The plane in the incident was sold on gumtree not too long ago, I think it is a SK, not a UL, probably similar to a UL,I’m not sure.
What I do know is that it had a very small tail fin and rudder, much smaller than the J120, and needed a lot of rudder input controlling it at slower speeds, during landing especially. It could be a handful for a pilot unfamiliar with this plane. It was a 20kt croswind at Caiguna airstrip, the J120 with bigger rudder can handle 12kts safely according to the operating manual, not sure about the SK.
It had a Jabiru 2200 engine. To my knowledge the airframe and engine had less than 100hours total, it was not used much during it’s life, a few hours every year. It was only a cheap aircraft, 20K or so, can’t expect it not to be ‘rough’ I guess.
at this stage we dont know if the incident happened at the runway or not?
