EASA updated the AMC and GM to Part 21 this month (Issue 2, Amendment 18) alongside aligned changes to Part-M, Part-145, Part-ML, Part-CAMO and Part-CAO. Buried in the detail: revised guidance on the airworthiness review process, on importing aircraft from other regulatory systems under Subpart H, and on aligning occurrence reporting with Regulation (EU) No 376/2014.
None of this is headline news. It's the kind of amendment most design organisations file and move on from. But, as usual, external factors can be a useful prompt to check something: when an occurrence report references a specific design feature, does that link resolve automatically to the requirement and substantiation behind it - or does someone have to go and reconstruct the connection by hand?
That's precisely the kind of cross-reference EASA is nudging closer together with each alignment round. Organisations that already hold occurrence data and design compliance data in the same structured model will barely notice. Organisations that hold them in separate systems, filed by separate teams, will feel the gap the next time an occurrence actually happens.
This is exactly the kind of connective tissue CIVIRES is built for — occurrence data, design requirements and substantiation evidence in one linked model, not three separate systems. If Amendment 18 has you rethinking your continued airworthiness process, we'd be glad to compare notes with us.
