Flyingtonka,
Don't look for that list, there is none. In JAA-land, there are (almost, ik, ik;-) no helicopters CERTIFICATED Multi-Pilot. The great majority of flight hours done in MP Helicopters result from the JAR-FCL 2 reference to '...or requred to be OPERATED MP according to JAR-OPS'. This means e.g. the North Sea shuttles, flying IFR, more than 9 seats, etc.
Beware that the new Amd 4 to JAR-FCL 2 contains a NEW definition of MP helos, extending this a bit.
Hope this helps, and good luck!
Cheers,
