This ED Decision includes acceptable means of compliance (AMC) and guidance material (GM) to Part-21 (Annex I to Regulation (EU) No 748/2012) to facilitate the implementation of the rules related to the approval of changes to operational suitability data (OSD).
The purpose of the draft AMC/GM annexed to this Decision is to reduce the administrative burden on applicants for the approval of a change. The guidance should allow these applicants to come easily to a decision with regard to:
- whether a design change impacts on OSD or not;
- the classification of changes to OSD as ‘minor’ or ‘major’ ones;
- the certification basis for the OSD change; and
- the use of their design organisation approval (DOA) for OSD changes.
