This caused the hook's tongue to bend and release a stretcher during a rescue operation.\n\n**What operators must do:**\n- **Before every hoisting operation:** Follow a specific operational procedure and stop using straps with this hook (as instructed in Eurocopter Alert Service Bulletin 01.33, paragraph 2.A).\n- **Within 2 months of 10 November 2004:** Complete additional instructions from the same bulletin (paragraph 2.B).\n\n**Why this matters:**\nThis directive prevents hoist hooks from failing during rescue or lifting operations, which could cause people or equipment to fall from height. The amendment simply updates the paperwork reference (from a French aviation directive to an Alert Service Bulletin) without changing the actual safety requirements."}},"importantCases":[],"_links":{"self":"/api/acts/ad-gazelle-31-amdt-1-breeze-hoist-hooks","history":"/api/acts/ad-gazelle-31-amdt-1-breeze-hoist-hooks/history","analysis":"/api/acts/ad-gazelle-31-amdt-1-breeze-hoist-hooks/analysis","conflicts":"/api/acts/ad-gazelle-31-amdt-1-breeze-hoist-hooks/conflicts","importantCases":"/api/acts/ad-gazelle-31-amdt-1-breeze-hoist-hooks/important-cases","documents":"/api/acts/ad-gazelle-31-amdt-1-breeze-hoist-hooks/documents"}}
