Specifically, this applies to changes to the \"dial and pointer presentation\" of 3-pointer type sensitive altimeters.\n- The modification is now treated as if CASA (the Civil Aviation Safety Authority) directly approved it, even though the original order is gone.\n\n**Who it affects:**\n- Aircraft operators who had 3-pointer sensitive altimeters modified before this order took effect.\n- CASA, which no longer needs to maintain the repealed order.\n\n**Why it matters:**\nThis is regulatory housekeeping—cleaning up old rules while ensuring aircraft with existing compliant modifications don't suddenly become illegal."}},"importantCases":[],"_links":{"self":"/api/acts/civil-aviation-order-103-4-repeal-order-2007","history":"/api/acts/civil-aviation-order-103-4-repeal-order-2007/history","analysis":"/api/acts/civil-aviation-order-103-4-repeal-order-2007/analysis","conflicts":"/api/acts/civil-aviation-order-103-4-repeal-order-2007/conflicts","importantCases":"/api/acts/civil-aviation-order-103-4-repeal-order-2007/important-cases","documents":"/api/acts/civil-aviation-order-103-4-repeal-order-2007/documents"}}
