(See Schedule 1 and the invocation of subregulation 39.001(1).)\n- The Schedule lists 48 items for the Cessna 185 series aeroplanes (AD/CESSNA 185/1 through AD/CESSNA 185/48). Some entries are marked \"Amdt\" (amendment) and some are marked \"CANCELLED\". A note in the instrument says each re-made AD is \"in exactly the same form as appears in the latest published edition of the Directive.\"\n\n**Who this affects**\n\n- Aircraft owners and operators of Cessna 185 series aeroplanes registered in Australia. They must comply with any continuing requirements (inspections, modifications, placards, repairs) set out in the relevant ADs.\n- Approved maintenance organisations and aircraft maintainers who carry out the work required by the ADs.\n- CASA, which administers, serves, and enforces the ADs as separate instruments.\n\n**Why it matters (stated purpose and practical effect)**\n\n- The instrument’s stated purpose is administrative: to revoke the listed ADs and re-issue them as separate instruments in their latest published form. This preserves the substance of each AD while creating an individual legal instrument for each item.\n- Mechanically this means legal continuity: the requirements that operators must follow remain those contained in the most recently published versions of the ADs, but each requirement now exists as a distinct instrument rather than as consolidated material.\n\n**How this changes behaviour and who decides/ pays**\n\n- Who decides: CASA (through its delegate) determines which ADs are revoked and re-made; the legal power used is subregulation 39.001(1).\n- Who pays: operators and maintainers bear costs of compliance with each AD (inspections, parts, labour) where the ADs impose action. This instrument does not itself create new technical requirements or penalties; it re-establishes existing ones in separate legal form.\n\n**Costs, incentives, trade-offs and implementation notes**\n\n- Costs and compliance burden: Because the instrument re-makes the ADs in the same form as the latest published ADs, there is no immediate net increase in technical obligations. The real-world compliance costs are those already attached to the existing ADs (e.g., inspections, part replacements). Those costs fall on operators and maintenance providers.\n- Administrative effect and clarity: Creating separate instruments can make it easier for operators and regulators to cite, track, and enforce individual ADs, but it may increase the number of legal instruments to manage. The instrument relies on the latest published editions of the ADs external to this instrument, which means users must refer to those publications to see the detailed technical requirements.\n- Risk of confusion: Cross-referencing to externally published AD editions creates an implementation risk if stakeholders do not use the correct edition. The Schedule includes items marked \"CANCELLED,\" reflecting that some ADs are no longer in force; those cancellations are recorded here.\n- No substantive policy change: The instrument itself does not amend the technical content of any AD (the instrument states the ADs are re-made \"in exactly the same form\"), so it does not change the underlying safety requirements or expand CASA’s regulatory reach in substantive terms.\n\n**Key references in the instrument**\n\n- The legal authority used: subregulation 39.001(1) of the Civil Aviation Safety Regulations 1998 (as cited in the instrument).\n- The operative list: Schedule 1 lists each AD by title and number (AD/CESSNA 185/1 to AD/CESSNA 185/48), and notes which entries are amendments or cancelled.\n\n**Bottom line**\n\n- This is an administrative housekeeping instrument that revokes and re-issues (in the same form) a set of ADs affecting Cessna 185 series aeroplanes so each AD exists as its own legal instrument. It preserves existing safety obligations without introducing new technical requirements, but it does shift how the rules are organised and where operators must look to find the current text of each AD."}},"importantCases":[],"_links":{"self":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-cessna-185-series-aeroplanes","history":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-cessna-185-series-aeroplanes/history","analysis":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-cessna-185-series-aeroplanes/analysis","conflicts":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-cessna-185-series-aeroplanes/conflicts","importantCases":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-cessna-185-series-aeroplanes/important-cases","documents":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-cessna-185-series-aeroplanes/documents"}}
