If this happens, the escape slide might not release properly, potentially **blocking the emergency exit** when passengers need to evacuate quickly.\n\n**What must be done:**\n- **Inspect** the cables visually\n- **Replace** any cable that is frayed or broken **before the aircraft flies again**\n- **When:** The first inspection had to be done by 17 August 1990 (unless already checked in the previous 3 months), then **every 12 months** after that\n\n**Who it affects:**\nAnyone operating Boeing 727 aircraft in Australia — airlines, cargo operators, or private owners.\n\n**Why it matters:**\nThis is a **life-safety issue**. In an emergency evacuation, seconds count. A jammed escape slide could trap passengers inside a burning or damaged aircraft. The directive ensures this critical safety equipment works when needed."}},"importantCases":[],"_links":{"self":"/api/acts/ad-b727-119-escape-slide-release-cable","history":"/api/acts/ad-b727-119-escape-slide-release-cable/history","analysis":"/api/acts/ad-b727-119-escape-slide-release-cable/analysis","conflicts":"/api/acts/ad-b727-119-escape-slide-release-cable/conflicts","importantCases":"/api/acts/ad-b727-119-escape-slide-release-cable/important-cases","documents":"/api/acts/ad-b727-119-escape-slide-release-cable/documents"}}
