N reg CJ Actual Rules... Bollocks relating to JAR/EASA-FCL Removed
There are two different US type ratings
CE-525 = No you cant fly it single crew
CE-525S = Yes, you can fly it single crew but the occupant of the right seat must hold either a CE-525S, CE-525 Type or Have NO Pilot Certificate or Licence (Including a Student pilot Certificate)
That goes for wherever you fly it.
