It cleans up outdated aviation safety legislation, likely because the rules were replaced by newer regulations or consolidated elsewhere. It does not introduce new requirements—it simply removes the old ones."}},"importantCases":[],"_links":{"self":"/api/acts/civil-aviation-order-100-66-repeal-order-2011","history":"/api/acts/civil-aviation-order-100-66-repeal-order-2011/history","analysis":"/api/acts/civil-aviation-order-100-66-repeal-order-2011/analysis","conflicts":"/api/acts/civil-aviation-order-100-66-repeal-order-2011/conflicts","importantCases":"/api/acts/civil-aviation-order-100-66-repeal-order-2011/important-cases","documents":"/api/acts/civil-aviation-order-100-66-repeal-order-2011/documents"}}
