The cancelled ADs applied to various Cessna aircraft models.\n\n**Who it affects**\nOwners and operators of the following Cessna aircraft models:\n- Single-engine models: 150, 170, 177, 180, 185, 188, 190, 205, 206, 207, 210\n- Multi-engine models: 303, 336, 337\n\n**When it takes effect**\nThe instrument itself starts the day after it is officially registered, but the actual cancellations don't happen until **17 June 2011**.\n\n**Why it matters**\nOnce these ADs are cancelled, owners of these specific aircraft no longer need to comply with those particular safety requirements (usually because the safety issues have been resolved through other means or are no longer considered critical). This reduces regulatory paperwork while maintaining safety standards."}},"importantCases":[],"_links":{"self":"/api/acts/casa-adcx-010-11-revocation-of-airworthiness-directives","history":"/api/acts/casa-adcx-010-11-revocation-of-airworthiness-directives/history","analysis":"/api/acts/casa-adcx-010-11-revocation-of-airworthiness-directives/analysis","conflicts":"/api/acts/casa-adcx-010-11-revocation-of-airworthiness-directives/conflicts","importantCases":"/api/acts/casa-adcx-010-11-revocation-of-airworthiness-directives/important-cases","documents":"/api/acts/casa-adcx-010-11-revocation-of-airworthiness-directives/documents"}}
