FAQ n.19430

In case the certification basis is CS-25 Amdt 5 (or later) according to part 21A.101 (i.e. STC is a significant change related to EWIS aspects or new product), will the EWIS ICA discriminant (>30 pax or >7,500 lb) still apply?


No, if the certification basis is the CS-25 Amdt 5 (or later), all the large aeroplanes covered by CS-25 shall have to demonstrate compliance with the EWIS regulations without exception.
