It does two things:\n\n- **Revokes** (cancels) an existing airworthiness directive for DH 90 Dragonfly aeroplanes\n- **Remakes** that same directive as a fresh, standalone legal instrument\n\n**What is an airworthiness directive?** These are mandatory safety instructions issued by aviation regulators. They require aircraft owners or operators to inspect, repair, or modify their planes to fix unsafe conditions. Think of them as compulsory recall notices for aircraft.\n\n**What does this specific directive cover?** The remade directive (AD/DH 90/1) deals with **fire precautions during refuelling** for DH 90 Dragonfly series aeroplanes — a British twin-engine aircraft from the 1930s.\n\n**Why remake rather than just keep the old one?** Australian aviation law was restructured in 1998 with new Civil Aviation Safety Regulations. Older directives needed to be formally \"remade\" under the new legal framework to remain enforceable, even if the actual safety requirements stayed exactly the same.\n\n**Who does this affect?** Owners and operators of vintage DH 90 Dragonfly aircraft in Australia — a very small number of heritage aviation enthusiasts and museums."}},"importantCases":[],"_links":{"self":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-dh-90-dragonfly-series-aeroplanes","history":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-dh-90-dragonfly-series-aeroplanes/history","analysis":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-dh-90-dragonfly-series-aeroplanes/analysis","conflicts":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-dh-90-dragonfly-series-aeroplanes/conflicts","importantCases":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-dh-90-dragonfly-series-aeroplanes/important-cases","documents":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-dh-90-dragonfly-series-aeroplanes/documents"}}
