This directive ensures potentially defective fuel lines on these specific aircraft are identified and fixed before they cause accidents."}},"importantCases":[],"_links":{"self":"/api/acts/ad-aa-5-15-fuel-line-inspection","history":"/api/acts/ad-aa-5-15-fuel-line-inspection/history","analysis":"/api/acts/ad-aa-5-15-fuel-line-inspection/analysis","conflicts":"/api/acts/ad-aa-5-15-fuel-line-inspection/conflicts","importantCases":"/api/acts/ad-aa-5-15-fuel-line-inspection/important-cases","documents":"/api/acts/ad-aa-5-15-fuel-line-inspection/documents"}}
