The cancellation (revocation) takes effect on 21 January 2014.\n\nThe four revoked directives relate to specific Maule aircraft models (designated ML-M4, ML-M5, ML-M6, and ML-M7).\n\n**Who it affects**\n\nAircraft operators, owners, and maintenance organisations who were subject to these specific ADs. Once revoked, these parties no longer need to comply with the maintenance requirements contained in the cancelled directives.\n\n**Why it matters**\n\nRemoving an AD eliminates ongoing compliance costs and administrative burdens for operators. This typically occurs when the safety risk has been mitigated by other means, when the original concern is no longer relevant, or when the affected aircraft are no longer operated in Australia."}},"importantCases":[],"_links":{"self":"/api/acts/casa-adcx-027-13-revocation-of-airworthiness-directives","history":"/api/acts/casa-adcx-027-13-revocation-of-airworthiness-directives/history","analysis":"/api/acts/casa-adcx-027-13-revocation-of-airworthiness-directives/analysis","conflicts":"/api/acts/casa-adcx-027-13-revocation-of-airworthiness-directives/conflicts","importantCases":"/api/acts/casa-adcx-027-13-revocation-of-airworthiness-directives/important-cases","documents":"/api/acts/casa-adcx-027-13-revocation-of-airworthiness-directives/documents"}}
