They tell owners what inspections or fixes they must do. This instrument:\n- **Cancels two old directives completely** (AD/WHE/1 and AD/WHE/2) — these are marked \"CANCELLED\"\n- **Remakes four existing directives** (AD/WHE/3, AD/WHE/4, AD/WHE/5, and AD/WHE/6) — these continue in force exactly as they were before\n\nThe note explains that the four remade directives are being kept in **exactly the same form** as their latest published versions — no changes to the actual safety requirements.\n\n**Why do this?**\nThis is likely an **administrative housekeeping exercise**. CASA delegates have limited terms, and instruments made by one delegate sometimes need to be formally reissued under a new delegate's authority to ensure they remain legally valid. The substance of the safety rules hasn't changed — only the legal paperwork behind them has been refreshed."}},"importantCases":[],"_links":{"self":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-wheels-and-tyres","history":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-wheels-and-tyres/history","analysis":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-wheels-and-tyres/analysis","conflicts":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-wheels-and-tyres/conflicts","importantCases":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-wheels-and-tyres/important-cases","documents":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-wheels-and-tyres/documents"}}
