Our website and publications are being reviewed to update all references. Any references to EU law and EASA Access guides should be disregarded and where applicable the equivalent UK versions referred to instead.



Supplemental Type Certificates (STCs) are issued to ratify approvals of major changes or major modifications to aeronautical products or any change to the approved type design from applicants other than the Type Certificate Holder or Type Approval Holder.
