Previously, these operators had to follow specific maintenance or inspection requirements under this directive. Now those requirements no longer apply.\n\n**Why it matters:** Airworthiness Directives are legally binding safety instructions issued by the Civil Aviation Safety Authority (CASA). Removing one means the regulated maintenance action is no longer mandatory, typically because the safety issue has been resolved, superseded by a new rule, or deemed no longer necessary.\n\n**Key details:**\n- **Effective date:** 25 October 2013\n- **Specific rule cancelled:** AD/A320/56 (the 56th airworthiness directive for Airbus A320 aircraft)\n- **Made by:** A CASA delegate under the Civil Aviation Safety Regulations 1998"}},"importantCases":[],"_links":{"self":"/api/acts/casa-adcx-020-13-revocation-of-airworthiness-directive","history":"/api/acts/casa-adcx-020-13-revocation-of-airworthiness-directive/history","analysis":"/api/acts/casa-adcx-020-13-revocation-of-airworthiness-directive/analysis","conflicts":"/api/acts/casa-adcx-020-13-revocation-of-airworthiness-directive/conflicts","importantCases":"/api/acts/casa-adcx-020-13-revocation-of-airworthiness-directive/important-cases","documents":"/api/acts/casa-adcx-020-13-revocation-of-airworthiness-directive/documents"}}
