ADs are legally binding instructions issued by the Civil Aviation Safety Authority (CASA) that require aircraft owners to fix unsafe conditions in their planes.\n\n**Who it affects**\nOwners and operators of:\n*   HS 125 series aircraft (five specific safety orders cancelled)\n*   Airbus A320 aircraft (one specific safety order cancelled)\n\n**Why it matters**\nThis removes specific maintenance and inspection obligations for these aircraft. Revocations usually occur when the safety issues have been resolved, replaced by newer rules, or the affected aircraft are no longer flying. Once revoked, owners no longer need to comply with these particular safety orders.\n\n**Key dates**\nThe cancellations take effect on two different dates:\n*   **25 March 2010** for one Airbus directive\n*   **22 April 2010** for the five HS 125 directives"}},"importantCases":[],"_links":{"self":"/api/acts/casa-adcx-003-10-revocation-of-airworthiness-directives","history":"/api/acts/casa-adcx-003-10-revocation-of-airworthiness-directives/history","analysis":"/api/acts/casa-adcx-003-10-revocation-of-airworthiness-directives/analysis","conflicts":"/api/acts/casa-adcx-003-10-revocation-of-airworthiness-directives/conflicts","importantCases":"/api/acts/casa-adcx-003-10-revocation-of-airworthiness-directives/important-cases","documents":"/api/acts/casa-adcx-003-10-revocation-of-airworthiness-directives/documents"}}
