This inspection had to continue until the fan was replaced with an upgraded part (specifically part number D174-1 at Revision G or later).\n\n**What this document does:**\nIt removes that inspection requirement entirely. Owners no longer need to perform these 25-hour checks or comply with the old directive.\n\n**Who is affected:**\nOwners and operators of Robinson R44 Series Helicopters who were previously subject to the fan inspection requirement."}},"importantCases":[],"_links":{"self":"/api/acts/ad-r44-1-cooling-fan-cancelled","history":"/api/acts/ad-r44-1-cooling-fan-cancelled/history","analysis":"/api/acts/ad-r44-1-cooling-fan-cancelled/analysis","conflicts":"/api/acts/ad-r44-1-cooling-fan-cancelled/conflicts","importantCases":"/api/acts/ad-r44-1-cooling-fan-cancelled/important-cases","documents":"/api/acts/ad-r44-1-cooling-fan-cancelled/documents"}}
