Transport Canada issued a new directive covering the same safety issue, making the Australian-specific rule redundant. This cancellation prevents duplicate paperwork and ensures operators follow the Canadian safety standard instead."}},"importantCases":[],"_links":{"self":"/api/acts/ad-cl-600-54-amdt-1-overwing-emergency-exit-placards-cancelled","history":"/api/acts/ad-cl-600-54-amdt-1-overwing-emergency-exit-placards-cancelled/history","analysis":"/api/acts/ad-cl-600-54-amdt-1-overwing-emergency-exit-placards-cancelled/analysis","conflicts":"/api/acts/ad-cl-600-54-amdt-1-overwing-emergency-exit-placards-cancelled/conflicts","importantCases":"/api/acts/ad-cl-600-54-amdt-1-overwing-emergency-exit-placards-cancelled/important-cases","documents":"/api/acts/ad-cl-600-54-amdt-1-overwing-emergency-exit-placards-cancelled/documents"}}
