It does two things:\n\n1. **Revokes (cancels)** six existing Airworthiness Directives (ADs) for PZL M18 Dromader aircraft\n2. **Remakes** those same six directives as separate, standalone legal instruments\n\n**What are Airworthiness Directives?**\nThese are mandatory safety instructions issued by aviation regulators. They require aircraft owners/operators to inspect, repair, or modify their planes to address unsafe conditions. Think of them as compulsory recall notices for aircraft.\n\n**Which aircraft?**\nThe PZL M18 Dromader — a Polish-made single-engine agricultural aircraft (crop duster) used in Australia.\n\n**Which specific safety issues are covered?**\nThe six directives address:\n- **Airframe** (general structural integrity)\n- **Aileron attach hinges** (the hinges connecting wing flaps that control rolling)\n- **Upper fin rudder attachment** (how the vertical tail's movable part connects)\n- **Vertical fin rear spar** (structural beam in the tail)\n- **Centre wing to outboard wing attach joints** (where the wing sections connect)\n- **Safety belts** (seatbelt inspection requirements)\n\n**Why does this matter?**\nThis is administrative housekeeping. CASA is updating how these safety rules are legally structured — converting them from one format to separate instruments — without changing the actual safety requirements. The note explicitly states each directive is \"re-made in exactly the same form\" as before. This ensures the safety standards remain enforceable under current regulations while improving regulatory clarity."}},"importantCases":[],"_links":{"self":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-pzl-m18-dromader-series-aeroplanes","history":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-pzl-m18-dromader-series-aeroplanes/history","analysis":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-pzl-m18-dromader-series-aeroplanes/analysis","conflicts":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-pzl-m18-dromader-series-aeroplanes/conflicts","importantCases":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-pzl-m18-dromader-series-aeroplanes/important-cases","documents":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-pzl-m18-dromader-series-aeroplanes/documents"}}
