If it breaks, the release cable can slip off the pulley, causing the passenger door to jam partially open during an emergency evacuation. This blocks the exit and traps passengers inside.\n\n**Who must act:**\n- Owners of Boeing 747 models equipped with specific escape slide systems listed in Boeing Service Bulletin 747-25-2132\n- Or aircraft with escape systems installed under specific modification certificates: SA574GL, SA575GL, SA744GL, SA745GL, or SA1215EA\n\n**What they must do:**\nFollow the technical instructions in **FAA AD 92-16-08** (an American aviation safety order). CASA has adopted the US requirements but set a specific Australian deadline: **10 December 1992**.\n\n**Why it matters:**\nEmergency evacuation systems must work perfectly in life-or-death situations. A jammed door during an emergency could prevent passengers from escaping a burning or damaged aircraft.
