The Civil Aviation Safety Authority (CASA) uses this power to clean up outdated regulations from the rulebook.\n\n**Who it affects**\n- Aircraft owners or operators with planes previously certified under CAO 101.4\n- Anyone involved in maintaining aircraft certification records\n\n**Key details**\n- **Out with the old**: CAO 101.4 is completely abolished (repealed).\n- **Protection for existing aircraft**: If your plane was already legally certified under the old rule before this order took effect, that certification remains valid. The aircraft continues to be recognised as certified in the **transport category** (a classification meaning the plane is approved for commercial passenger or cargo operations).\n- **Why it matters**: This removes obsolete red tape without forcing operators to spend time and money re-certifying aircraft that were already compliant. It’s a housekeeping measure with a safety net."}},"importantCases":[],"_links":{"self":"/api/acts/civil-aviation-order-101-4-repeal-order-2007","history":"/api/acts/civil-aviation-order-101-4-repeal-order-2007/history","analysis":"/api/acts/civil-aviation-order-101-4-repeal-order-2007/analysis","conflicts":"/api/acts/civil-aviation-order-101-4-repeal-order-2007/conflicts","importantCases":"/api/acts/civil-aviation-order-101-4-repeal-order-2007/important-cases","documents":"/api/acts/civil-aviation-order-101-4-repeal-order-2007/documents"}}
