If this happens, the floats may fail to inflate properly when a helicopter lands on water.\n\n**Who must act**: Anyone operating Sikorsky S-76 helicopters with these flotation systems installed.\n\n**What must be done**: Operators must follow the manufacturer's Alert Service Bulletin 76-32-19, which contains the specific technical instructions for inspecting, repairing, or replacing the defective floats. The bulletin is incorporated by reference, meaning its technical requirements become legally binding."}},"importantCases":[],"_links":{"self":"/api/acts/ad-s-76-41-emergency-flotation-system","history":"/api/acts/ad-s-76-41-emergency-flotation-system/history","analysis":"/api/acts/ad-s-76-41-emergency-flotation-system/analysis","conflicts":"/api/acts/ad-s-76-41-emergency-flotation-system/conflicts","importantCases":"/api/acts/ad-s-76-41-emergency-flotation-system/important-cases","documents":"/api/acts/ad-s-76-41-emergency-flotation-system/documents"}}
