The Civil Aviation Safety Authority (CASA) has decided the rule is no longer necessary—likely because the safety issue is now addressed differently or the specific risk no longer applies.\n\n**Who does this affect?**\n\nAnyone who owns or operates Sikorsky S-62 series helicopters."}},"importantCases":[],"_links":{"self":"/api/acts/ad-s-62-3-amdt-1-tail-rotor-blades-cancelled","history":"/api/acts/ad-s-62-3-amdt-1-tail-rotor-blades-cancelled/history","analysis":"/api/acts/ad-s-62-3-amdt-1-tail-rotor-blades-cancelled/analysis","conflicts":"/api/acts/ad-s-62-3-amdt-1-tail-rotor-blades-cancelled/conflicts","importantCases":"/api/acts/ad-s-62-3-amdt-1-tail-rotor-blades-cancelled/important-cases","documents":"/api/acts/ad-s-62-3-amdt-1-tail-rotor-blades-cancelled/documents"}}
