This modification allowed pilots to manually release cargo if the normal system failed. The work had to be completed before January 1988.\n\n**Who is affected**\nOwners and operators of Eurocopter AS 355 (Twin Ecureuil) series helicopters that were subject to the original 1988 requirement.\n\n**Why it matters**\nThe rule is being cancelled because the modification deadline passed decades ago. All affected helicopters have already been modified, making the safety requirement redundant. Once cancelled, operators no longer need to track compliance with this specific directive."}},"importantCases":[],"_links":{"self":"/api/acts/ad-as-355-30-cargo-hook-emergency-manual-control-cancelled","history":"/api/acts/ad-as-355-30-cargo-hook-emergency-manual-control-cancelled/history","analysis":"/api/acts/ad-as-355-30-cargo-hook-emergency-manual-control-cancelled/analysis","conflicts":"/api/acts/ad-as-355-30-cargo-hook-emergency-manual-control-cancelled/conflicts","importantCases":"/api/acts/ad-as-355-30-cargo-hook-emergency-manual-control-cancelled/important-cases","documents":"/api/acts/ad-as-355-30-cargo-hook-emergency-manual-control-cancelled/documents"}}
