student left the runway. Geez!

"Data" is accepted as a "Collective Noun".

Maybe in England. What do they know about our language?

Excellent! Glad to see that you have the verb properly agreeing with the subject, rather than with the noun in the prepositional phrase...SportPilot wrote:The bucket of data shows...
