Because helicopter mechanics already perform these checks during routine maintenance, the separate government mandate is redundant. This cancellation streamlines the rules without compromising safety—the inspections still happen, just under normal maintenance procedures rather than a specific legal directive."}},"importantCases":[],"_links":{"self":"/api/acts/ad-bell-206-9-amdt-1-tail-rotor-control-tube-inspection-cancelled","history":"/api/acts/ad-bell-206-9-amdt-1-tail-rotor-control-tube-inspection-cancelled/history","analysis":"/api/acts/ad-bell-206-9-amdt-1-tail-rotor-control-tube-inspection-cancelled/analysis","conflicts":"/api/acts/ad-bell-206-9-amdt-1-tail-rotor-control-tube-inspection-cancelled/conflicts","importantCases":"/api/acts/ad-bell-206-9-amdt-1-tail-rotor-control-tube-inspection-cancelled/important-cases","documents":"/api/acts/ad-bell-206-9-amdt-1-tail-rotor-control-tube-inspection-cancelled/documents"}}
