Instead, they must comply with a US Federal Aviation Administration (FAA) directive (AD 2008-10-09 R1) that covers the same safety requirements. This ensures Australian operators meet the same standards as American operators for these aircraft.\n\n**Who it affects**: Owners and operators of Boeing 737 series aircraft registered in Australia."}},"importantCases":[],"_links":{"self":"/api/acts/ad-b737-331-airworthiness-limitations-and-inspections-fuel-systems-cancelled","history":"/api/acts/ad-b737-331-airworthiness-limitations-and-inspections-fuel-systems-cancelled/history","analysis":"/api/acts/ad-b737-331-airworthiness-limitations-and-inspections-fuel-systems-cancelled/analysis","conflicts":"/api/acts/ad-b737-331-airworthiness-limitations-and-inspections-fuel-systems-cancelled/conflicts","importantCases":"/api/acts/ad-b737-331-airworthiness-limitations-and-inspections-fuel-systems-cancelled/important-cases","documents":"/api/acts/ad-b737-331-airworthiness-limitations-and-inspections-fuel-systems-cancelled/documents"}}
