1.1. Purpose and scope
The purpose of this Certification Memorandum is to provide specific guideline for those seeking approval for an application for an Approved Model List (AML) Supplemental Type Certificate (STC), an AML Major Change or AML Minor Change. These three kinds of approvals are covered by the term AML-Changes in the frame of this CM. This CM does not add any additional regulation but attempts to clarify how the existing requirements can be taken into account when applying for the approval of an AML-Change.
Additionally, this CM aims to coordinate EASA efforts on the subject of AML-STCs with the policy set by the FAA on similar kind of approvals as detailed in the FAA AC 20-180.
