Operated by LET-Aircraft Systems on a sales tour of Australia from this LET-420. 3 Airlines were interested in the aircraft but nothing was finalized.

Used for humanitarian relief work by International Comitee of Red Cross.

The prototype L-420 (actual type - L410UVP-E20) came to the Australian International Airshow, operated by manufacturer LET Kunovice. It was later registered in the USA as N420LW, later N420Y, and five years later returned to Australia in this guise on another demonstration tour. Sadly this came to nothing and in 2001 the aircraft was exported to South Africa as ZS-OSE. So far, it appears to be the only L-420 built.
