CASA is not changing the safety requirements — it's reissuing the rules under new legal powers to ensure they remain valid and enforceable. The note at the bottom confirms the content stays exactly the same. This kind of remaking is common when regulations are being consolidated or when the legal basis for old rules needs refreshing."},"flash_summary":{"complexity_score":2,"scope_assessment":{"changed":false,"description":"This instrument does not change the substantive scope or technical requirements of the listed Airworthiness Directives.

The effect is a procedural change in legal form rather than a change in substantive obligations."},"complexity_factors":["Narrow, procedural subject matter (revocation and re‑making of existing ADs).","Legal authority invoked is a single subregulation (subregulation 39.001(1)).","Multiple attached instruments listed in Schedule 1 (four ADs) requiring separate handling.","No substantive amendment to technical requirements (Note), reducing technical complexity.","Potential administrative interaction with other published AD records and enforcement systems."],"plain_english_summary":"The CASA delegate has revoked a set of Airworthiness Directives for Diamond DA40 series aeroplanes and re‑made each as a separate, standalone instrument dated 20 December 2004. The re‑issued ADs are stated to be identical in substance to their latest published editions, so the change alters legal form rather than technical obligations.  \n\nThis affects operators and organisations subject to those ADs and mainly imposes administrative updates to records; substantive compliance duties and costs follow from the ADs themselves, not from this procedural re‑making."}},"importantCases":[],"_links":{"self":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-diamond-da40-series-aeroplanes","history":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-diamond-da40-series-aeroplanes/history","analysis":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-diamond-da40-series-aeroplanes/analysis","conflicts":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-diamond-da40-series-aeroplanes/conflicts","importantCases":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-diamond-da40-series-aeroplanes/important-cases","documents":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-diamond-da40-series-aeroplanes/documents"}}
