This was originally required to be completed within 100 hours of flight time after August 1970.\n\n**What this document does:**\nIt officially cancels that modification requirement effective 18 December 2008. If you own or operate one of these aircraft, you no longer need to comply with this specific maintenance rule.\n\n**Why it matters:**\nThe Civil Aviation Safety Authority has determined this particular safety modification is no longer necessary. This removes a compliance obligation for aircraft owners and maintenance providers."}},"importantCases":[],"_links":{"self":"/api/acts/ad-pa-30-10-fuel-selector-valve-modification-cancelled","history":"/api/acts/ad-pa-30-10-fuel-selector-valve-modification-cancelled/history","analysis":"/api/acts/ad-pa-30-10-fuel-selector-valve-modification-cancelled/analysis","conflicts":"/api/acts/ad-pa-30-10-fuel-selector-valve-modification-cancelled/conflicts","importantCases":"/api/acts/ad-pa-30-10-fuel-selector-valve-modification-cancelled/important-cases","documents":"/api/acts/ad-pa-30-10-fuel-selector-valve-modification-cancelled/documents"}}
