Lomcovac,
Try looking at CAA Information Notice 2012/146
IN-2012/146: Changes to Instructor and Examiner Qualifications for Single Pilot Aeroplanes | Publications | About the CAA
If you were instructing on the Kingair as a CRI before EASA you should be issued with a TRI when you convert your JAA licence to an EASA licence.
All the best
