As of **19 November 2009**, helicopter owners no longer need to comply with that old rule.\n\n**Who it affects:**\nOwners and operators of **Bell Helicopter Textron 205 series helicopters** that have dual hydraulic systems.\n\n**Why it matters:**\nIt removes a compliance burden. The original rule (from 1974) required a specific modification to be done within 50 hours of flight time. This cancellation means that modification is no longer considered necessary for safety, saving owners time and money."}},"importantCases":[],"_links":{"self":"/api/acts/ad-bell-205-17-hydraulic-fluid-temperature-indicators-installation-cancelled","history":"/api/acts/ad-bell-205-17-hydraulic-fluid-temperature-indicators-installation-cancelled/history","analysis":"/api/acts/ad-bell-205-17-hydraulic-fluid-temperature-indicators-installation-cancelled/analysis","conflicts":"/api/acts/ad-bell-205-17-hydraulic-fluid-temperature-indicators-installation-cancelled/conflicts","importantCases":"/api/acts/ad-bell-205-17-hydraulic-fluid-temperature-indicators-installation-cancelled/important-cases","documents":"/api/acts/ad-bell-205-17-hydraulic-fluid-temperature-indicators-installation-cancelled/documents"}}
