This document scraps those Australian-specific rules.\n\n**Why the change?** Since 1 October 2009, Australian law automatically treats American safety directives as Australian law for US-made planes. The US Federal Aviation Administration (FAA) issued a new directive covering the same safety issues, making the old Australian rule redundant.\n\n**What this means for aircraft owners and operators:**\n- You no longer need to follow the old Australian fuel system directive (AD/B727/209)\n- You must comply with the US FAA directive (2008-04-10 R1) instead\n- This simplifies compliance by using the American safety rules directly rather than maintaining a separate Australian version"}},"importantCases":[],"_links":{"self":"/api/acts/ad-b727-209-fuel-system-airworthiness-limitations-cancelled","history":"/api/acts/ad-b727-209-fuel-system-airworthiness-limitations-cancelled/history","analysis":"/api/acts/ad-b727-209-fuel-system-airworthiness-limitations-cancelled/analysis","conflicts":"/api/acts/ad-b727-209-fuel-system-airworthiness-limitations-cancelled/conflicts","importantCases":"/api/acts/ad-b727-209-fuel-system-airworthiness-limitations-cancelled/important-cases","documents":"/api/acts/ad-b727-209-fuel-system-airworthiness-limitations-cancelled/documents"}}
