Under the power cited (subregulation 39.001(1) of the Civil Aviation Safety Regulations 1998), the CASA delegate, David Alan Villiers, does two things (see instrument text):\n\n- revokes the Airworthiness Directives listed in Schedule 1; and\n- remakes each of those Airworthiness Directives as separate instruments attached to this instrument (see Schedule 1 and the signature block).\n\nA note in the instrument states that each attached Airworthiness Directive is being re-made \"in exactly the same form as appears in the latest published edition of the Directive.\" (instrument note)\n\nSchedule 1 identifies the affected type as Avions Mudry CAP series aeroplanes and lists the subject headings and AD numbers: Engine Mount Welds (AD/CAP 10/1), Fuel System (AD/CAP 10/2), Main Wing Spar (AD/CAP 10/3 Amdt 2) marked CANCELLED, Flight Limitations (AD/CAP 10/4 Amdt 3), Front Tank Support Strap (AD/CAP 10/5), Lower Torque Link Attachment Weld (AD/CAP 10/6), Rudder Lower Support (AD/CAP 10/7) and Aileron Bellcrank Bolts (AD/CAP 10/8). (Schedule 1)\n\n# Who it affects\n\n- The instrument applies to Avions Mudry CAP series aeroplanes, by identification in Schedule 1. (Schedule 1)\n- The immediate decision-maker is the CASA delegate acting under subregulation 39.001(1). (instrument header)\n\n# Why it matters (mechanically)\n\n- Revocation and re-making: the instrument replaces prior Airworthiness Directive instruments listed in Schedule 1 by revoking them and issuing them anew as separate, attached instruments. This is an administrative re-issuance rather than a textual amendment, because the instrument states the re-made ADs are exactly the same as the latest published editions. (instrument note)\n- One listed item is explicitly marked \"CANCELLED\" (Main Wing Spar AD/CAP 10/3 Amdt 2). That entry signals that the prior instrument for that subject is being cancelled rather than re-made. (Schedule 1)\n\n# Practical effects, incentives and who bears the costs\n\n- Primary legal effect: the legal instruments that implement airworthiness requirements for the listed CAP series aeroplanes are reissued under this instrument. Because the ADs listed relate to airworthiness topics (per their titles in Schedule 1), the operational and maintenance obligations those ADs set out remain in force in the form of the re-made instruments. (Schedule 1; instrument note)\n- Who decides: the CASA delegate exercises the statutory power to revoke and reissue ADs (subregulation 39.001(1)). That centralises the revocation/remaking decision at the delegate level. (instrument header)\n- Who pays / bears compliance burden: in practice, the parties who operate, register, maintain or repair the affected CAP series aeroplanes will be the ones to carry out any inspections, repairs, modifications or operational limitations required by the re-made ADs. Those compliance activities create direct costs (parts, labour, aircraft downtime) and administrative tasks (record-keeping, paperwork). The instrument itself does not itemise those costs; it reissues the ADs that set out specific requirements. (Schedule 1; instrument note)\n- Effects on service providers and markets: maintenance organisations and technicians who perform work to comply with AD requirements are the likely recipients of demand created by the ADs. Conversely, aircraft operators face scheduling and cash-flow implications when compliance work is needed.\n\n# Implementation risk, discretion and legal clarity\n\n- Administrative intent: because the instrument expressly re-makes each AD \"in exactly the same form\" as the latest published edition, the action appears to be administrative re-issuance rather than a substantive change to technical obligations. That reduces the risk that this instrument itself alters the content of the ADs. (instrument note)\n- Discretion and legal form: the decision to revoke and reissue is exercised by the CASA delegate under subregulation 39.001(1). Any future changes to the content of these ADs would require separate instruments or amendment processes. (instrument header)\n- Record‑keeping and cross-references: operators and regulatory users will need to consult the attached, re-made AD instruments for the operative text and compliance dates; the short instrument here functions as a wrapper that changes the legal form and placement of those ADs. (Schedule 1; instrument note)\n\n# Trade-offs and opportunity costs (mechanically framed)\n\n- The instrument trades administrative continuity (re-issuing ADs in the same form) for the administrative effort of revocation and re-making. The operational burden on aircraft operators remains driven by the substantive requirements contained in the ADs themselves (listed in Schedule 1). The instrument does not itself create new technical obligations or reliefs beyond cancelling the one item explicitly marked CANCELLED. (Schedule 1; instrument note)\n\n# Short references to the source text\n\n- Power exercised: subregulation 39.001(1) of the Civil Aviation Safety Regulations 1998 (instrument header).\n- Items affected: Schedule 1 (list of ADs and AD numbers; one entry marked CANCELLED).\n- Form of re-issue: note that each attached AD is re-made \"in exactly the same form as appears in the latest published edition of the Directive.\" (instrument note)\n\n"},"kimi_summary":{"content_quality":"ok","complexity_score":2,"scope_assessment":{"changed":false,"description":"The instrument explicitly states it is remaking the directives 'in exactly the same form'—this is purely administrative restructuring with no expansion of scope, new safety requirements, or additional aircraft types covered."},"complexity_factors":["Very short instrument (under 300 words)","Only one substantive provision with two simple limbs (revocation and remaking)","No defined terms requiring interpretation","No conditional logic or nested exceptions","Cross-references limited to a simple schedule table and subregulation citation","Straightforward administrative remaking with explicit 'no change' note"],"plain_english_summary":"This is a technical aviation safety instrument that **revokes and immediately remakes** eight specific Airworthiness Directives (ADs) for a particular type of French aeroplane—the **Avions Mudry Cap 10 series** (a two-seat aerobatic aircraft commonly used for training and competition).\n\n**What it does:**\n- **Revokes** (cancels) eight existing safety directives for these aircraft\n- **Immediately remakes** them as separate, standalone legal instruments\n- Leaves the actual safety requirements **completely unchanged**—the note confirms each directive is remade in exactly the same form as before\n\n**Why do this?**\nThis is a **legal housekeeping exercise**. Under Australian aviation law, Airworthiness Directives are safety mandates that require aircraft owners to inspect, repair, or modify their planes to address unsafe conditions. The Civil Aviation Safety Authority (CASA) periodically consolidates or restructures these instruments to improve administrative clarity, ensure proper legal form, or transition to new regulatory frameworks—without altering the underlying safety requirements.\n\n**Who it affects:**\n- Owners and operators of Avions Mudry Cap 10 aeroplanes in Australia\n- Maintenance organisations servicing these aircraft\n- The eight specific issues covered include: engine mount welds, fuel system integrity, flight limitations, wing spar concerns, tank support straps, torque link attachments, rudder support, and aileron bellcrank bolts\n\n**Why it matters:**\nWhile the safety requirements don't change, this ensures the legal instruments remain valid and properly constituted under current regulations. For pilots and owners, compliance obligations stay exactly the same—this is invisible administrative maintenance of the safety rulebook."}},"importantCases":[],"_links":{"self":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-avions-mudry-cap-series-aeroplanes","history":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-avions-mudry-cap-series-aeroplanes/history","analysis":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-avions-mudry-cap-series-aeroplanes/analysis","conflicts":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-avions-mudry-cap-series-aeroplanes/conflicts","importantCases":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-avions-mudry-cap-series-aeroplanes/important-cases","documents":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-avions-mudry-cap-series-aeroplanes/documents"}}
