The (temporary) civil registration was applied as a trial for a new flight school, if my memory doesn't fail me. It seems that it wasn't successful as the Supporter was soon seen again without the civil registration.

The Luftforsvaret once operated 22 Safaris with the Luftforsvarets Flygeskole (LFS) from homebase Bardufoss. Through the years four were written off during accidents, two became an instructional airframe (possibly after an accident too) and one was stored and cannibalized after an accident. So the LFS nowadays (2020) flies with fifteen Safaris, including this one, furnished with an aggressive looking sharks mouth.
