The Civil Aviation Safety Authority decided this verification rule was no longer necessary for safety.\n\n**Who it affects:** Owners and operators of Robinson R22 series helicopters.\n\n**Why it matters:** Operators can stop maintaining the specific documentation previously required to prove the origin of these tail rotor blades. This reduces administrative burden, though other safety rules for helicopter maintenance still apply."}},"importantCases":[],"_links":{"self":"/api/acts/ad-r22-43-tail-rotor-blades-cancelled","history":"/api/acts/ad-r22-43-tail-rotor-blades-cancelled/history","analysis":"/api/acts/ad-r22-43-tail-rotor-blades-cancelled/analysis","conflicts":"/api/acts/ad-r22-43-tail-rotor-blades-cancelled/conflicts","importantCases":"/api/acts/ad-r22-43-tail-rotor-blades-cancelled/important-cases","documents":"/api/acts/ad-r22-43-tail-rotor-blades-cancelled/documents"}}
