They require specific inspections, modifications, or maintenance actions to address unsafe conditions in aircraft. Compliance is mandatory.\n\n**The three directives being remade:**\n- **AD/WILGA/1 Amdt 3** — Sets airworthiness limitations (maximum flight hours/cycles before mandatory inspections or component replacement)\n- **AD/WILGA/2** — Addresses the stall warning system (the device that alerts pilots when the aircraft is approaching a stall)\n- **AD/WILGA/3** — Concerns the tailplane-to-fuselage joint (the critical connection between the horizontal stabiliser and the main body of the aircraft)\n\n**Why it matters:**\nThis is an **administrative housekeeping exercise**. The delegate is not changing the actual safety requirements — the Note explicitly states each AD is being \"re-made in exactly the same form\" as before. This type of instrument is typically used to:\n- Correct technical defects in the legal instrument itself (e.g., citation errors, formatting)\n- Ensure the ADs sit correctly within the regulatory framework under the Civil Aviation Safety Regulations 1998\n- Maintain the legal validity and enforceability of these safety-critical requirements\n\nFor aircraft operators, **nothing changes operationally** — the same inspections, time limits, and modifications remain in force."}},"importantCases":[],"_links":{"self":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-pzl-104-wilga-series-aeroplanes","history":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-pzl-104-wilga-series-aeroplanes/history","analysis":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-pzl-104-wilga-series-aeroplanes/analysis","conflicts":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-pzl-104-wilga-series-aeroplanes/conflicts","importantCases":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-pzl-104-wilga-series-aeroplanes/important-cases","documents":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-pzl-104-wilga-series-aeroplanes/documents"}}
