‘Acceptable Means of Compliance and Guidance Material to Annex VIII (Part-CNS) to Regulation (EU) 2017/373 — Issue 1, Amendment 1’ Annex VIII to ED Decision 2017/001/R is amended as follows: The text of the amendment is arranged to show deleted text, new or amended text as shown below: (a) deleted text is marked with strikethrough; (b) new or amended text is highlighted in blue; (c) an ellipsis (…) indicates that the remaining text is unchanged.

N o t e t o t h e r e a d e r

In the amendments, and in particular in existing (that is, unchanged) text, the term ‘Agency’ is used interchangeably with ‘EASA’. The interchangeable use of these two terms is more apparent in the consolidated versions. Therefore, please note that both terms refer to the ‘European Union Aviation Safety Agency (EASA)’.
