However, since these aircraft are no longer registered in Australia, the cancellation effectively removes a redundant obligation.\n\n**Why it matters**\nThe cancellation took effect on **20 December 2007**. The rule is no longer enforceable because the technical documentation supporting the inspection is outdated, and the affected aircraft have been removed from the Australian Civil Aviation Register."}},"importantCases":[],"_links":{"self":"/api/acts/ad-beech-18-8-undercarriage-limit-switch-inspection-cancelled","history":"/api/acts/ad-beech-18-8-undercarriage-limit-switch-inspection-cancelled/history","analysis":"/api/acts/ad-beech-18-8-undercarriage-limit-switch-inspection-cancelled/analysis","conflicts":"/api/acts/ad-beech-18-8-undercarriage-limit-switch-inspection-cancelled/conflicts","importantCases":"/api/acts/ad-beech-18-8-undercarriage-limit-switch-inspection-cancelled/important-cases","documents":"/api/acts/ad-beech-18-8-undercarriage-limit-switch-inspection-cancelled/documents"}}
