(See subregulation 39.001(1) of the Civil Aviation Safety Regulations 1998 and Schedule 1.)\n- The instrument states explicitly that each re-made AD is reproduced \"in exactly the same form as appears in the latest published edition of the Directive.\" (See the note in the instrument.)\n\n**Who it affects**\n\n- Aircraft owners, operators and maintenance organisations that operate or service Airbus A319, A320 and A321 series aeroplanes listed in Schedule 1.\n- Organisations that reference these ADs in maintenance manuals, continuing airworthiness records, airworthiness approval documents, or safety management systems.\n- CASA and its delegates (administrative burden of reissuing and maintaining separate instruments).\n\n**How it works, mechanically**\n\n- The delegate uses statutory power (subreg 39.001(1)) to revoke the ADs listed in Schedule 1 and simultaneously reissue each AD as a discrete instrument.\n- The reissued ADs are the same in substance and wording as the latest published editions; no substantive changes to the technical requirements or compliance obligations are made by this revocation/remaking step.\n- The Schedule lists each affected AD by title and AD number (for example, \"Artus Transformer Rectifiers AD/A320/1\" through \"Parking Brake AD/A320/165\"), with many entries showing amendment numbers or a \"CANCELLED\" status.\n\n**Why this matters**\n\n- Compliance obligations continue: operators and maintainers remain bound by the substance of each AD because the remade instruments reproduce those ADs in the same form. In other words, the safety rules do not change by this administrative step.\n- Administrative effect on stakeholders: because the ADs are revoked and re-made as separate instruments, tidy record-keeping and documentary updates may be required. Organisations should check that manuals, maintenance programs and internal compliance references cite the correct (re-made) instrument identifiers.\n\n**Stated purpose and a practical test of effects**\n\n- Stated purpose: the instrument is an administrative action to revoke and reissue the listed ADs as separate instruments and to align the legal instruments with the latest published editions of those ADs (see the instrument's note).\n- Practical costs and incentives:\n  - Who pays: primarily operators and maintenance organisations pay the modest administrative cost of verifying and, if needed, updating internal references and paperwork to reflect the re-made instruments.\n  - Who decides: the CASA delegate exercised delegated regulatory power under subreg 39.001(1).\n  - Behaviour change required: none to the underlying maintenance or safety actions required by the ADs; the main change is documentary (which instrument number/title to cite).\n- Trade-offs and risks:\n  - Benefit: clearer legal form for each AD as a standalone instrument may simplify future amendments and ease legal citation.\n  - Cost/risk: potential short-term confusion if aircraft records or manuals continue to reference the revoked form of a consolidated AD rather than the re-made individual instrument; operators should confirm they are using the correct instrument reference.\n  - Implementation risk is mainly administrative (record updates and ensuring no gap in traceability of compliance history), not technical to aircraft safety.\n\n**Other practical notes**\n\n- Many entries in Schedule 1 show amendment numbers (\"Amdt n\") or are marked \"CANCELLED\"; those markers indicate ADs that have been amended previously or formally cancelled and should be checked individually for their current legal effect.\n- Because the remade ADs are said to be \"exactly the same\" as the latest published editions, this instrument does not itself introduce new technical requirements or remove existing ones. Operators should nevertheless cross-check each re-made AD to confirm its current amendment and cancellation status before acting.\n\n(Primary references: subregulation 39.001(1) of the Civil Aviation Safety Regulations 1998; Schedule 1 and the explanatory note in the instrument.)"},"flash_summary_failed":{"failed":true,"reason":"A positive credit balance is required for all requests, including BYOK, so fallback providers remain available.
