Whoops...hope the damage isn't too major
Visibly a bent trim tab on the diesel Katana. Yak will be missing some paint on the bolt cover.
I think that there is some damage to the rudder system on the Katana though, but the Yak most likely escaped unharmed.
If you look at this picture you see that if the prop is in coarse, the balancers are behind the red thing...
