First of all, sorry if It was asked before.
I have seen here:
http://www.easa.europa.eu/certificat...t-11012013.pdf
there are two licenceīs type to fly the A109:
If you fly these models you will have A109 Type Rating:
A109 A
A109 A II
A109C
A109K2
A109LUH
And if you fly these models you will have AW109 Type Rating:
A109E
A109S
AW109SP
My question is, for example,if you have an A109 TR you canīt fly an A109E?, do you have to do a diferenceīs course or is it a complete and new TR?, or if you have an A109TR you can fly the whole A109 family?.
