The European rule recognises the compliance with European industry standards.
The declaration form specified in the Organisation Requirements (Part-ORO, Appendix 1) requires operators to declare if they conform to an industry standard. Any compliance with a recognised European industry standard should be taken into account by the competent authority when planning and implementing their risk-based oversight activities. The competent authority may adapt its oversight programme, in order to avoid duplication of specific audit items.
This is further described in AMC1 ARO.GEN.305(b);(d);(d1) ‘Oversight programme’ and AMC1 ARO.GEN.305(b);(c);(d);(d1) ‘Oversight programme’.
