It formally **cancels Airworthiness Directive AD/A320/146 Amendment 3** — a safety rule that applied to Airbus A320 aircraft — effective 29 April 2010.\n\n**What is an Airworthiness Directive?** Think of it as a mandatory bulletin telling airlines to inspect or fix specific problems with their planes. When CASA revokes one, it usually means the safety issue is resolved, the affected planes are retired, or a newer rule has superseded it.\n\n**Who cares?** Airlines and maintenance crews operating Airbus A320s no longer need to comply with the specific requirements of this particular directive from 29 April 2010 onwards. It is a targeted clean-up removing one outdated obligation."}},"importantCases":[],"_links":{"self":"/api/acts/casa-adcx-009-10-revocation-of-airworthiness-directives","history":"/api/acts/casa-adcx-009-10-revocation-of-airworthiness-directives/history","analysis":"/api/acts/casa-adcx-009-10-revocation-of-airworthiness-directives/analysis","conflicts":"/api/acts/casa-adcx-009-10-revocation-of-airworthiness-directives/conflicts","importantCases":"/api/acts/casa-adcx-009-10-revocation-of-airworthiness-directives/important-cases","documents":"/api/acts/casa-adcx-009-10-revocation-of-airworthiness-directives/documents"}}
