It requires aircraft owners or operators to take specific action—such as inspections, repairs, or modifications—to address unsafe conditions in an aircraft.\n\n**What this instrument does:**\n- Revokes **AD/B737/240** effective **19 January 2013**\n- Revokes **AD/B737/246** effective **6 February 2013**\n\nOnce revoked, the maintenance requirements and inspections specified in these two directives no longer apply to Boeing 737 operators. This typically occurs when the safety issue has been resolved through design changes, when newer directives supersede the old ones, or when the compliance period has expired."}},"importantCases":[],"_links":{"self":"/api/acts/casa-adcx-001-13-revocation-of-airworthiness-directives","history":"/api/acts/casa-adcx-001-13-revocation-of-airworthiness-directives/history","analysis":"/api/acts/casa-adcx-001-13-revocation-of-airworthiness-directives/analysis","conflicts":"/api/acts/casa-adcx-001-13-revocation-of-airworthiness-directives/conflicts","importantCases":"/api/acts/casa-adcx-001-13-revocation-of-airworthiness-directives/important-cases","documents":"/api/acts/casa-adcx-001-13-revocation-of-airworthiness-directives/documents"}}
