GM 66.A.45(b) Endorsement with aircraft ratings    

CAA ORS9 Decision No. 1

An aircraft type rating includes all the aircraft models/variants listed in column 2 of Appendix I to AMC to Part-66.

When a person already holds a type rating on the licence and such type rating is amended in the Appendix I to AMC to Part-66 in order to include additional models/variants, there is no need for additional type training for the purpose of amending the type rating in the licence. The rating should be amended to include the new variants, upon request by the applicant, without additional requirements. However, it is the responsibility of the licence holder and, if applicable, the maintenance organisation where he/she is employed to comply with 66.A.20(b)3, 145.A.35(a), M.A.607(a), and CAO.A.040 as applicable, before he/she exercises certification privileges.

Similarly, type training courses covering certain, but not all the models/variants included in a type rating, are valid for the purpose of endorsing the full type rating.
