(See Schedule 1.)\n- The re-made ADs are stated to be \"in exactly the same form as appears in the latest published edition of the Directive.\" The action is taken by a delegate of the Civil Aviation Safety Authority (CASA) under subregulation 39.001(1). (subregulation 39.001(1); Schedule 1.)\n\n**Who is affected\n\n- Aircraft operators, owners, maintenance organisations and engineers responsible for Israel Aircraft Industries 1123 and 1124 (Westwind) series aeroplanes. They are the parties required to comply with the ADs listed in Schedule 1.\n- CASA and its delegated officers, because the instrument is an administrative exercise of CASA’s regulatory powers.\n\n**Why it matters (practical effect)\n\n- The action does not change the technical requirements in the ADs themselves: it is an administrative revocation and re-issue. Operators remain bound by the same inspection, modification, placarding, or limitation requirements that were in the latest published ADs.\n- The immediate practical impacts are administrative: operators must ensure their regulatory records and maintenance compliance files reference the re-made instruments rather than the revoked forms. Any compliance inspections, maintenance planning or safety cases that cite the ADs should be checked to ensure they refer to the current instrument version.\n\n**Official stated purpose and a quick test of that purpose\n\n- Official statement: the ADs are being re-made \"in exactly the same form\" as the latest published directives. That claims the action is administrative housekeeping to ensure the ADs exist as separate instruments in the regulatory register (Schedule 1).\n\n- Testing that claim against likely effects:\n  - Costs and compliance burden: No new substantive compliance costs are imposed by this instrument because the technical content of the ADs is not changed. (Operators already required to follow those ADs remain so.)\n  - Administrative and implementation costs: There is a small administrative cost to CASA (re-issuing instruments) and to industry (updating internal references and records). The risk of temporary confusion exists if operators or maintenance providers rely on an older citation or a different publication format. The instrument reduces the legal risk that an AD could be mis-filed by explicitly creating separate instruments for each listed AD. (Schedule 1.)\n  - Bureaucratic discretion and scope: The instrument is an exercise of a specific delegated power (subregulation 39.001(1)) and does not expand CASA’s substantive regulatory reach — it preserves existing obligations rather than creating new ones.\n  - Effects on private choice and markets: There is no direct change to private commercial freedoms, pricing, ownership or competition stemming from this instrument; any market effects remain those already caused by the underlying ADs (e.g. costs for inspections or parts).\n\n**Other notable points in the instrument\n\n- The Schedule lists the ADs by name and AD number (AD/IAI-W/1 through AD/IAI-W/27). Several entries note amendments (\"Amdt 1\" or \"Amdt 2\"). One entry (AD/IAI-W/4, Wing Flap Hinge and Bearing Inspection) is shown as CANCELLED in the Schedule.\n- The delegate signature and statutory basis for the action are recorded in the instrument (Delegate of CASA; subregulation 39.001(1)).\n\nBottom line: This is an administrative revocation-and-remake of a set of Westwind-series ADs that leaves the substantive technical requirements unchanged while ensuring each AD stands as a separate, current instrument. Operators should check and, if necessary, update their compliance records to refer to the re-made instruments.
