The insulation requirement was a uniquely Australian rule that became unnecessary as aircraft design and maintenance standards evolved. Cancelling it removes a 50-year-old regulatory burden without compromising safety."}},"importantCases":[],"_links":{"self":"/api/acts/ad-pa-24-1-battery-cables-provision-of-insulation-inside-battery-box-cancelled","history":"/api/acts/ad-pa-24-1-battery-cables-provision-of-insulation-inside-battery-box-cancelled/history","analysis":"/api/acts/ad-pa-24-1-battery-cables-provision-of-insulation-inside-battery-box-cancelled/analysis","conflicts":"/api/acts/ad-pa-24-1-battery-cables-provision-of-insulation-inside-battery-box-cancelled/conflicts","importantCases":"/api/acts/ad-pa-24-1-battery-cables-provision-of-insulation-inside-battery-box-cancelled/important-cases","documents":"/api/acts/ad-pa-24-1-battery-cables-provision-of-insulation-inside-battery-box-cancelled/documents"}}
