The problem is that the inflation lanyard (the cord that triggers the slide to inflate) can be routed incorrectly, causing the slide to deploy upside-down — which would be useless or dangerous during an emergency evacuation.\n\n**Who it affects:**\n- Operators of BAe 146 Series 100, 100A, 200, and 200A aircraft with serial numbers up to E1017 (for Series 100) and E2048 (for Series 200)\n- This includes airlines, charter operators, and any entity flying these specific aircraft in Australia\n\n**What must be done:**\nOperators must follow the instructions in British Aerospace Alert Service Bulletin 25-A57 to fix the lanyard routing problem.\n\n**Deadline:**\nThe fix had to be completed before 30 April 1986.\n\n**Why it matters:**\nEvacuation slides are critical safety equipment. If they deploy inverted, passengers and crew could be trapped in a burning or damaged aircraft. This directive prevents that potentially fatal failure."},"flash_summary":{"complexity_score":3,"scope_assessment":{"changed":false,"description":"The directive’s scope is defined in the text: it applies to the specified BAe 146 series and serial-number ranges and requires compliance with the manufacturer’s alert by the stated date.
