FAQ n.19435

What documents need to be transmitted by the STC applicant to EASA for the aspect of EZAP/EWIS ICA?

Answer

For design changes that do not require a revision to the existing EWIS ICA, a statement and justification explaining the rationale for the “no change to EWIS ICA” is expected in accordance with the available guidance material. 
If the process identifies that new/updated tasks are needed, they must be clearly identified as EWIS ICA tasks. The EWIS ICA should be submitted to EASA as part of the compliance demonstration. The associated justification can be, for instance the updated EZAP analyses or an analysis in accordance with Appendix B in FAA’s new AC 25-27A, when the TC holder’s EZAP analysis of the affected zone is not available to him.
