Regulation (EU) 2023/989

A. Experience requirements

Table A below shows the experience requirements, in months, for adding a new category or subcategory to a licence granted in accordance with Annex III (Part-66).

The experience requirements can be reduced by 50 % if the applicant has completed an approved Part147 basic training course relevant to a particular subcategory.

B. Basic knowledge modules or partial modules required

The purpose of this table is to outline the examinations required to add a new basic category/subcategory to an AML granted in accordance with this Annex.

The syllabi prepared in accordance with Appendix I and Appendix VII require different levels of knowledge for different licence categories within a module; therefore, there are additional examinations applicable to certain modules for licence holders wishing to extend an AML granted in accordance with this Annex to include another category/subcategory and an analysis of the module shall be conducted to determine the subjects missing or passed at a lower level.
