The Civil Aviation Safety Authority cancelled the directive because it had served its purpose (all affected aircraft likely underwent the modification decades ago) and the rule was obsolete.\n\n**Who is affected**\nOperators and maintenance organisations responsible for Eurocopter AS 350 series helicopters. They can disregard the previous cargo hook modification requirement, though any modifications already completed remain valid."}},"importantCases":[],"_links":{"self":"/api/acts/ad-ecureuil-39-cargo-hook-emergency-manual-control-cancelled","history":"/api/acts/ad-ecureuil-39-cargo-hook-emergency-manual-control-cancelled/history","analysis":"/api/acts/ad-ecureuil-39-cargo-hook-emergency-manual-control-cancelled/analysis","conflicts":"/api/acts/ad-ecureuil-39-cargo-hook-emergency-manual-control-cancelled/conflicts","importantCases":"/api/acts/ad-ecureuil-39-cargo-hook-emergency-manual-control-cancelled/important-cases","documents":"/api/acts/ad-ecureuil-39-cargo-hook-emergency-manual-control-cancelled/documents"}}
