Hello
I have heard that there flies at least 4 Pik-20B: s with winglets in
Australia.
I have some questions about this:

1. Is there an approval, similar to a Supplemental Type Certificate
(STC), issued by the national airworthiness authority; ore is the
modification "experimental".

2. Are they sold as kits? What does the installation involve?


I would also appreciate some pictures.
