They require aircraft owners to perform specific inspections, repairs, or modifications when an unsafe condition is discovered in an aircraft design. This instrument removes those specific compliance requirements for the two helicopter models listed above.\n\n**Who this affects:**\nOwners and operators of AS 355 and Ecureuil (Squirrel) helicopters who were previously required to follow the repealed safety directives."}},"importantCases":[],"_links":{"self":"/api/acts/casa-adcx-015-15-repeal-of-airworthiness-directives","history":"/api/acts/casa-adcx-015-15-repeal-of-airworthiness-directives/history","analysis":"/api/acts/casa-adcx-015-15-repeal-of-airworthiness-directives/analysis","conflicts":"/api/acts/casa-adcx-015-15-repeal-of-airworthiness-directives/conflicts","importantCases":"/api/acts/casa-adcx-015-15-repeal-of-airworthiness-directives/important-cases","documents":"/api/acts/casa-adcx-015-15-repeal-of-airworthiness-directives/documents"}}
