Once revoked, the affected operators no longer need to comply with these particular maintenance or inspection requirements.\n\n**Which aircraft are affected**\n- **TBM 700** (a single-engine turboprop aircraft): AD/TBM 700/19 Amdt 1 is cancelled effective **8 March 2013**\n- **DHC-8 (Dash 8)** (a regional turboprop airliner): AD/DHC-8/135 is cancelled effective **14 March 2013**\n\n**Why this matters**\nAirworthiness Directives are legally binding instructions issued when unsafe conditions are discovered in aircraft. This revocation means CASA has determined these specific safety measures are no longer necessary — perhaps because the safety issue was resolved through other means, the affected parts are no longer in service, or alternative mitigations have been implemented."}},"importantCases":[],"_links":{"self":"/api/acts/casa-adcx-004-13-revocation-of-airworthiness-directives","history":"/api/acts/casa-adcx-004-13-revocation-of-airworthiness-directives/history","analysis":"/api/acts/casa-adcx-004-13-revocation-of-airworthiness-directives/analysis","conflicts":"/api/acts/casa-adcx-004-13-revocation-of-airworthiness-directives/conflicts","importantCases":"/api/acts/casa-adcx-004-13-revocation-of-airworthiness-directives/important-cases","documents":"/api/acts/casa-adcx-004-13-revocation-of-airworthiness-directives/documents"}}
