It requires owners and operators of specific Bell 212 helicopters to modify their emergency float bag assemblies.\n\n**What it does:**\n- Mandates a safety modification to emergency flotation equipment on Bell 212 helicopters\n- Applies to helicopters fitted with specific part numbers of float bag assemblies\n- Requires compliance with Bell Service Bulletin 212-78-9 (the technical instruction document)\n\n**Who it affects:**\n- Owners and operators of Bell 212 helicopters with emergency float bag assemblies bearing part numbers:\n  - 212-050-207-1, -2, -3, or -4, OR\n  - 212-030-411-1, -2, -3, or -4\n\n**Why it matters:**\nEmergency float bags are critical safety equipment that deploy if a helicopter ditches in water. This directive addresses a specific safety issue with these assemblies — likely a design flaw, wear pattern, or failure mode discovered after the equipment entered service. Non-compliance means the helicopter cannot legally fly in Australian airspace.\n\nAirworthiness Directives are legally binding. Ignoring this requirement risks certificate cancellation, fines, and — most importantly — potential equipment failure during an emergency water landing."},"flash_summary":{"complexity_score":2,"scope_assessment":{"changed":false,"description":"The text of the AD defines a clear, limited scope: all Bell Model 212 helicopters fitted with the listed emergency float bag assembly part numbers.
