The re‑made ADs are reproduced \"in exactly the same form as appears in the latest published edition of the Directive.\"  The ADs to be revoked and re‑made are listed in Schedule 1.\n\n**Who it affects\n\n- Aircraft owners and operators of Dassault Falcon 50 and Falcon 900 series aircraft: they remain subject to the requirements in the listed ADs (maintenance, inspections, retirements, modifications, operational limits, etc.).  Because the ADs are re‑made in the same form, their substantive obligations do not change.  \n- Maintenance organisations and aircraft engineers who perform inspections, repairs or part replacements required by those ADs.  \n- CASA (the regulator), which decides and publishes the separate AD instruments and enforces compliance.\n\n**Why it matters (practical effects)\n\n- Continuity of regulatory obligations: by revoking the old AD instruments and re‑issuing them as separate instruments, CASA preserves the current technical and safety requirements but changes how those requirements are published and referenced.  \n- Administrative/record‑keeping effects: re‑making each AD as a separate instrument can make tracking, citing and accessing individual ADs easier for operators, maintainers and regulators.  \n- No change in compliance costs or substantive obligations: because the text of each AD is reproduced unchanged, operators should not face new technical obligations, timelines, or costs arising from different requirements.  \n\n**Specific mechanical details worth noting\n\n- The instrument lists 32 AD entries in Schedule 1, some of which are already marked \"CANCELLED\" in the list (for example AD/AMD 50/1 and AD/AMD 50/27).  \n- Several listed ADs carry amendment notations (\"Amdt 1\"); those amendments are carried forward as part of the re‑made instruments.  \n- The acting authority is a CASA delegate (David Alan Villiers on the face of the instrument) exercising power under subregulation 39.001(1) of CASR 1998 to revoke and make ADs.\n\n**Testing the official purpose against implementation costs and incentives\n\n- Source's stated effect: to revoke listed ADs and re‑make them individually in their current published form.  The instrument itself explicitly says the re‑made ADs are \"in exactly the same form\" as the latest published editions.  \n- Costs and incentives: because the substantive content is unchanged, the primary costs are administrative (time spent updating internal records, maintenance manuals, compliance checklists and references). Operators and maintenance organisations bear those modest administrative costs.  \n- Implementation risk: the main practical risk is transitional confusion if the separately attached AD instruments are not published or indexed clearly; that risk is administrative, not substantive.  \n- Market effects: no direct effect on competition, prices, ownership or contract freedom; the instrument preserves existing technical and safety obligations and does not introduce new regulatory burdens or relaxation.  \n\n**Who pays, who decides, and what behaviour changes\n\n- Who decides: CASA (through its delegate) decides to revoke and re‑issue the ADs.  \n- Who pays: aircraft owners/operators and maintenance organisations pay any administrative costs to update documentation and ensure work orders cite the correct (re‑made) AD instruments. Any ongoing compliance costs remain as previously required by the AD texts.  \n- Behaviour changes: none substantive — operators must continue to comply with the same AD requirements. The only likely behavioural change is administrative: organisations will update references and documentation to point to the newly issued separate AD instruments.\n\n(Statutory source cited on the face of the instrument: subregulation 39.001(1) of the Civil Aviation Safety Regulations 1998.)"}},"importantCases":[],"_links":{"self":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-amd-falcon-50-and-900-series-aeroplanes","history":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-amd-falcon-50-and-900-series-aeroplanes/history","analysis":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-amd-falcon-50-and-900-series-aeroplanes/analysis","conflicts":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-amd-falcon-50-and-900-series-aeroplanes/conflicts","importantCases":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-amd-falcon-50-and-900-series-aeroplanes/important-cases","documents":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-amd-falcon-50-and-900-series-aeroplanes/documents"}}
