This removes duplicated rules while ensuring the same safety standards apply, since Boeing designs its aircraft under American regulations."}},"importantCases":[],"_links":{"self":"/api/acts/ad-b747-379-airworthiness-limitations-inspections-fuel-tank-systems-cancelled","history":"/api/acts/ad-b747-379-airworthiness-limitations-inspections-fuel-tank-systems-cancelled/history","analysis":"/api/acts/ad-b747-379-airworthiness-limitations-inspections-fuel-tank-systems-cancelled/analysis","conflicts":"/api/acts/ad-b747-379-airworthiness-limitations-inspections-fuel-tank-systems-cancelled/conflicts","importantCases":"/api/acts/ad-b747-379-airworthiness-limitations-inspections-fuel-tank-systems-cancelled/important-cases","documents":"/api/acts/ad-b747-379-airworthiness-limitations-inspections-fuel-tank-systems-cancelled/documents"}}
