The purpose of the draft AMC/GM presented with this CRD is to reduce the administrative burden on applicants for the approval of a change. The proposed guidance should allow these applicants to come easily to a decision with regard to:

  • whether a design change impacts on operational suitability data (OSD) or not;
  • the classification of changes to OSD as minor or major;
  • the certification basis for the OSD change;
  • the use of their design organisation approval (DOA) for OSD changes.
