The hoists affected are those with part numbers 76370, 76370-010, 76370-011, 76370-020, and 76370-030.\n\n**The safety problem:**\nThe manufacturer found that angle brackets on these hoists were seriously cracked — a defect that could cause the hoist to fail during a rescue operation.\n\n**What must be done:**\n- **First inspection:** Within 10 hours of flying time after 1 December 1988\n- **Ongoing inspections:** Every 200 hours of flying time after that\n- **Permanent fix:** Installing specific replacement brackets (part numbers 709883-100 and 709884-100) ends the need for repeated inspections\n\n**Who it affects:**\nOperators of aircraft equipped with these specific Bronzavia rescue hoists — typically emergency services, search and rescue, and military operators.\n\n**Why it matters:**\nRescue hoists are critical safety equipment. A cracked bracket could cause the hoist to fail during an emergency rescue, potentially dropping a rescuer or casualty. This directive ensures the equipment is checked regularly until a permanent fix is installed."}},"importantCases":[],"_links":{"self":"/api/acts/ad-supp-11-bronzavia-air-equipment-rescue-hoist-attach-brackets","history":"/api/acts/ad-supp-11-bronzavia-air-equipment-rescue-hoist-attach-brackets/history","analysis":"/api/acts/ad-supp-11-bronzavia-air-equipment-rescue-hoist-attach-brackets/analysis","conflicts":"/api/acts/ad-supp-11-bronzavia-air-equipment-rescue-hoist-attach-brackets/conflicts","importantCases":"/api/acts/ad-supp-11-bronzavia-air-equipment-rescue-hoist-attach-brackets/important-cases","documents":"/api/acts/ad-supp-11-bronzavia-air-equipment-rescue-hoist-attach-brackets/documents"}}
