South african rules,help

[xabi200]

Hi,

I'm about to do a LET410 type rating with Osmone aviation in south africa.

I won't be able to put the type rating on my UK/JAA licence, but I have been told that it is legal in south africa to fly with a south african validation and the type rating test endorsement on my logbook.

So basically my question is:
"Can I legally fly with a validation and the LET410 type rating test pass on my log book,without having anything put on my original licence?"

Thanks for any point of view.
