This was intended to address safety concerns with the valve mechanism.\n\n**What changed:**\nAs of **12 February 2009**, this inspection requirement is completely removed. The Civil Aviation Safety Authority determined the directive was no longer required for aviation safety.\n\n**Who is affected:**\nOwners, operators, and maintenance organisations responsible for Piper PA-23 series aeroplanes registered in Australia.\n\n**Why this matters:**\nThis removes a compliance obligation and associated maintenance costs for affected aircraft owners. Operators no longer need to track or perform this specific fuel valve inspection to meet regulatory requirements."}},"importantCases":[],"_links":{"self":"/api/acts/ad-pa-23-68-fuel-selector-valve-inspection-cancelled","history":"/api/acts/ad-pa-23-68-fuel-selector-valve-inspection-cancelled/history","analysis":"/api/acts/ad-pa-23-68-fuel-selector-valve-inspection-cancelled/analysis","conflicts":"/api/acts/ad-pa-23-68-fuel-selector-valve-inspection-cancelled/conflicts","importantCases":"/api/acts/ad-pa-23-68-fuel-selector-valve-inspection-cancelled/important-cases","documents":"/api/acts/ad-pa-23-68-fuel-selector-valve-inspection-cancelled/documents"}}
