The instrument changes the legal form (revocation and separate re‑issuance) rather than the substantive requirements, which may affect how the ADs are filed, cited, or referenced in other documents (subregulation 39.001(1); Schedule 1; Note).\n- Implementation risk: low for regulatory content because the Note says the re‑made ADs are identical to the latest published editions; the main risks are administrative (ensuring the re‑made instruments are attached, published and accessible).\n\nNet behavioural effect\n\n- The instrument does not impose new or different technical obligations on regulated parties; it changes the legal form and publication status of the listed ADs. Persons bound by those ADs must continue to comply with the same requirements as before (Schedule 1; Note)."},"kimi_summary":{"content_quality":"ok","complexity_score":2,"scope_assessment":{"changed":false,"description":"This instrument maintains the exact same scope as the original directives.

If you don't comply, you can't legally fly the aircraft.\n\n**Which directives are affected?**  \nBoth relate to **lubrication systems** (oil systems) in aircraft:\n- **AD/LUB/1**: Concerns placards (warning labels) on Facet brand scavenge oil filters\n- **AD/LUB/2 Amdt 1**: Concerns oil filter adapters\n\n**Why remake them?**  \nThe note explains each directive is being reissued in exactly the same form as its latest published edition. This is likely an administrative housekeeping exercise—consolidating or reauthorising existing safety requirements under current regulations rather than changing the actual safety requirements.\n\n**Who does this affect?**  \nAircraft owners, operators, and maintenance organisations whose aircraft are subject to these specific directives—likely owners of aircraft with particular engine oil systems using Facet filters or specific oil filter adapters."}},"importantCases":[],"_links":{"self":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-lubrication-systems","history":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-lubrication-systems/history","analysis":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-lubrication-systems/analysis","conflicts":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-lubrication-systems/conflicts","importantCases":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-lubrication-systems/important-cases","documents":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-lubrication-systems/documents"}}
