CASA (the Civil Aviation Safety Authority) is cancelling a single, 33-year-old Airworthiness Directive — **AD/SWSA226/82** — effective 3 November 2015.\n\n**Who it affects**\n\nOwners and operators of aircraft subject to this specific directive (appearing to relate to Schweizer 269 series helicopters). If your maintenance program included compliance requirements from AD/SWSA226/82, you can now strike them out.\n\n**Why it matters**\n\nAirworthiness Directives are mandatory safety instructions issued when an aircraft design has a potentially unsafe condition. This repeal removes a compliance burden that had been in place since 1982, likely because the safety risk has been mitigated through fleet retirement, design modifications, or other regulatory means. While this specific obligation disappears, all other safety regulations and directives remain firmly in force."}},"importantCases":[],"_links":{"self":"/api/acts/casa-adcx-016-15-repeal-of-airworthiness-directive","history":"/api/acts/casa-adcx-016-15-repeal-of-airworthiness-directive/history","analysis":"/api/acts/casa-adcx-016-15-repeal-of-airworthiness-directive/analysis","conflicts":"/api/acts/casa-adcx-016-15-repeal-of-airworthiness-directive/conflicts","importantCases":"/api/acts/casa-adcx-016-15-repeal-of-airworthiness-directive/important-cases","documents":"/api/acts/casa-adcx-016-15-repeal-of-airworthiness-directive/documents"}}
