It was not based on the helicopter manufacturer's own service bulletins. This document formally removes that obligation entirely.\n\n**Who it affects:** Owners and operators of Robinson R22 series helicopters.\n\n**Why it matters:** Operators no longer need to perform this redundant inspection, simplifying maintenance requirements and aligning Australia's rules with the manufacturer's standard guidance."}},"importantCases":[],"_links":{"self":"/api/acts/ad-r22-22-gascolator-fuel-filter-inspection-cancelled","history":"/api/acts/ad-r22-22-gascolator-fuel-filter-inspection-cancelled/history","analysis":"/api/acts/ad-r22-22-gascolator-fuel-filter-inspection-cancelled/analysis","conflicts":"/api/acts/ad-r22-22-gascolator-fuel-filter-inspection-cancelled/conflicts","importantCases":"/api/acts/ad-r22-22-gascolator-fuel-filter-inspection-cancelled/important-cases","documents":"/api/acts/ad-r22-22-gascolator-fuel-filter-inspection-cancelled/documents"}}
